'moon' is taken from the forthcoming album 'biophilia'.
the 'moon' app is a musical sequencer that explores the similarities between the cycles of the moon and tides with sequences in music. change the phase of the moon to control the number of notes, and change the phase of the pearls to alter their pitch.
