Trumpet note/fingering learning tool

Welcome.

I've made this tool help people like my son and me, who have trouble learning notes and fingerings. I have no formal musical training, except for 4 years of trombone in my youth — needless to say, I would love your feedback! If you want to contribute, the source code can be found here, on github. Music notation is generated by the awesome VexFlow package.
Changing any of the above settings will reset all learning progress
