Piano Trainer: Sight-Reading Flash Cards

Reading music and playing music are two different skills, and it is entirely possible to be decent at one and hopeless at the other. I wanted something that drilled only the join between them: see a note on the staff, find it on the keyboard. No lessons, no songs, no scoring system to game. Just flash cards.

So I built one. It runs in a browser, it works on a phone, and it is free. Check it out!
