Genesis on iPhone's PianoStudio

"http://frontierdesign.com/PianoStudio

A demo of "The Lamb Lies Down On Broadway" by Genesis and played on PianoStudio on an iPhone.

Featuring a unique and truly playable interface designed specifically for the iPhone, PianoStudio lets you compose and perform complex songs that are impossible to play with other apps that limit you to tiny keyboards with limited ranges.
PianoStudio is the first piano app for the iPhone and iPod touch that helps you explore musical ideas, learn songs, write your own tunes, and even play along with your iTunes music.
By placing individual notes, entire chords, and even complete musical phrases onto a set of buttons that you can arrange and play, you can write and perform real piano music with chord progressions, "two-handed" patterns, and melodies in Allegro, all right on your iPhone or iPod touch."

Update via in the comments:

"In fact, the clavinet was not invented to become a funky instrument. First it was more a kind of a substitution for a spinett. I have made a video, where you can hear the original sound and also the funky sound with a wahwah.
