Abstract
A pedal teaching system for an electronic musical instrument, specifically an electronic organ. In the rehearse mode of operation the system rhythmically energizes selected ones of a plurality of lights mounted above the pedal clavier to illustrate which pedals form a bass note accompaniment routine for a specific group of keys depressed by the organist and automatically sounds the bass note routine. In the perform mode of operation the system rhythmically energizes selected ones of the plurality of lights to illustrate which pedals form the bass note accompaniment routine and disables the automatic bass note musical output routine so that the organist must physically depress the actual pedals to provide the bass note accompaniment. In a non-rhythmic or static rehearse mode of operation the system iluminates the root bass pedal light corresponding to the chord played on the organ or the bass pedal light corresponding to the lowest frequency being depressed on the organ; and, automatically sounds the appropriate bass note. In a non-rhythmic or static perform mode the system only illuminates the appropriate pedal light.
