NOTE: This app has been renamed to Piano Maestro.
The O’Connor Music Studio has a copy of this app if you (or your student) would like to try it during a lesson.
I see great potential with this app and think it could be useful for you at home.
It’s a fun game that can be used with a piano, the iPad or it can be hooked up to an electric keyboard
