In an exceptional melding of man and machine, Dan Tepfer uses the Yamaha Disklavier CFX piano to bring together his world-class pianism with his background in physics and programming. As he improvises, the piano responds in real time with notes of its own, the keys of the keyboard depressing themselves as if by magic. For different pieces, the pianist has programmed a variety of approaches for how the Disklavier responses are constructed, leading to unique sonic signatures for each.
