The Harpsichord-Viola is a portable instrument that can be worn with leather straps fastened to the back of the sound box. Once it is worn, the player ties his foot to a lever and begins to walk, providing power to a complex motor apparatus.
Inside the soundbox, because of the movement of the player's leg, a horsehair, or more simply a continuous tape, moves nonstop, and the musician with both hands free can perform polyphonic music pieces for several voices.
