this is nice. Where can I learn more about music theory? I have a project (is stopped right now) where I use JavaScript to create music as well, but I don't know jack about music.

I used excerpts from that code on my Genius game, where I give the player audio feedback from each move (I think is do re mi fa).

"Intervals", "Scales", and "Chords" are good terms to search for. They are elementary concepts present in a lot of music. Ten Steps use six notes of the C Major Scale, all of which belong to either the I or IV chord. The I and IV chords use, by definition, an interval of 1-4-7.

For an entertaining overview, check out Leonard Bernstein's 1973 Norton lectures, "The Unanswered Question"[0]

Nice, I've used an image like this one as guide: https://qph.fs.quoracdn.net/main-qimg-378ba2572d2033b70ef10d... each note om my game is a sine wave with the hertz described in this picture (i randomly choose the rage between 500 - 700, but I don't know what that means).

On my other project, I'm planning on doing like a small "synthesizer" that can play a note "c, d, e f..." and the use it to try and create music, using procedural generation and machine learning.

Anyways, I'll look into what you told me and I'll watch the video. Thanks a lot.
