Play tones using buttons as a small keyboard.

I'm making a small keyboard for the kids to play with. It can play tones from c7 to C8, with auto record, and a button for playback.

Timing on playbacks may need some work.

Hey me and my friend try to make this keyboard but we can seem to make the piezo stop from buzzing all the time. It is not reproducing notes but simply a constant high pitch. Can you suggest some change in the code? (we checked the circuit accurately and it is all in the right place) thank you
