This would be really cool if I knew how to read tabs lol

I can think of a few improvements that could be fun to see;

- visual indicator for chord progression

- timing/tempo/click track for practice

- play the chord via audio output

- verify the chord via audio input

On a higher level, this is the sort of app/experience that really opens up learning to a whole new audience, particularly if there's no easy or affordable access to instructors. Nicely done!
