Small Music Keyboard (WIP)

A little keyboard I did. I just wanted to do a keyboard app as simple as possible for dummies like me to use. I want to add more instruments and the notes are wrong at the moment the A B notes are on the lower octave than the G before. I will try and sort this out though. Also I want to add some features to help in learning to play by ear as well.

This seems to work in "Brave" browser but doesn't work in Firefox.
