a motion sensetive accordion for the iPhone

This iPhone application is inspired by accordions. Using the iPhone's built in accelerometer, the user controls the overall amplitude of sounds by swaying back and forth with the iPhone, simulating the motion used to play a mechanical accorion. The sounds are all synthesized with pure tones, but given the motion-controled amplitude envelopes, sound quite rich. The key layout provides four common chords (I, IV, V, and V7) and one octave of an A Major scale.
