MelodyMorph is an interface for constructing melodies and making improvised music. It removes a constraint of traditional musical instruments: a fixed mapping between space and pitch. What if you blew up the piano so you could put the keys anywhere you want? With MelodyMorph you can create a customized musical instrument, unique to the piece of music, the player, or the moment.
