I think you could definitely do the same thing to learn relative pitch. In western music theory there's generally only 12 notes. And #1 and #12 are the same, an octave, which many people can recognize implicitly
Furthermore, while a piano might have 88 keys (still doable with practice) most actual music rarely jumps more than an octave or two.
Generally, music is also further restricted to a key/mode of 8 notes, again with 1 and 8 being the octave, which you probably already know
If I were to teach myself again, I would first find a reference for the intervals 1-8 in a major key and in a minor key. Or learn the full 12 at once if that's more sensible to you. For example the main theme from "Jaws" is a minor 2nd (2/12. Or the song for Happy Birthday (in the USA) starts with a major 2nd (3/12). I had a few more examples, but this Wikipedia article seems to have far better information than I could give you

You could also just try to listen to music, possibly at half or quarter speed (easy to do on YouTube), and try to write down the notes, and checking your answers, I'm sure that could work.
I've used the emulator "Retroarch" on the Steam Deck and had good success playing with it in offline mode. It has a bit of a learning curve, but it's been a great fit for me
When I did this a number of years ago, and it was only around 5-6GB, or about 20GB with all the images. I also added about 4GB for windows, android, iOS, Linux, and Mac OS apps to parse/view the data. All of that fits on a 32GB flashdrive that I used to keep on my keychain but currently is in my glove compartment I think.
It sparks some amazement in me still to wrap my head around the reality of so much information in a thing the size of my pinky. Or the size of my pinky nail if you use a micro SD card. And yeah, just took a weekend of downloading and setting it up, and flashdrives/microsd cards are easily found at department stores, or even gas stations sometimes.
Even disregarded any potential doomsday utility, the amusement/amazement it's brought me was well worth the modest time/money it took. I hope more people give it a try
I'm a novice at machine learning, but Open AI made a python library for reinforcement learning in video games, and a fork of it is still actively maintained [1]. It's been a few years, but I remember being able to get it up and running in a day or two (maybe a weekend). It used the Retroarch emulator, which is compatible with a huge number of emulators and consoles.
I encourage you to give it a try! I feel that video games are a bit underrated by current AI buzz, I think there's lots of potential for a machine to learn a skill through playing a game. And lots of potential for a game being selected or even created with the goal of teaching a specific skill. However at that point maybe it's better to forego the audio and visuals and speak to the machine in text or with pure data.
On the other hand, I have seen a video about convolutional neural networks that feed on each pixel of an image. So perhaps training with sound data, or with the pixels of a spectrogram, could have some positive results. And certainly I would be amused to see a game played in time with music, or possibly even dancing with a songs melody, harmony, and story as well.
Anything that's ever been created by humans, existed first in the imagination of a human brain. And you've got one of those. A mental vision pursued and brought from the mind into physical reality is a beautiful thing, a gift for all of humanity in my eyes. I think it's quite worthwhile. But that's just my perspective. Thank you for sharing your imagination. Have a nice day
The landing page doesn't seem very exciting (on mobile at least) but the "practice" area of the site contains quite a few web apps to demonstrate the concepts. I think the basic idea is that western music uses 12 tones, and chromatone gives each of those tones a color, and uses those 12 color/tone pairs as a basis for teaching music theory in a visual way.
And also here's where I found a lot of additional web apps. I'll look through them more when I'm at my PC. But just thought I'd post these here for anyone who clicked on the hn link but was underwhelmed or confused by the landing page:
