Christopher S. Penn – 00:00
In this five-part series on music and AI, filmed at the 2024 Marketing AI Conference, or MACON in Cleveland, I sit down with composer Ruby King to discuss AI music and the future of creativity. This is part five, the fifth and final part of the song Hungry Eyes on Charing — AI composition in action. That is not at all a chamber —

Ruby King – 00:25
— see what it does in here. See if it changes to altos.

Christopher S. Penn – 00:41
Nope.

Ruby King – 00:45
Not different modes? No. That is a fail.

Christopher S. Penn – 00:49
Yes.

Ruby King – 00:49
If I submitted that, I would be — nope.

Christopher S. Penn – 00:53
Alright, let’s see what variation two of that particular one — who managed to nail it or not? Nope. Immediately.

Ruby King – 01:00
I mean, it’s epic, but it’s —

Christopher S. Penn – 01:02
— it’s epic, but that’s not a chamber —

Ruby King – 01:03
— this is a hungry cat in London. That’s a bit OTT, don’t you think? I mean, ignoring the instructions — soprano one and two, that’s —

Christopher S. Penn – 01:24
— yeah.

Ruby King – 01:25
— and with all the nice — so many times aren’t quite — women of their church, might be. Tenors — it’s hard. Okay. It’s got a separate line of harmony held with no words. Oh, that was interesting. Clipping. The last note of that is a weird one.

Christopher S. Penn – 03:22
Which line are we on? So it has mangled the lyrics. It is no longer following the lyrics.

Ruby King – 03:48
It did follow word painting of that bit. I’m not sure what it’s singing now. I’ve not — oh. Oh, there’s more.

Christopher S. Penn – 04:04
So it has gone back and repeated — is now repeating tenor one and two, which it shouldn’t be.

Ruby King – 04:11
No, it wants to.

Christopher S. Penn – 04:13
It wants to.

Ruby King – 04:13
Who are we to kill creativity?

Christopher S. Penn – 04:15
Let’s see what the second variation is. Any better?

Ruby King – 04:18
Okay.

Christopher S. Penn – 04:18
Nope.

Ruby King – 04:19
Nope. That’s a hard pass.

Christopher S. Penn – 04:22
So out of four variations, it didn’t even get the genre right for three of them.

Ruby King – 04:27
That’s a tricky thing. Also, it completely ignored when it was told brass and baby — pardon? Bass and soprano, and it had its own ideas.

Christopher S. Penn – 04:38
Yes. So obviously, it still has a bit of a ways to go, but that’s the process for building that. And with a tool like Suno, you have to do a bunch of candidates so that it eventually gets one of them right. But, to your point earlier, it’s — you would not have — you would not have paid a musician to make that song.

Ruby King – 05:02
People frequently do.

Christopher S. Penn – 05:03
Really?

Ruby King – 05:04
They do. Yeah. So there’s a lady who came to our university not too long ago. I first saw her because I went to a Royal Albert Hall performance in London, and that was sort of music for royal occasions because it was around the time of big royal occasions, and we thought it’d be great to hear that kind of thing in a big hall. Yeah, it was a lot of very famous music, Zadok the Priest, which is quite an important, famous one. So I went, and one of her pieces — one of the pieces there — was commissioned especially for the occasion. It had never been heard before, and it was the first time we heard it. And I got to meet the composer afterwards, very briefly. I think she signed something, and I ran away all giddy.

Ruby King – 05:51
Then she came to the university afterwards, and she recognized me. Yay. But she had been — I believe she’d been commissioned to write a piece for a chamber choir that was at a church because there are still — when you go to churches, especially in England — I cannot speak of America. I have been here for five minutes. I don’t know what’s going on. But in England, there are old-style churches that still have chamber choirs that still dress in the red and white, with the little frilly stuff — they’re cool, don’t dis it — and they still sing.

Ruby King – 06:26
There are still sometimes gender requirements for — not always, but sometimes there are still, I think — yeah, but they need music, and it’s fine singing the old stuff. But sometimes you want to commission a new piece for a special occasion. Maybe it’s the birthday — 500th birthday of something — and you want to have a special thing. They can be commissioned. They are commissioned, but it depends on what it’s for and how much money there is, whether they even hire you to sing it, let alone if you told this to write that for you. Can it give you the score, the sheet music, to give to your musicians? Because, at the moment, I think the answer is no to that.

Christopher S. Penn – 07:07
The answer is this tool cannot. You can use other tools to decompile it.

Ruby King – 07:11
Okay. I’m not sure how effective that would be, bearing in mind some of those notes were kind of — I know this is meant to be loud with a lot of notes, and there’s some notes in here — don’t listen to all of them.

Christopher S. Penn – 07:21
No, I meant it’s unlikely someone would write a — commission a song about a hungry cat just for fun.

Ruby King – 07:29
There have been stranger things.

Christopher S. Penn – 07:31
Fair enough. Okay. But yeah, that’s the process for how you would use generative AI. Today, it’s not something you can do all in one tool that’s going to be highly effective. It’s going to be something you have to do across multiple tools that will change over time, as well as the audio models themselves will get better over time. Thanks. So I guess that leaves us at the end of this to say, what do you think about the future of music, given what we worked on, what you know of the industry, and what you know of the way AI is going?

Ruby King – 08:06
I think it’s going to change. I know that a lot of people are concerned and hoping for the best that — I think it’s a tricky situation because a lot of it does come down to laws and people in other countries a long way away from most of the people I know in the industry and what they decide. It also depends a very large amount on the morals and ethics and beliefs and preferences of the people who have the money to usually commission that music. The music industry has already changed so much because of streaming. I mean, back in the day — a very, very long time ago — you would live in the residence of someone who would pay you to write the music. And then a patron. Yeah, exactly. It’s not like that anymore.

Ruby King – 09:02
Back in my day, not quite, but that was the way it was, and now that’s nearly unthinkable. I can’t think off the top of my head of anyone who’s in that particularly great situation. But streaming has changed it, and streaming pays so little that it’s a real problem, and it can’t continue forever. But where that line is — where it changes — is it going to change in favor of musicians and giving us a fair cut of what our work is worth, or is it going to change? “We didn’t need you anyway. AI will now be what we have, and we will invest all our money in improving AI rather than paying you enough money to incentivize you to write good music.” Because we’re not — musicians, composers have to do a lot of work to get our music — their music heard, and that will no longer be anything but a hobby if the money from Spotify and stuff is sent over to preference of AI and trying to get that to be the best that it can be so that more people go, “Okay, that was the old times. This is the new times. You have to be up and with it, with the new times. Goodbye humans, hello machines.”

It all does depend on so many different things. I think it’s impossible to say right now what is going to happen. Anyone who is predicting the future — which is a bad — don’t do that. Doesn’t work.

Christopher S. Penn – 10:31
I would agree, with the caveat that some — this is, as a psychology person — some human behaviors are very predictable. Greed and stupidity are highly predictable. People generally want better, faster, and cheaper. That’s highly predictable. People want to be entertained and engaged, and to some degree, educated. With that backdrop, given how the industry of music functions, it is highly probable that at least in the short term, there will be — music industries will see — music companies will say, “We can save a lot of money by not paying humans and generate music that people will find acceptable enough.”

Ruby King – 11:15
Which is why it also depends on laws and rules. I’m not sure what happened with — something that — there was such a lawsuit where Open — it was OpenAI — said, “We can’t do what we do without this content.” Are they being told they can’t?

Christopher S. Penn – 11:31
Well, those court cases are going to take years to work out, so it is unclear.

Ruby King – 11:37
Okay. Well, that could help musicians in the future. It could. And if that cloud is over the heads of tech companies, then investing every single penny into making it as great as possible might be slowed down because if it isn’t — if there’s a possibility that all that money is wasted — then greed dictates that money being wasted is bad.

Christopher S. Penn – 11:58
Right. So, for those independent companies, that’s true. What is probable is that it will hyper-concentrate into the tech companies that have the legal standing — Google and Meta — as the company’s, “Hey, you’re using Instagram and Facebook and YouTube. You gave us licenses. So here’s our models that are now the best-in-class models because we have the legal standing to say, ‘You told us we can make derivative work. So here’s your stuff.’”

Ruby King – 12:24
Yes. Yeah. Well, with greed, the music industry has got so much greed in it already. It’s infested. It’s really a difficult thing to get into, especially for minorities or anyone, but the usual, which I don’t have to explain. So it’s hard enough as it is, and then you add in all these other things, and it’s — things are only going to get worse. I would like to say until they get better, but I’m not sure you can predict that either.

Christopher S. Penn – 12:59
No, we cannot.

Ruby King – 13:00
No.

Christopher S. Penn – 13:01
No. Alright, well, thank you. I appreciate your time for this series. We’re going to publish this as a series because no one’s going to sit through 90 minutes of this. And thank you very much.

Christopher S. Penn – 00:01
In this five-part series on music and AI, filmed at the 2024 Marketing AI Conference, I sit down with composer Ruby King to discuss AI music and the future of creativity. This is part four, teaching AI to write lyrics — a deep dive into chamber choir music. Okay, so let’s do this. Let’s transition here. I’m going to go ahead and share my screen, and we’re going to see how well — yay, infinity tunnel — let’s go here to Bard first, and then AI Studio. So I’m going to use Google’s AI Studio, and the first thing I want to do is I want to get an understanding of what constitutes good songwriting. So I’m going to ask you to evaluate the model’s thing. So your topic is best practices for — what genre of music do you know very well that has lyrics? Pop, rock —

Christopher S. Penn – 00:58
— I guess it’s more grunge.

Ruby King – 01:00
No, no, it’s more — it’s classical pieces that have lyrics.

Christopher S. Penn – 01:08
I mean, Gregorian chants.

Ruby King – 01:11
No, chamber choir music or something like that, where there’s four parts or that kind of thing. I can do that.

Christopher S. Penn – 01:18
Lyrics to chamber choir pieces. So that is what we’re going to go for. We’re going to choose the Gemini model. We’re going to choose an output length of 16,384 tokens.

Ruby King – 01:32
Does it have to be with words for this one?

Christopher S. Penn – 01:34
Because you’re looking at — well, we wanted to do stuff with lyrics, and the reason we want to do it with lyrics is specifically because, for tools like Suno in particular, part of the generation is the lyrics themselves. That’s part of the prompt. So let’s see what Gemini has to say: “Best practices for generating lyrics for chamber choir pieces. Understanding the vocal capabilities and limitations of a chamber choir. Voice types and ranges. Blending and balance. Ensemble size and dynamics. Text selection. Text — choosing appropriate texts. Considerations for length, subject matter. Word painting and musical expression.”

Ruby King – 02:18
Example, word painting. That’s good.

Christopher S. Penn – 02:20
Okay. “Syllabic versus melismatic setting.”

Ruby King – 02:24
Yeah. Melismatic is when there was that singing before where it had no words.

Christopher S. Penn – 02:29
Okay, got it.

Ruby King – 02:31
AI doesn’t do that terribly well, but it’s singing multiple notes to a sound.

Christopher S. Penn – 02:35
Okay. “Creating unified, engaging musical structure, form, and development. Strophic through composed ABA. Vocal lines and harmony, repetition and variation. Practical considerations of performance. Score clarity and readability. Accessibility and singability. Common mistakes of less experienced practitioners. Writing ranges that are too wide or uncomfortable.”

Ruby King – 02:53
Yep, absolutely.

Christopher S. Penn – 02:55
“Neglecting vocal blended balance.”

Ruby King – 02:59
Can be a choice, but yeah.

Christopher S. Penn – 03:01
Okay. “Overlooking dynamics on ensemble size. Choosing texts that are unsuitable for choral music.”

Ruby King – 03:07
Yeah.

Christopher S. Penn – 03:08
“Overusing or misusing word painting. Inconsistent or inappropriate syllabic choices. Lack of musical structure development. Weak or unclear form. Uninstrung or unbalanced vocal lines. Neglecting practical considerations. Chamber choirs can — we sing quiet, introspective music that is generally to be true, but is actually false.” Really? “Rhyming lyrics are essential for chamber music.” Over there.

Ruby King – 03:34
I wouldn’t say so. A lot of the time, we’re singing just words straight from the Bible.

Christopher S. Penn – 03:38
Right. So they’re saying these are things that people believe to be true but are actually false.

Ruby King – 03:42
Okay. Yes, that’s true.

Christopher S. Penn – 03:43
“Latin texts are always more appropriate.”

Ruby King – 03:46
Yeah.

Christopher S. Penn – 03:47
Okay. “Things that are believed to be false but are actually true. Simple text can inspire profound choral music. Silence can be a powerful element. Collaborating with a living poet can enrich the creative process. Tips and tricks. Listen deeply to singers. Sing the parts yourselves. Study a choral score.” So these are all things you would say are appropriate for what you should know to create good chamber music.

Ruby King – 04:13
Yeah, I mean, I’ve not seen anything I disagree with.

Christopher S. Penn – 04:16
Okay. Is there anything missing that you know of that it didn’t know?

Ruby King – 04:23
Did it speak about the spaces that things are being sung in? I didn’t see that there. But it does also — if you’re singing in a really big church, you might choose — the amount of singers might be different with how many parts you split into.

Christopher S. Penn – 04:37
No, because we specified writing lyrics.

Ruby King – 04:41
Yes. Yeah. Okay. Yes. Lyrics also matter here, though, because if you’ve got — chamber choir is four parts, usually. So if you’ve got — if you’re writing lyrics and you’re in different spaces, you might want to write more words in a shorter period of time with lots of people doing different words. If you don’t care — what if — if you’re in a church service, usually when you’re hearing chamber choir, you want to hear the words that are being said because it is about worship, and that is the idea. If it’s a concert of chamber choir music for a different purpose, then you might have lots of different interweaving lines. But when it was for church services, I’d mostly have everyone singing the same word at the same time, but different notes.

Ruby King – 05:30
So it was nice to hear, but a few passing notes in emphasizing words, but it does change with the purpose of the service or the purpose of the music.

Christopher S. Penn – 05:42
Okay, so next, let’s have it create a scoring rubric. So next, create a scoring rubric that can evaluate a set of chamber choir lyrics and how well they adhere to our best practices and tips and tricks so far. The individual items in the scoring rubric should be scored as variable integers: zero to three, zero to five, zero to seven, etc. The rubric — hide that because I can’t see what I’m doing. There we go. The rubric as a whole should total 100 points. The purpose is to give lyrics an assessment of how well they conform to best practices. So let’s see what the model comes up with. So it’s going to say, “Here is how to score a set of lyrics.”

Ruby King – 06:55
Oh boy, okay. Just letting you know, this — again.

Christopher S. Penn – 07:05
Well, this is — this scoring rubric is one of the magic terms in generative AI, where you’re saying to the model, “I want you to evaluate.” And instead of saying, “Model, is this good or bad?” — because the model doesn’t know — you give it a set of scores that then it can use as a baseline. Say, “Here’s how — what I think I understand about this.” So let’s save this. This is our Gemini chamber choir lyrics gem rubric. Okay, so we’ve got our rubric now. Now let’s have it generate some lyrics, some chamber choir lyrics. What topic should we use?

Ruby King – 07:57
Usually, it’s sacred.

Christopher S. Penn – 07:58
Okay, let’s not offend anyone.

Ruby King – 08:00
Okay.

Christopher S. Penn – 08:04
Remember, this is a generative AI model, so it can make anything about anything.

Ruby King – 08:09
Okay. Chamber choirs are usually used for slow, solemn things. So if we do — usually, it’s quite effective if it’s sad or crying. So it just — you can have more upbeat ones, but usually, that’s all right.

Christopher S. Penn – 08:27
So let’s do this. Alright, next, generate two candidate sets of lyrics. The overall topic for the song should be a cat that is prowling around the streets of London, hungry. The lyrics should reflect this general situation and tell a story. Generate two candidate sets of chamber choir lyrics for this story. London’s tomcat prowl. Soprano one, alto one.

Ruby King – 09:16
Did it just start the word with “sh”? How are you meant to sing “sh”? I mean — okay, some of the time it does just write that, and then you make the sound, but we had music, though. We literally had to all go “quack” at the same time with notes. That’s just what happens, but it’s not a strong start.

Christopher S. Penn – 09:37
Okay, so we have candidate one, London tomcat prowl.

Ruby King – 09:43
Oh, they’ve got it in different — are they split into — okay. Soprano one and two. Okay, so split the sopranos and altos and tenors and basses into one and two. Okay, that’s alright.

Christopher S. Penn – 09:55
Okay, now score each candidate according to our rubric.

Ruby King – 10:05
“I did great. Thanks for asking.” Oh, it’s quite mean.

Christopher S. Penn – 10:23
So the first candidate scored 79 out of 100. The second one scored 82 out of 100. Great. Make a refinement of candidate two that improves the overall score. Create the candidate refinement and score it. So what we’re doing here — this is a three-part process that we use for generative AI when we’re doing anything commercially with generation, which is create, score, refine.

One of the things people do the most wrong with generative AI is to say, “Just do the thing,” and they accept the output — “Build!” — and they’re, “Oh, it kind of sucks. Generative is not very creative.” Well, no, you failed to prime the model. You failed to understand the context, and then you gave it a prompt that was stupid and insufficient. And so what we’re doing here is we’re basically telling the model, “You need to keep improving until you get it right.”

Ruby King – 11:33
That’s what my math teacher used to say: “Rubbish in, rubbish out,” too.

Christopher S. Penn – 11:37
So here’s candidate two refinement. Hungry eyes on Charing Cross. You can see it’s revised for better sound, revised for a smooth line, and so on and so forth. And so this refinement, it now scores an 88.

Ruby King – 11:50
Okay. Make it even better.

Christopher S. Penn – 11:54
Yes, essentially. See? Great. Take the refinement and improve it until it — improve it so that it scores better. So this is candidate set to refinement two, revised for alliteration and imagery, revised for more specific imagery, stronger association, stronger metaphorical language.

Ruby King – 12:24
Oh, it’s scoring a lot better now.

Christopher S. Penn – 12:26
Mm-hmm. And it tells you the justification.

Ruby King – 12:30
Hold on. I got eight out of seven there. That’s cheating.

Christopher S. Penn – 12:34
That is cheating. So it scored a 90. Now, the next thing we want to do — so every — almost every model that’s made out there, like Suno’s, has at some point, probably used a generative language model as its foundation. So what is — what are the characteristics? How would you tell someone else to compose a piece of chamber music?

Ruby King – 13:05
That’s very difficult. You mean lyric specifically?

Christopher S. Penn – 13:09
No, no, the music, the music itself. What would be the musicality? I’m going to save this — the lyrics themselves. I’m going to — great. Show me the final version of the refined lyrics without any of the notes for improvements. So what we want is just the clean lyrics. Okay, so we have our final lyrics here. That’s our song title, Hungry Eyes on Charing Cross. How would you give instructions to a composer to write the music that goes —

Ruby King – 13:58
— with this word painting? Okay, bearing in mind, what have we got? Beneath the gaslight amber gleam — the lines look about equal. So probably write a melody that aligns with the word painting of the idea of the piece because if it’s going to be repeated, they can’t work for every single line necessarily. Use that in the way it’s written in. It might just be an AAA structure here. It’s hard to tell because it’s just doing different sections.

Christopher S. Penn – 14:49
Okay, let’s ask it. See what it — what do you know about composing the musical to accompany these lyrics? Emotive, atmospheric, quiet introduction. Tenors and basses, soprano, alto, tenor, all voices. Is there instrumentation in chamber choir music? Is it all human singing only?

Ruby King – 15:08
There can be, but chamber choirs usually don’t have it because there’s so many different parts, and all the voices kind of work together. It’s a bit more like a string quartet. You can have other instruments with a string quartet, but the string quartet is, of its own, a string quartet that is capable of doing pieces of its own.

Christopher S. Penn – 15:23
Got it. Okay. What instructions would you give a composer to generate the music for this? Focus on technical specifics like tempo and key. So we’re going to essentially ask the model to distill down the instructions that it would give to a composer because when we get to the Suno portion, we want to feed it very specific instructions that hopefully will evoke the correct tokens in its memory to pull together its knowledge. The challenge is Suno’s prompting structure is intentionally very short so that you can’t give it highly specific instructions to replicate copyrighted music. So it has to be distilled down. So great. Distill down these instructions to 200 characters of text. Omit verbs.

Ruby King – 16:33
London night is not an instruction.

Christopher S. Penn – 16:35
Yes.

Ruby King – 16:36
Minor key is — tempo shift. Good word painting. Yes. Dynamics? Pianissimo, mezzo forte, fortissimo. No. Okay.

Christopher S. Penn – 16:45
Eliminate references to the content, such as London Night, so that our 200 characters of instructions are devoted to the music composition.

Ruby King – 17:03
Also, why does it want an unresolved ending?

Christopher S. Penn – 17:06
I don’t know. It seems to think that’s important. So that’s the unresolved question. Consider cello or piano optional.

Ruby King – 17:15
No, no, we’re not doing that here. Nice try.

Christopher S. Penn – 17:18
Okay, so let’s copy this into seven structures. We’re going to remove that because we’ve decided that’s not going to be something we do.

Ruby King – 17:25
It’s actually written out pianissimo, fortissimo this time.

Christopher S. Penn – 17:27
Yes, because we gave it more room. So this is 255 characters. So we might have to —

Ruby King – 17:34
— as long as Suno will — you do — Suno understands?

Christopher S. Penn – 17:38
Yeah. So we’re down to 227. Very texture. Let’s get rid of the unresolved ending. Now we’re at 201. Minor key.

Ruby King – 17:48
Chamber choir isn’t instructing — chamber choir. Elsewhere?

Christopher S. Penn – 17:53
Yeah, it’s right down here. So we’re at 187. So now let’s go into create mode. We’re going to do custom. We have — oh, it’s — sorry. It’s 120 characters.

Ruby King – 18:09
Okay. To be fair, the dynamic range doesn’t need to say that because that is — as quiet as you can go to as loud as you can get, pretty much. So just full dynamic range.

Christopher S. Penn – 18:17
So what if we do word painting? So you said full — just full dynamic range.

Ruby King – 18:21
It is, maybe, yeah.

Christopher S. Penn – 18:22
Okay, so we’re at 107 characters. Let’s do homophonic, polyphonic. That’s 151 standard chamber. Actually, just probably just chamber choir, right?

Ruby King – 18:38
Yeah, we’ll see what it does if it needs —

Christopher S. Penn – 18:41
— okay. Anything else that we could remove there other than that comma? We’re seven characters over still.

Ruby King – 18:57
When it has the dashes, is that saying, “Do it this, then this, then this”?

Christopher S. Penn – 19:01
Not necessarily. That’s just how it spit it out.

Ruby King – 19:03
Okay, then take out andante.

Christopher S. Penn – 19:09
Take out andante. Okay, so now we’re at 119, which is perfect. So let’s go ahead and take our — that’s going to be our song title. We’re going to put that down here as candidate one. Our lyrics — we’re going to get rid of the bolding. We don’t need it. Cut that into here.

Ruby King – 19:33
I can tell you’ve done this a lot of times before.

Christopher S. Penn – 19:35
Yes. And then we’re going to take our instructions for style of music, 119. Just to be on the safe side, I’m going to move chamber choir to the top of the instructions.

Ruby King – 19:46
Okay. I don’t want to rope a piece that is, “This cat is hungry.”

Christopher S. Penn – 19:51
And we’re going to create variant one. Is there anything that you would change?

Ruby King – 20:00
What, at this stage?

Christopher S. Penn – 20:01
At this stage, in terms of the musical instructions.

Ruby King – 20:08
Close, dissonant harmonies. It depends when it uses it. I think that’s a difficult one because dissonant harmonies do work as long as they’re resolved. If they’re not resolved — if it just closes, dissonant harmonies, then you don’t want to listen to it. I mean, dissonance is an interesting thing to use, but it’s only satisfying if it resolves.

Christopher S. Penn – 20:28
Okay. I pulled out homophonic, just went with polyphonic. So I did a second variation with that. Let’s see what it’s come up with for our variations. Are you ready?

Ruby King – 20:37
Yeah. Alright, I’m ready.

Machine-Generated Transcript

What follows is an AI-generated transcript. The transcript may contain errors and is not a substitute for watching the video.

Christopher S. Penn – 00:01
In this five-part series on music and AI, filmed at the 2024 Marketing AI Conference, or MACON, I sit down with composer Ruby King to discuss AI music and the future of creativity. This is part three, the ethics of AI music, consent, and the future of musicians. So, based on what you’ve heard, what would be, to you, the use cases for using this type of output? I imagine things like, for example, hold music.

Ruby King – 00:30
The quality of phone lines — is anyone going to be able to actually hear it properly? Exactly. I mean, we have Vivaldi Spring on our hospital line, and that’s so crackly that it may as well just be a rat playing it. Yes. So wait things — that does work for the quiet backgrounds of music, videos, too. But it does depend how lively it is because that is quite lively, and it’s got quite a strong feel to it. You kind of want to move to it a little bit. So if you’re doing a talk and that is playing, then obviously no. But that’s the same if you had a piece that’s performed, and you’ve got the rights for it to have it there, you’ve still got to choose your music wisely. That doesn’t change whether it’s AI or not.

Ruby King – 01:24
That performance sounded like a good, well-recorded piano, and it sounded at least 99% possible to play, I believe. It is hard to tell listening like that, but there was none of it where I was thinking, “Okay, these hands are not happening.” You’ve seen those things where you can make the piano sound like a voice, but you can’t do it with your fingers because it uses too many frequencies all at the same time to make it sound like it’s saying —

Christopher S. Penn – 02:06
— you need 14 fingers on each hand.

Ruby King – 02:08
More. Yeah. There is a wide variety of use cases, as much as I hate to say it.

Christopher S. Penn – 02:17
Okay, so talk about that.

Ruby King – 02:18
Yeah. Okay. Why I hate to say it?

Christopher S. Penn – 02:22
Yes. Because there’s sort of this push and pull of the AI side of things, saying, “Hey, this is a great substitute,” say, for royalty-free music, where you get your stock — whatever — download of your 200,000 songs, all of which are pretty much that. Or you can have something that’s custom-made by a machine that is equally — but you don’t have to pay $49.95 for it.

Ruby King – 02:53
Yeah. Okay. I suppose it comes down to two things. One of those is morals. So I mean, you can try and —

Christopher S. Penn – 03:01
— ignore morals, but many people do.

Ruby King – 03:04
Yeah. So when it’s royalty-free music or something, then someone has given their consent for it to be that, usually. I think it’s — if you’re buying the pack, then somewhere along the lines, the musician got money. They went, “I’ve written this piece. Do you want it?” They went, “Yes, we want it. You either have no royalties to it,” or whatever the signage is, depending on where it is, I guess. “Can we have it?” “Yes, you can. Here’s some money.” Probably not enough, but okay, deal done. That is given with consent.

When it comes down to AI, there is not much consent around here, and people seem to have a very decent understanding of when consent is involved with things of a nature that is not necessarily IP and might be more related to humans. And while it may not seem as bad — non-consensual anything else — when you are using AI to write music, it’s still without consent. You are using other people’s work, effort, and time without their consent in order to write something for yourself when you could have paid them either nothing — they might have given it to you for free — or a very small pittance. Musicians don’t make a lot. There is — you could get it for a little bit of money and sleep better at night, maybe.

Christopher S. Penn – 04:33
Okay.

Ruby King – 04:34
But in the way of, “Is it actually better to have a musician do it for the end product?” More and more, the answer is becoming it’s not that important because it is improving. I would say right now, it’s not perfect enough for musicians to be completely ruled out because there are issues with it. When you are listening to it, depending on the level of your training or the amount you care, it’s not right. There are issues with it. But if you really don’t care, and it’s for something that you’re not willing to pay any money for, and you’re, “I can just generate this. Why would I pay anyone for it?” Well, yeah, sure, okay. If you don’t care, then it works.

It does the job that you want it to do, and it does that very well in a lot of cases. I have listened to some Bach or Mozart that’s AI-generated. So it’s not actually them, but it’s told to — yeah, exactly. And it sounds fairly convincing. It sounds like it might actually be an orchestra playing it.

Christopher S. Penn – 05:42
Right.

Ruby King – 05:44
But there’s no real melody to it, and it’s kind of — it’s not quite right. But if you’re doing — if you’re studying and you’re listening to that at the same time, for the sake of not having something that you know and are singing along with in your head, then it works. It does the job. A lot of AI is increasingly going to just do the job, and it is a concern for musicians and composers that it is just improving and improving. It’s using our work without our consent to do so and thus taking away quite a lot of the importance of teaching music, which is already at the bottom of the barrel in quite a lot of countries, including England.

It should be more important. But if the tech industry keeps doing this, then the tech industry will become more important, music will be less important, and then we have a — this is a whole different topic. I’m really sorry.

Christopher S. Penn – 06:39
Well, the consent thing is important because, yes, companies — Suno and Mubert — allegedly, because this is in court, you have to say allegedly, otherwise lawyers come out — did ingest large amounts of copyrighted music. And there’s one industry that’s really good at suing people: it’s the music industry. However, one of the biggest repositories of music consent is baked in, and that is YouTube.

When — if you look at the terms of service for YouTube — any material you upload to YouTube, you grant Google a perpetual license to make derivative works of your content in perpetuity, anywhere in the universe, and that includes AI models. So Google could take all the YouTube music that’s been given to it and say, “Well, you signed the terms of service, you agreed to it. And therefore, this model that we have now built from your work, you consented to.”

Christopher S. Penn – 07:36
In a case like that, if Google then rolls out the music generation model, which they have, how does that change the moral aspect?

Ruby King – 07:47
I don’t think morals — I don’t think the moral aspect changes too much because if you’re trying to justify your morals by going, “Here, in the fine print, it said I can do what I want,” then your morals need looking at. Legally is different to morally.

Christopher S. Penn – 08:06
Yes. And legally, Google is on solid ground, whereas Suno is not necessarily.

Ruby King – 08:11
Yeah. So it kind of comes down to, as well, the Disney situation did — whoever — I don’t know the full story of that, but they’re kind of trying to get — because they signed up for Disney Plus.

Christopher S. Penn – 08:23
Oh, yeah, the whole thing.

Ruby King – 08:24
Yeah. Did they actually consent to that? Is it morally right to go, “Oh yeah, but you signed your life away when you signed that little box because you wanted to watch the Marvel movies at home. How dare you? How very stupid.” Did you actually consent to that? No, but we are in a society where if you do not agree to the terms and conditions, you can’t use the service. You cannot use the service.

For musicians, there are so many — there’s not actually that many companies that will help you be heard. So Spotify, Apple Music — there’s lots of others, but they are smaller and less used. You have to be on those if you want your music to be accessible to people because that’s where people are. You have to go there. It doesn’t mean I necessarily want to agree to the terms and conditions, but if I want to have a chance in heck of having that being heard by anyone, then you’ve got to upload there. The same with Facebook or advertising on Instagram. You have to have an Instagram page. You have to have a Facebook page to say, “Hey, this is where the people are. I have music I think you would like to listen to, and I’d like you to listen to it. Here’s a link on something that you probably have. Go listen to it.”

Along the lines, in order to be able to do all of that, you must have signed your life away at least 50 times, and there is no choice but that. You can’t be a musician in this day and age and have your music heard without signing your rights away. That’s a really difficult position to be in because we don’t want to sign those rights away, but you kind of have to take it as a risk.

Christopher S. Penn – 10:02
Cost of doing business.

Ruby King – 10:03
Yes, it’s kind of what you have to do. And now — but there never seemed to be anything that was happening that was bad, and now it’s, “Oh, AI has gone, ‘Hi. We stole all of your stuff a while ago because you consented to it, just to be clear. So that’s done now. Thank you. Bye.’” “Oh, okay. Yes, we did sign the things, but we had to. Is it really consent if you are forced to do it?”

Christopher S. Penn – 10:34
So from the perspective then of a musician or any composer, what is — what is your play to ensure that you have a career?

Ruby King – 10:45
Find a different field? I mean, that’s true at the moment, but no. I think it — I know it’s something you say. It was trying to have a personality and being a personality, I think that is a big thing of it. I’m terrified of that. I have accounts on multiple different social media platforms, but they are nothing as me — I am not the profile picture. I can’t do selfies. I look like the polite cat. It just doesn’t work, so I don’t really have them. I happily tweet about other things, but no one needs to know about me. I’m quite happy.

But you need to if you want to be successful because people need to see the behind-the-scenes in order to get as much justification for listening to it, because it could always be — it could be AI, or I could just listen to something else. It’s difficult. But another thing is creativity because, at the moment, AI is doing better. It is throwing in some creativity. However, it’s not always doing it right. So something else that musicians need to do is be themselves, be creative, and sort of think about it from the perspective of a listener. “Would AI do this?” You were saying that it’s sort of statistical.

Christopher S. Penn – 12:10
It’s all probability.

Ruby King – 12:10
Yeah, if it’s all probability, then do against — go against the probability. If your piece feels like it should end, don’t end it. Do a different section. Do a B section, maybe do a C section. Do something else that makes the listener go, “Oh, okay.” Because AI is doing that. But if you do it more, you win.

Christopher S. Penn – 12:30
And then you end up with Scenes from an Italian Restaurant, which is three songs smashed into one.

Ruby King – 12:34
Sure. But it does depend because you do have to be careful because not all creativity is necessarily going to be palatable. You can’t just chuck every single thing you could do musically into one basket and go, “This is not AI, I promise. Listen to it. You will love it.” Because you don’t want to hear a piece that changes key every five minutes, and all the lyrics are really strange, and then it suddenly goes into French, and the tempo changes so many times you’re getting used to it, then suddenly it changes. You’re just going to be, “I don’t — too much is too much.”

Humans have to know when that too much is just for the sake of it. If you want to do that anyway, then that’s fine. But that has to be an intentional choice that I don’t want people to sit here and think, “This is music I’m listening to for fun.” Usually, there are pieces where it’s — it’s a choice that you’re listening to it. That’s perfectly okay.

There’s a piece that’s sort of representing dementia, and it’s — I think it’s about seven hours. It’s a long one. I haven’t sat through it — I would have been very upset if I’d sat through the entirety of that — but it’s a very interesting thing to do with music because it was actually using samples of other older music, ballroom music. So it wasn’t quite the same, but it was doing a lot of compositional aspects with it and changing it to represent the stages of dementia. But to listen to that, it’s more of an art experience.

Ruby King – 13:59
AI might have been able to do it, I suppose, but a human would have had to put a lot of thought into it to go, “And at this stage, humans experience this. So you will do this to the music.” There still would have had to be a lot of humanity behind it to do it. I think that’s by The Caretaker, if anyone wants to look that up. Good luck. It’s very depressing.

Yeah, there’s a lot of different things with that kind of thing. But music, in order to stay ahead of the AI, you’ve got to keep an eye on AI as well. You can’t just go, “AI will do its thing, and I will do mine.” You sort of have to stay up-to-date with what it’s doing. If the voices are better — I mean, if you can play live instruments and add those to your tracks, do so because of the humanity of the stuff will help because AI doesn’t have that right now. So use it as an advantage. Do that. Sing on your pieces if you want lyrics, or have a choir. You can have choir patches, and the choir patches are more realistic than AI choir because they also move at once. It’s more like a chord pack, more synthy, which is fine, but it’s not a choir. So trying to do a church thing, it’s not quite right. I don’t know.

Christopher S. Penn – 15:15
It —

Ruby King – 15:16
It is difficult because it will always be improving. To some extent, I think in the end, if there is no more legal help coming to save us, then it will be more of a case of — it will be down to the ethics and preferences of the people who used to pay you and listen to your music as to whether you can still put food on the table from your music or if that’s even an option in the future. It’s a very sad, unfortunate situation, and I hope it’s not the case, but I do think that is very possibly the way that it is going, especially having seen the way that artists are being treated at the moment. Music was only a bit behind that, and as always, things kind of don’t go the way you want them to.

Christopher S. Penn – 16:07
That’s true.

Ruby King – 16:07
Yeah.

Christopher S. Penn – 16:08
Well, so having — having that AI portion is essentially going to be the mass-produced music, and then you will have the individual artisans who — people follow that musician because of that person and their musical skills. A machine could do probably very similar music, but you’re there for that person specifically. So it is almost building a cult of personality around you as a musician or a composer, etc., so that you have that army of true fans that are willing to support you because of who you are as a human being.

Ruby King – 16:50
And that also comes down to finding your own sound, too. So if you have a preference for the way that you prefer to write music, or music that sounds good to you, then that sort of becomes your sound. And that was true of artists, and then they said, “Oh, do this art in the style of XYZ.” And then it scanned all their art and did that, and that kind of took that out of the water, and it probably will with music, too. It has. If you say “Taylor Swift,” then you get a lot of Taylor Swift-ish music, and that’s only going to improve, probably. Although you said that the data —

Christopher S. Penn – 17:22
Well, so one of the challenges with music, in particular, is there are not actually that many songs. AI needs enormous amounts of data to train on. For example, a text language model needs between seven and ten petabytes of data of raw text to give you a sense of how much data that is. That is a bookshelf that goes around the equator of the planet twice in raw text.

Ruby King – 17:48
Okay, it’s quite big.

Christopher S. Penn – 17:49
Yes, it’s quite large. There aren’t that many songs.

Ruby King – 17:52
No.

Christopher S. Penn – 17:54
So you would have to upsample by essentially repeatedly training a model, “Hey, here’s a song again. Keep learning from it.” Or, in the case of things like music on YouTube, “Here’s the original. Here’s the 18 cover band versions of this song,” so that you can learn the predictable next sound of what should come next.

Ruby King – 18:17
Yeah. Musicians are taught to do the same thing. One of the main things you are taught as a composer starting out is, “Listen to other people’s music. Decide what you like. Decide what you don’t like, and do that. But then try and be creative about the way you do that,” because, obviously, plagiarism is frowned upon. So yeah, if finding a voice is important, but it isn’t going to save you. Finding a voice is hard enough on its own. You would hope that would be enough, but apparently nothing is.

Machine-Generated Transcript

What follows is an AI-generated transcript. The transcript may contain errors and is not a substitute for watching the video.

Christopher S. Penn – 00:00
In this five-part series on music and AI, filmed at the 2024 Marketing AI Conference, or MACON, I sit down with composer Ruby King to discuss AI music and the future of creativity. This is part two, the human touch, imperfections, and intent. Let’s try another piece. We’re going to switch to something theoretically a Viennese waltz.

Ruby King – 00:21
We’ll find out if it actually is or not. That’s okay.

Christopher S. Penn – 01:58
So what was that? How was that?

Ruby King – 02:00
It was very interesting. It was quite nice.

Christopher S. Penn – 02:03
Okay.

Ruby King – 02:04
It was quite nice. The first thing I was noticing was — again, sort of going into “How was this recorded if it was by humans?” — and it sounded like — I could have been wrong because I’m sat away from it — but it sounded like there’s a bit of crackle on the recording.

Christopher S. Penn – 02:16
Interesting.

Ruby King – 02:16
A little bit. I was kind of wondering — it sounded like a recording that my old violin teacher would give me from her cassettes. It was, “This is what the piece you are playing,” and it was recorded a very long time ago in black and white. It’s just the EQ as well. The quality of the sound — it didn’t sound like it was recorded. It didn’t sound like I was in the room with it, and that’s not a bad thing. It’s just — it sounds like older recordings. So I’m wondering if maybe the info it was fed was from past —

Christopher S. Penn – 02:48
— highly likely, yeah.

Ruby King – 02:49
Okay. As to whether it’s a Viennese waltz, I can’t answer that because I don’t have — I can’t be sure enough. I’m not an expert, and someone will shoot me down online if I say one or the other things. I am going to back out of that one slowly.

Christopher S. Penn – 03:02
Okay.

Ruby King – 03:03
But it started faster, and it got — it had some really slow bits in it. That was nice. I was surprised by how many different sections there were that seemed to be trying to do a theme and variation. I’m not completely sure it did do a theme and variation because I think it might have forgotten exactly what it did or the music wasn’t memorable enough to remember. I would have to look at the actual notes themselves and listen to it quite a number of times more. But it sounded like it was attempting to do a theme of variation.

I think waltzes are usually three, four — goes a 1-2-3, 1-2-3. And most of that was, I think one bit seemed to be six, eight, six, eight, or six — my music teacher’s going to kill me — but sort of, where it’s longer: 1-2-3-4-5-6, 1-2-3-4-5-6. So it’s still the same feel, but the phrasing doesn’t stop midway through the bar. It ends at the end, if that makes any sense.

Christopher S. Penn – 04:02
No, it makes total sense.

Ruby King – 04:03
Okay.

Christopher S. Penn – 04:04
But it calls back to how the Transformers model works, where it’s doing things in chunks. Instead of sewing it back together, one of the things that you’ll notice with tools like Suno, particularly for longer compositions, they lose coherence, two and a half, three and a half minutes into the song. Sometimes they’ll just go totally off the rails, and you’re not sure why. But then when you look underneath the hood, “Oh, it’s because it’s doing 32nd chunks, and it either forgot, or there was a token that got misplaced in chunk 13 that just throws the whole thing off.”

Ruby King – 04:39
Yeah, that was — that was enjoyable listening. But another thing that — I’ve done violin for quite a number of years, and one of the key things I was listening to there was, “Is this a real human playing it? Is this playable?” Because one of the main things you can hear in music that’s violin or viola or whatever lead is the bowings. Most people don’t bother about this, which is why I’m insufferable to watch TV with, an Umbrella Academy. When they whip out the violin, I’m, “No!” Because it was a bit loud. Sorry. It was —

Christopher S. Penn – 05:17
— or Sherlock, where he’s not — what he’s doing, the hand motions don’t match the actual audio.

Ruby King – 05:22
It’s just so painful. Just get someone who can, please. We exist. Just the fingers — all the editors mess it up afterwards. I don’t blame them, but, okay, anyways. One of the main things is bowing, and you can hear it because if it’s up and down, you can hear how the string — it sort of — it changes. There’s a break in between the noise. If you’re slurring, which means going from one note to the other with the same bow, it’s only the note that changes. There’s not really a pause in the middle. So most of that was separate bowings, especially when it was doing quite fast jumps. At one point, it was — I pulled a face at one of — one of those face pullings was because it was doing something quite fast with a lot of jumping.

Ruby King – 06:10
Their right hand must have been going — it is very possibly possible, but that player deserves an award.

Christopher S. Penn – 06:21
Probably some aspirin.

Ruby King – 06:24
The way it would be chosen to play it — if the composers specified that would be how you should do it, then you would probably try and do it like that. But a violinist would naturally try and not do that much effort because it doesn’t sound right being so separate either. If it was more together, just in phrases, a few notes in the bar, maybe just — if it’s in three, four, then maybe six of those could have been in one bow and then another six in another bow, and that would have still kept the phrasing. But just the way that it’s performed, it’s not thinking about performance rules. It’s just thinking, “These are the notes, and this is a violin sound. Therefore, this is correct.”

Christopher S. Penn – 07:05
Right. So AI is essentially synthesizing from the outcome of the data but does not understand the techniques used to make the data.

Ruby King – 07:17
Yeah, I think so.

Christopher S. Penn – 07:18
Okay.

Ruby King – 07:19
Because there’s a few times there, I think, in that piece, it would have been nice if there was a slide up because it does do some jumps. The nice thing with the violin is it’s not a piano. I can say that I play both, but on the piano, you can do slides, you can do glissandos, but it’s easier on a violin because you can kind of slide up to a note and add some nice vibrato once you get there. Piano, it’s a bit more — you can’t get all those microtones between. So it’s kind of — because there’s —

Christopher S. Penn – 07:50
— defined intervals between one note. So if you are a content creator using generative AI, the instruments that have more analog between notes, like a violin, as opposed to being more defined segments, it’ll be more of a giveaway that you’re using AI because the machines are not synthesizing the technique needed to create the sound.

Ruby King – 08:13
Yeah. So it is said that the violin, or strings, are the closest thing to the human voice. And the human voice, we can easily tell, most of the time, when it is not a human voice. Okay. Saying that, there’s a lot of speech that is very good now, and you can’t really tell. Those models are very advanced, and it sounds very good. But singing isn’t quite there yet, I’m assuming, because there’s so many different techniques all the way down to breathing and where you hold your head. The sound’s going to be different if you’re looking up to — if you’re looking down. It’s just because there are so many variables.

So the violin and singing — the human voice — are dead giveaways. Well, voice more so than violin, because I think you have to be a bit more trained on violin, usually. But still, it is coming down to the subconscious. When you listen to that, are you thinking, “This is a real performer? I can imagine being sat in a concert hall?” Are you going, “This is a violin. I can’t say anything more about it than that”?

Christopher S. Penn – 09:19
Right. Okay, let’s try a piano piece. So this one is supposedly a ragtime. What’s that sound?

Ruby King – 09:33
Slides in there. It’s gone again. You’d expect the violin to come back in a minute. Just loosen that.

Christopher S. Penn – 10:59
So this is an example where it should have stopped.

Ruby King – 11:05
Unless it’s — ooh. I mean, it should have stopped if that was the intention. But if this was the intention, then that would be an impressive thing for a human to do.

Christopher S. Penn – 11:18
So the prompt on this was just, “Enough beat back then.”

Ruby King – 11:22
It’s just — it liked what it did, and it was, “I’m going to do more before you shut me down. I’m done now.”

Christopher S. Penn – 11:38
Okay, so that was an example, in particular with Suno, where it will have these — they’re almost hallucinations, where it sounds like there’s a logical stop of the song, and it’s, “I’m just going to keep going.”

Ruby King – 11:53
Was it given the time frame it had to be?

Christopher S. Penn – 11:54
No.

Ruby King – 11:55
No. So it just — it was just, “I’m having too much of a fun time here. You cannot stop me.”

Christopher S. Penn – 12:00
If I had to guess, and this is pure speculation, the model had enough fragments of enough tokens leftover to forecast from that it was, “I don’t know if I should stop or not.”

Ruby King – 12:12
Okay. It definitely — it did feel like it came to an end, but it continuing wasn’t necessarily wrong. So it wasn’t right for what you said, but if you were in a concert hall and that was played, and then there was a pause — and sometimes you do that, which is why you’re told, “Do not clap in the middle of a movement because you will look like an idiot, and everyone will stare at you, and the musicians will remember you for the random time you —” true story — then it’s kind of — it sort of felt like a different movement.

Christopher S. Penn – 12:46
Right.

Ruby King – 12:47
It was — the music didn’t necessarily feel connected, but it felt like a nice, different piece. So you might expect, if it was meant to be the same piece, you’d expect the first piece of music to come back again, and that would be sort of a bigger end, and that would be an ABA structure because you sort of have the A, and then the B, then it just ended. It was a nice end, but it wasn’t necessarily the way you’d expect a piece to be. A and B does happen. That is okay, but for the instructions you gave it, you’d expect it to go back to the A section. So it’s not that it’s wrong, it’s just — it’s not — it’s wrong for what you asked it to do.

Ruby King – 13:28
But musically speaking, if you handed that in, it would probably be seen as a good thing that you did something creative, a false end, and then you continued with something that was different, and it was an “Oh!” moment, which is a good thing. So musically, it’s good. Prompt-wise, not so good.

Christopher S. Penn – 13:48
Right. Okay, let’s try one more piece, and then I want to talk about how we can — for people who want to use these tools — how we can get better performance out of them. So this is the last one. This is the ragtime.

Ruby King – 14:20
Good bassline. It’s repeating itself. I remember that — for now. For now. Basic — good — oh, that is a variation of theme A. Oh, that’s definitely theme A. Half speed. Slower. Happy. That is — anyway, I can’t remember theme B well enough, but I remember A — is that key change, or is that just — okay, that’s all right. This is longer than I thought it could be, and it’s remembering itself quite well. You would probably want it to be doing something more exciting with this now because it is just feeling like it’s gone back to the start. The left hand should probably be doing something more interesting. It’s an odd end. I mean, it’s a valid end. It’s not what I would have done, but it — it ends fairly convincingly.

Machine-Generated Transcript

What follows is an AI-generated transcript. The transcript may contain errors and is not a substitute for watching the video.

Christopher S. Penn – 00:01
In this five-part series on music and AI, filmed at the 2024 Marketing AI conference in Macon, I sit down with composer Ruby King to discuss AI music and the future of creativity.

Christopher S. Penn – 00:12
This is part one, defining music in the age of AI.

Christopher S. Penn – 00:17
Alright, so who are you and what do you do?

Ruby King – 00:21
Hello, I am Ruby. I’ve just graduated studying music and music with psychology at the University of Southampton. I specialized in composition and writing music. I play violin, viola, piano, and I sing, although I mostly focus on composing music.

Christopher S. Penn – 00:41
Okay, so I’m sure you’ve seen and heard that generative AI can simulate music. Let me start with this: how do you know what is good music and what is not?

Ruby King – 01:00
The trouble with that question is it’s so subjective that you always come down to the answer that is really very annoying: it depends. It depends on who you are as a person because what I like as music is very different to what you like as music. To be fair, it’s well-covered, but that’s not because what you listen to is bad music. It’s just not the music that I choose to listen to on a regular basis. It stresses me out. I like to listen to slightly more calming things, but that’s not because when I’m listening to yours, I’m thinking, “This is terrible music.”

So it really heavily depends. I suppose when I’m listening, I’m sort of looking for something that makes me want to listen to it — so originality, creativity. If there’s something in a piece that I don’t particularly find terribly interesting, but then suddenly there’s a key change or something that happens, then usually that makes — in your brain, you sort of think — this is more interesting, this is better. So there are lots of different things that can contribute to being good music, but there’s no way to actually say, “This is good and that is bad,” and anyone that tells you otherwise has a very high opinion of themselves.

Christopher S. Penn – 02:17
Okay, well then let’s get even more elementary. What is music?

Ruby King – 02:27
That is such a broad, terrible question that the answer is always, “I’d rather be answering deep philosophical questions than what is music?” Because it means so many different things to different people and different cultures. We can get so bogged down in the western world — “Oh, it’s only music if it’s organized sound in a set way that uses this sort of set scale.” But then you’re completely ignoring other cultures where, when you listen to it, it is absolutely music, and it’s not for us to say it’s not music.

We’re kind of trying to define it by the set rules that we have sort of told ourselves it has to be. So, music is whatever you want it to be. Okay. Just the easiest way to answer it.

Christopher S. Penn – 03:06
Okay, that’s fair. We should probably turn the lights on. Would help. And let’s turn on this one, too, because we have it. We brought it, we may as well use it. You can turn on a party mode.

Ruby King – 03:25
Please don’t.

Christopher S. Penn – 03:26
There we go. That’s better. Yeah. Alright. Look at that lighting. So when it comes to AI, the way that today’s models work — particularly services like Suno and Mubert and stuff like that, and Jukebox — we have more primitive services like AIVA. They are all using a type of model called transformers. What transformers do is they take in a lot of examples and try to say, “Okay, well, what is the next likely thing going to be based on everything that’s occurred so far?” So if you have a sentence, “I pledge allegiance to the,” the next highest probability word in that sentence is going to be “flag”.

It’s unlikely to be “rutabaga”. “Rutabaga” would be an interesting sentence for sure, but it’s not the highest probability by a long shot. And so, when model makers train these models, they basically take in huge amounts of data — typically from YouTube — and they say, “This is what a pop song is, this is what a rap song is, this is what a country music song is.” And therefore, when a user requests a pop song about this, it’s going to go into its knowledge, try to say, “Okay, well, these are the conditions that the user set up — tempo, or major key, or piano and strings — associate those words with the training data it’s had, and then try to assemble what it thinks that would be.” Typically, these services will do this behind the scenes in 32nd increments, and then they stitch it all together.

When we listen to a piece of this synthetic music, it is all high probability, which means that, absent the ability to tune the model yourself, you kind of just have to deal with what you’re given. So let’s listen to an example of a piece of music. This is one that is from — I attempted to make something with the lyrics in Google’s Gemini first, and then use Suno to compose. This is it.

Speaker 4 – 05:51
Empty echoes in the night searching for a human touch in a world that I see.

Christopher S. Penn – 06:04
Like a dream.

Speaker 4 – 06:07
Come no one ever found metrics crumble lose the hole empathy story must be told and the warnings gently died.

Christopher S. Penn – 07:29
Okay, so what did you hear there?

Ruby King – 07:32
Okay, well, first of all, it sounded pretty bland. But when it came in with — rocksteady, I think that was it —

Christopher S. Penn – 07:40
Yeah. Okay.

Ruby King – 07:41
— the first time, it’s one of those times when you go, “Oh, something’s changed,” but it’s not in a bad way, because sometimes when something changes, it’s not something that you’re, “Oh darn, that.” But that was — it kind of had, kind of paused, and then it went off. And that is very different to what AI was doing not too long ago because it wasn’t really doing the, “Oh, hello, wait a minute” kind of things. So when I’m listening to that, I’m listening to the things that change. Because if it’s just — this is because it’s got a — I think it’s a four-bar phrase that then repeats, and that’s very typical of music. That’s what you’re told to do. If you have something you want to be the melody, reuse it. If you don’t reuse it, no one’s going to remember it.

And it’s not something we want to listen to if it’s not repeating itself, at least a little bit, usually. Okay, so with that, it is doing what’s expected to quite a high degree. The qualities of the vocals are a —

Speaker 4 – 08:40
— different question.

Ruby King – 08:43
— especially when it was without words. It doesn’t quite know what to do. It’s an interesting experience, but I’m sure it’ll improve, and that’s not quite the point. The drums are very heavy, and I suppose for the genre, it sounded about right. That’s not my specialty, that particular genre. It’s not one I listen too much to either. But when I am listening, it’s generally the things that — okay, it’s set out that it wants to do this, but in what ways is it going to branch out and make this more interesting for the human listener?

Christopher S. Penn – 09:17
What are those things that make it more interesting to a human listener?

Ruby King – 09:19
Okay, so those can be key changes. That can either be a sudden key change or one that’s kind of built up into — both can be satisfying, but it depends how it’s done. Also, if any time signature changes because that can change the feel of the song, and also, usually the rhythm of the words can just give it a different feel. And that can be interesting, but can also be done badly. All things can be done badly, but if it’s done well, it’s satisfying. Rhythm, tempo — if anything, any changes, really, because a lot of AI can be — and some — a lot of human-written things can be — I have set about, “I like these eight bars. I’m going to use these eight bars again, and then I’m told I have to have a bridge.”

So there’s something I’ve written, and then I’m back to this, and this is by the template. So this is good. It might be, but it always depends how it’s done — if there’s any, what kind of creativity you’ve gone for. Have you explored it? Have you had a go at something and decided it didn’t work and gone with something else? Is there some kind of originality where the listener’s going, “Oh, I like this. This is good.” And even if you don’t know what that is, that’s fine, but it’s still something that is there that the composer, or whatever has written it, has done.

Christopher S. Penn – 10:44
Okay, is that music?

Ruby King – 10:46
I would say that’s music.

Christopher S. Penn – 10:47
Okay, is it good music? Is it technically proficient? Because obviously there’s a difference. I don’t like Indian food, but I can differentiate between technically proficient, prepared Indian food and poorly made. Okay, they both taste bad, but they taste bad in different ways.

Christopher S. Penn – 11:05
Yeah.

Ruby King – 11:08
It’s not great, but it is certainly a lot better than when it was sort of, “Oh, it’s rubbish.” It’s now kind of, “Oh, okay, this could be playing, and someone might notice if the singing was done by a human or in a more satisfying way.” Because I have heard better voices than that if the voice — because the thing is, as humans, we are very good at being able to pick out when something sounds human. So even in an orchestral setting, we’re taught that if you’re going to write music for a TV show or something, or just cinematic music, or with an orchestra, if you’re going to write it on Logic Pro with lots of music samples, then in order to make it sound realistic, you need to manually go through and try and change the level of expression that you have — if it’s an expensive enough kit to do that.

And also, if you have just one violin that’s actually recorded live doing the same line as all the other violins, then the slight bit of human error can fool the human ear into thinking the rest of it is also by humans. I always find that really cool.

Christopher S. Penn – 12:24
Interesting.

Ruby King – 12:25
Yeah.

Christopher S. Penn – 12:26
So if you had, say, a stochastic generator in AI, which is basically a randomness engine that intentionally introduced small errors into what the AI produced, it would be more convincing to the human ear.

Ruby King – 12:41
Yeah. So in Logic Pro itself, you have — when you’ve got the drum generator or any kind of thing — you can go into the tempo bit, flux tempo — I can’t remember the exact. I think it’s flux time or something. And there is a setting where you can — I can’t remember if it’s called swing or if it’s — it’s something along on the left-hand side where you can drag it along, and it will just set stuff off ever so slightly from the exact beat it’s meant to be on. Because if you tell it to do the exact beat, it’s correct, but it’s not how a human would play it. Not because we’re terrible at music, it’s —

Christopher S. Penn – 13:15
— just because it’s so precise that it can only be machine-made.

Ruby King – 13:18
Yeah. When you hear a metronome, it’s not someone behind it all —

Christopher S. Penn – 13:21
— going —

Ruby King – 13:24
— it’s a machine, whether that be a mechanical one or a computer doing that for you, and that’s fine. And we use those to stay in time with them, and that’s perfectly fine. But if you want something to be human — when on a violin, it’s more obvious on a violin than it is on a piano, maybe, because on the violin, there’s a lot more slides between notes and things you can do there. Vibrato. Sometimes string scratches, although they’re not always intended, the sound of them makes you think, “Oh, but this is real. This is actually being performed.” Because so much of music in television, especially because there’s barely any budget for the actors, let alone the music, so much of it is just, “Here’s a bunch of stock libraries, do the best you can.”

So by just putting in a little bit of human stuff into it and making the EQ and reverb sound like it’s in a concert hall and ordering the things in a way that you’re used to hearing it, all of these things can contribute to making it sound more human. And I think if AI starts going into trying to actually make it sound like it is human or having the voice sung by someone else, or just little bits changed, it would start sounding a lot less like it’s packaged off the Tesco shelves or Walmart. I don’t know.

Christopher S. Penn – 14:47
It’s interesting, though, because you’re saying in many ways that the imperfections define humanity.

Ruby King – 14:54
Yeah, because we’re not perfect, but music isn’t designed to be perfect. There are so many different things about music, so many different ways that you can do things. When you are writing it, you write it in a way that you enjoy, but it’s not necessarily a way that other people will enjoy. And sometimes you can add imperfections on purpose, and that becomes part of the piece. So long as you say it’s intentional, then you get away with it.

Christopher S. Penn – 15:20
Okay. But a machine can’t just make random mistakes.

Ruby King – 15:28
No.

Christopher S. Penn – 15:30
So how do you make random, not random mistakes?

Ruby King – 15:36
I suppose it helps if you say that the mistakes can’t be huge ones.

Christopher S. Penn – 15:40
Okay.

Ruby King – 15:41
If the singer’s just going way off-key, then I will shut my laptop and throw it across, and I win. But no one wants to hear that. That’s not —

Christopher S. Penn – 15:50
It’s like the people at drunk karaoke — “Wow, that’s awful. Someone should tear gas these people.”

Ruby King – 15:56
Yeah. It’s sort of — within reason. If you go to a concert from an artist you love and they start singing terribly, you aren’t going to be there, “Oh, but it’s the person I love. It’s all great and fine.” You’re going to be, “Why aren’t they putting effort in for the show I’ve come to see? I know they can do better than this. Are they actually just auto-tuning themselves the whole time? I feel really let down.” So there’s — we do have auto-tune, and that is used so much.

Christopher S. Penn – 16:27
Hence why the machine voice sounds like that.

Ruby King – 16:30
The machine sounds worse because, with auto-tune, it’s still a human inputting it. But that kind of sounds like two people put together in a blender screaming. It sounds like there’s two different lines at the same time but still the same person, and it’s just really confusing listening to it. How can — because you’re always trying to — you’re sort of trained to go, “Okay, well, how is this recorded?” And with that, you’re kind of going, “I have no idea how they managed to make that sound unless it was just put through a machine that was intended to make this noise.” So it doesn’t sound realistic at all. But a lot of people don’t care about that.

But then it’s still subconscious that when you hear stuff — there have been psychological studies — when you hear stuff that isn’t right or isn’t human, then you kind of know anyway, whether it matters to you or not. It’s still in the back of your mind that you can kind of recognize that.

Christopher S. Penn – 17:30
Okay, that concludes part one.
