Abstract: Manually operable control apparatus for an electrical musical instrument such as an electronic organ having automatic chord circuitry which includes a plurality of spaced apart individually operable chord switches less in number than the number of chords available on the organ and connected to the chord circuitry of the organ through a multi-position gang selector switch arranged for a preselected different combination of chords at each of the different positions thereof. The chord switches permit individually activating any one of the individual chords in each of the preselected combination for each of the different positions of the gang selector switch.
