Despite being rather simplistic, it's a damn good concept. I've never played an instrument before and can tap out a half-decent Jingle Bells in a few minutes, and it's quite good fun. I'm sure it would be even easier if it had more features like a metronome. It's a bit of a shame the guy doesn't get VC money and a proper development team together to develop the product, because I think it really is the future of learning to play the piano.
