ABSTRACT:
A musical pitch control for each of the strings on a musical instrument. A pivot arm is secured to one end of each string. Controlled current is applied to a length of memory wire secured between the arm and an anchor point. The bending strain on the arm is sensed and circuitry responsive to the sensor is arranged to rock the arm to maintain a desired tension on the string. A second biasing device also acts upon the arm in opposition to the alloy wire to urge the wire alloy to return to its original condition when no current is flowing through the memory wire.
