This started out when I vibe-coded a guitar scale fingering generator. It came out pretty good, and I started adding stuff to it: chords, then how chords and scales interact.Then I added charts for other instruments I mess around with: piano, cello, alto recorder.There's a complexity toggle to go from basic harmony to extended/experimental stuff.It's honestly still mostly a toy, but I thought other people might be interested in playing with it. Source is on github, so it's easy enough to run locally and fork.https://github.com/aleshh/gtr-scales
