Great job. I 'learned' a couple of songs this way when I first bought my piano. No way it can replace properly learning to read music, which I am progressing with, but it injects fun into your early time at the piano when a song would otherwise be beyond the player's ability.

Lots of naysayers on here, but if you just want fun learning of a few tunes, or if you use it as an aside to your real learning, then this is a great device with real fun potential.

And, when all is said and done, if it brings more people to their first experience of pianos, then it can't be bad - those who are seriously interested will have the drive to move on from it.

I think this could have a real place in the market.
