DrumPiano play online

This DrumPiano (Piano Band with Drums aka PianoBand) Music app is very special to me. When i planned to do this app, i was thinking about kid and one thing i keep it in mind that, for this age, she should be interested to play the key notes. My small research about this key notes like "Do, Re, Mi, Fa, Sol, La, Ti, Do" and also i have added collection of drums music when you hit the different color. I hope, kids may like this app and enjoy the music.

Suppose if you find any key notes is wrong, please feel free to give me your feedback as well as if you have that key, please send to me.
