One day I can't wait to have a set of stairs that do this. Then I'll invite my friends over and we'll all play songs together. But only really good songs. That's right no "Thong Song" on my stairway piano! No sir or maam! Though depending on the difficulty of the song I might need a lot of friends. Hmmmm . . . Actually when you have a piano stairway you'll probably have more friends than you know what to do with.
