ABSTRACT:
The organ is designed to play six-tone musical scales, which lead naturally to a simple and easily learned system of hexatonic notation. A scale selector apparatus can be set to make different hexatonic scales playable on the front digitals of the keyboard. For most advantageous use of the instrument, music should be written in or translated into hexatonic notation. The instrument can also be used to play conventionally written music, by using the scale selector apparatus to translate into the conventional diatonic scale.
A hexatonic scale selector switch operates on the top octave of tones; lower tones are derived from the top octave by means of chains of frequency dividers. The association of tones with digitals will be correct in lower octaves of the keyboard, provided that all the musical scales have the same number of tones per octave. For translation to the diatonic scale, it is necessary to use a second scale selector switch operating on the outputs from the chains of frequency dividers.
