AUTOMATIC CHORD AND RHYTHM SYSTEM FOR ELECTRONIC ORGAN

摘要

ABSTRACT OF THE DISCLOSUREThe present system provides an automatic chordaccompaniment and/or an automatic rhythm system, actuation ofonly one left hand operated key producing proper distribution ofroot, third, fifth and seventh parts of a chord and root andfifth parts of a bass line. The bass and/or chord notes maybe automatically rhythmically pulsed or selectively convertedto a continuous mode, while the chord notes may be rhythmicallypulsed to simultaneously sound different accompaniment instru-ments, such as guitar, piano, banjo, etc., at different rhythmicintervals, a touch bar being provided to select a minor chordwhen desired. A set of musical key selector buttons is pro-vided which automatically provides seventh chords in correctpositions for a given key selection. One or more accompanimentinstruments may play different rhythmic sequences when seventhchords are sounded, while actuation of two or more keys, simul-taneously, defeats the chord and bass accompaniment.
