...but why is it so complicated? A novice interpretation of "music" is "a bunch of notes!" ... my amateur interpretation of "music" is "layers of notes".You can either spam 100 notes in a row, or you effectively end up with:
melody = [ a, b, [c+d], e, ... ]
bassline = [ b, _, b, _, ... ]
music = melody + bassline
score = [
"a bunch of helper text",
+ melody,
+ bassline,
+ page_size, etc...
]
...so Lilypond basically made "Tex4Music", and the format serves a few dual purposes:Engraving! Basically "typesetting" the music for human eyeballs (ie: `*.ly` => `*.pdf`).
Rendering! Basically "playing" the music for human ears (ie: `*.ly` => `*.mid`)
Librarification! Basically, if your music format has "variables" and "for-loops", you can end up with an end score that's something like: `song = [ intro + chorus + bridge + chorus + outro ]`, and then not have to chase down and modify all the places you use `chorus` when you modify it. (See this answer for more precision: https://music.stackexchange.com/a/130894 )
...now imagine doing all of the above for multiple instruments and parceling out `guitar.pdf`, `bass.pdf`, `drums.pdf` and `whole-song.pdf`
TL;DR: Music is haaard, and a lot closer to programming than you think!
