Abstract
An electronic musical instrument by which a performer can provide a musical accompaniment in different musical harmonies by playing on a standard keyboard. The performer adjusts a tempo clock in order to determine the period of the rhythmic beat of the accompaniment. The instrument enables the performer to change to a different harmony at the end of a beat (e.g., by changing his hand position on the keyboard) without interrupting the continuity of the accompaniment and to hear much of the subsequent beat in the changed harmony even if his hand does not complete the change to the new harmony position until a portion of the subsequent beat has elapsed.
