ABSTRACT:
An electronic digital type organ having one or more keyboards generating two or more harmonically related tones in response to keying a melody monophonically on one of the keyboards. The harmonic tones may be of different tonal quality, so as to produce the effect of different instruments. The harmonic tones are generated automatically at a pitch determined by either the next lowest note to the accompaniment notes played on another keyboard or, if no other key is depressed, a pitch that is determined by the melody note and stored half-tone interval information.
