It's kind of ok, but..
Good points: The notes were correct. The font was sophisticated which matched the theme. 's about it, really.
Bad points: There were no sharp/flat keys (black keys). It's not really a piano without all the correct keys! Also, the 'Begin' button didn't work, so had to take advantage of the fact you'd left the right-click menu in there (which I prefer to avoid doing) and click "Forward" to even get to the 'piano'.
Improve on the bad stuff I mentioned and include some kind of tool that lets you move across the octaves and it will be better!
