Play piano online

I'm putting this under 'assistive devices' because it really is a way to do something that a paralyzed person might not be able to do otherwise. There are probably other programs out there, and they may even be better, but this one works and I like it.

This is a very short piano keyboard. A person could spend many happy hours picking out tunes, learning to read music, or composing original songs, just with this simple online piano keyboard.
