ABSTRACT:
A keyboard input such as the lower manual of an organ includes a plurality of keys covering one or more octaves. A plurality of note sources are provided which can produce the essential notes required for open harmony presentation of the various chords of a guitar and are grouped to represent one set of notes for each guitar string. Preferential switching relays provide re-structuring of conventional close harmony chords into open harmony, and have windings connected in circuit by switches coupled to keys and connect the essential notes for a chord in each group to an output line. The output lines are connected to a sequence timer which transmits the outputs to an audio circuit to produce a synthesized strumming sound output and in open harmony in the same manner as the guitar instrument.
