Below you can see the piano waterfall. In the waterfall you can turn tracks on and off, change the speed, pitch, put the song on loop and maximize the piano waterfall.

If you have a midi keyboard, you can connect it to your computer and play along with the song, noting the mistakes and hits of notes.
