D... C.... B... Ok, got it. I think I'm ready to play this https://www.youtube.com/watch?v=f2GfgNpX2QA But seriously, did you create a your own textual notation or is this based on some existing standard? Either way it's pretty cool :)

Haha :D Nah this is quite standard I believe, I just wanted to codify the things I've learned so far: these three notes :D See e.g. https://www.justforwinds.com/skins/quill/just_for_winds/assets/images/site/charts/flute-fingering-chart.jpg or https://www.youtube.com/watch?v=ONPPF02UrJo

Now all you need is an animated version that takes midi input.

Haha, that would be fun indeed :D
