The scare is over and the enjoyable can start. That’s how I have a tendency to think about artistic endeavors involving synthetic intelligence lately. We’ve moved previous, I believe, hyperbolic claims about AI making human artwork redundant and may now get pleasure from all the chances this expertise affords. In that mild, Shadow Planet — a brand new album made as a three-way collaboration between two people and AI — exhibits precisely what kind enjoyable may be had.
Shadow Planet is the creation of author Robin Sloan, musician Jesse Solomon Clark, and Jukebox, a machine studying music program made by OpenAI. After a casual Instagram dialog between Sloan and Clark about beginning a band (named The Cotton Modules), the 2 started exchanging tapes of music. A seasoned composer, Clark despatched seeds of songs to Sloan who fed them into Jukebox, which is skilled on an enormous dataset of 1.2 million songs and tries to autocomplete any audio it hears. The AI program, steered by Sloan, then constructed on Clark’s concepts, which Sloan despatched again to him to develop additional.
OpenAI’s Jukebox mannequin is skilled on 1.2 million songs to provide its personal music
The top results of this three-way commerce is Shadow Planet, an atmospheric album during which snippets of folks songs and digital hooks emerge like moss-covered logs from a fuzzy lavatory of ambient loops and disintegrating samples. It’s a full album in and of itself: a pocket musical universe to discover.
As Sloan defined to me in an interview over e mail, the sound of Shadow Planet is in some ways a results of the constraints of Jukebox, which solely outputs mono audio at 44.1kHz. “Making this album, I discovered that this sort of AI mannequin is completely an ‘instrument’ you’ll want to study to play,” he instructed me. “It’s mainly a tuba! A really… unusual… and highly effective… tuba…”
It’s this form of emergent creativity, when machines and people reply to limitations and benefits in each other’s programming, that makes AI artwork so fascinating. Take into consideration how the evolution of the harpsichord to the piano affected kinds of music, for instance, and because the potential of the latter to play loudly or softly (fairly than the one mounted dynamic of the harpsichord) engendered new musical genres. This, I believe, is what’s occurring now with an entire vary of AI fashions which are shaping artistic output.
You possibly can learn my interview with Sloan beneath, and discover out why working with machine studying felt to him “like wandering in an unlimited labyrinth.” And you’ll take heed to Shadow Planet on Spotify, Apple Music, iTunes, Bandcamp, or on Sloan and Clark’s web site.

Hey Robin, thanks for taking the time to talk to me about this album. Initially, inform me slightly bit please about what materials Jesse was sending you to begin this collaboration? Was it authentic songs?
Sure! Jesse is a composer for commercials, movies, and bodily installations — he wrote the generative soundtrack that runs contained in the customer middle at Amazon’s Spheres in Seattle, yikes. So he’s well-accustomed to sitting down and producing a bunch of musical choices. Every tape I obtained from him had round a dozen small “songlets” on it, some solely 20-30 seconds lengthy, others a couple of minutes, all completely different, all separated by a little bit of silence. So, my first job was at all times to hear by way of, resolve what I favored greatest, and replica that to the pc.
And then you definately fed these into an AI system. Are you able to inform me slightly bit about that program? What was it and the way does it work?
I used OpenAI’s Jukebox mannequin, which they skilled on ~1.2 million songs, 600K of them in English; it operates on uncooked audio samples. That’s an enormous a part of the enchantment for me; I discover the MIDI-centric AI methods too… well mannered? They respect the grid an excessive amount of! The sample-based methods (which I’ve used earlier than, in several incarnations, together with to make music for the audiobook of my final novel) are crunchier and extra unstable, so I like them higher.
To pattern the Jukebox mannequin, I used my very own custom-made code. The approach OpenAI describes of their publication could be very very like, “Hey, Jukebox, play me a music that feels like The Beatles,” however I wished to have the ability to “bizarre it up,” so my sampling code permits me to specify many alternative artists and genres and interpolate between them, even when they don’t have something in frequent.
“It was, to be sincere, a particularly sluggish and annoying course of”
And that’s all simply the setup. The sampling course of itself is interactive. I’d at all times begin with a “seed” from one in every of Jesse’s tapes, which might give the mannequin a path, a vibe to observe. In essence, I’d say to the mannequin: “I’d like one thing that’s a mixture of style X and Y, form of like artists A and B, but in addition, it’s bought to observe this introduction: <Jesse’s music performs>”
I’d additionally, in some instances, specify lyrics. Then, I might go about eight to 10 seconds at a time, producing three choices at every step — the pc churns for 5 to 10 minutes, FUN — then play them again, choose one, and proceed forward… or generally reject all three and begin over. In the long run, I’d have a pattern between 60-90 seconds lengthy, and I’d print that to tape.
It was, to be sincere, a particularly sluggish and annoying course of, however the outcomes have been so fascinating and evocative that I used to be at all times motivated to maintain going!
What did Jesse take into consideration the fabric you have been sending him?
He underscores that working with the fabric was typically VERY troublesome. Bizarre devices would stand up out of nowhere, or the important thing would change in a wierd method, and many others. However I believe that was a part of the enjoyable, too, and the explanation to do that undertaking in any respect: every pattern I despatched him was a puzzle to resolve.
In the end, his work was each responsive — “how do I help this pattern, assist it shine” — and transformative — “what sort of music ought to this be?” That’s evident on all of the songs, however a transparent instance is “Magnet Prepare,” the place Jesse took pains to showcase and help the vocal efficiency (bizarre and dorky and nice) after which prolonged it with parts that recommend “train-ness” — the chugging percussion, and many others.
And the way precisely did you hone in on this explicit sound, do you suppose? What pushed you on this path?
Oh, it was undoubtedly the grain of the medium. Early on, I instructed Jesse that though the mannequin may produce sound at 44.1kHz, it was solely in mono. His response was: “Cool! Let’s use mono cassettes then.” And the music he despatched again to me was mono, as effectively. In his ultimate manufacturing cross, he added a little bit of stereo width, simply so the songs weren’t all completely locked within the middle, but it surely’s a reasonably “slim” album usually, and that’s completely due to the AI’s limitation, which we determined to embrace and lengthen fairly than battle. Identical goes for the lo-fi, grainy, “radio tuned to a ghost channel” sound — completely an artifact of the best way the mannequin produces music, which we amplified additional by bouncing the music to tape so many instances.
So, within the completed songs that we’re listening to, what quantity of the music is made by AI and what by human? Is it even doable to make that distinction?
It actually does range extensively from music to music, and the reality is, in some instances, we misplaced monitor! I’d begin with a phrase from Jesse, put it by way of my sampling course of, ship it again to him, he’d add a layer or lengthen it, ship it again to me, I’d put it BACK by way of the sampling course of… what’s the human / AI breakdown there? It’s all form of blended and layered collectively.
There’s one division that’s clear: anytime you hear something that feels like a human voice, whether or not it’s enunciating lyrics clearly or form of ooh-ing and ahh-ing, that voice is generated by the AI.
“this sort of AI mannequin is completely an ‘instrument’ you’ll want to study to play”
Making this album, I discovered that this sort of AI mannequin is completely an “instrument” you’ll want to study to play. And I’ve come to consider that analogy is much more helpful and generative than like, “AI co-composer” or “automated AI artist” or no matter different analogy you might need heard or can think about. It’s mainly a tuba! A really… unusual… and highly effective… tuba…
Haha, proper! I’ve spoken to fairly a number of artists who use machine studying fashions to make songs or books, and so they typically speak concerning the dynamic between them and the AI — whether or not it was pushing them in a given path, for instance. Did it really feel like this for you in any respect, if you have been exploring what music Jukebox may offer you?
I really like this query, and right here’s why: beforehand, I’ve been fairly skeptical / vital of the “large [AI] fashions skilled on all the pieces,” whilst they’ve risen to prominence. It is a class that features GPT-3, Jukebox, CLIP, VQGAN, and many others. It’s very clear that this method produces highly effective outcomes, however I at all times thought it was extra creatively fascinating to take accountability to your personal dataset, perceive its composition as a key artistic determination, and many others. And I nonetheless suppose that’s true, to a level…
BUT!
“it has felt like wandering in an unlimited labyrinth or a lifeless metropolis”
The expertise of utilizing Jukebox actually turned me round on this. For me, it has felt like wandering in an unlimited labyrinth or a lifeless metropolis: big, stuffed with alleys and arcades. Even now, having used it for thus lengthy, I don’t know what’s nonetheless ready in there, what may be discovered and carried out. Clearly, I’m betraying the truth that I’ve performed too many RPGs right here… however really! That’s the sensation, and it’s VERY enjoyable.
With that in thoughts, then, what do you suppose making this album with Jesse taught you about the way forward for AI and creativity? What do you suppose these methods will likely be doing sooner or later?
AI strategies can do an entire bunch of various issues for various sorts of artists, in fact, however concerning this particular class, the generative mannequin that may produce new music, new sounds. It appears TOTALLY clear to me that these are on the trail to turning into a brand new form of synthesizer or electrical guitar. I believe the story will likely be broadly related — they’ll go from analysis undertaking to novelty (which is the place we’re at now) to instruments for nascent virtuosos (it’s thrilling to consider attending to that time!) to commonplace contributors in any / each studio.
