Similar things:

* Csound standard numeric scores -- https://csound.com/docs/manual/ScoreTop.html

* CsBeats (alternative score language for Csound) -- https://csound.com/docs/manual/CsBeats.html

Hey, the idea is nice, It would be great to know what pushed you to start this format.

Also, any apps that uses it would benefit from being add to the repo assuring usability in addition to readibility.

I like the idea overall. Looks like something that would be fun to combine with music programming languages (SuperCollider/Of etc).

Not so sure how human-friendly the fractional beats are? Is that something that people more into music than I am are comfortable with? I would have expected something like MIDIs "24 ticks per quarter note" instead. And a format like bar.beat.tick. Maybe just because that is what I am used to.

How does this compare to standard ABC? More capable, presumably, but a comparison would be useful.

I think that for completeness it needs looping and conditional constructs

pretty cool!

Probably stating the obvious here, but this would be a good way for an LLM to attempt to write or modify music.
