The Harmonic Generator is a new experimental electronic instrument. It consists of five main components. First, 64 piano strings chromatically tuned to 32 notes. Second, 32 corresponding motors with 1/2 bristle paint brushes beating the strings at controlled speeds. Third, a keyboard, played like a piano, controlling the motors. Fourth, 12 pick-ups that focus on one octave of strings. Finally, a transducer at the end of the instrument that feed back the sound of the pick-ups into the resonance hull. So far, the result of this new instrument can only be described as a symphony inside the belly of a whale.
