The instrument is designed to play a six tone scale on its lower digitals, which leads naturally to a simple and easily learned system of music notation. In the preferred embodiment, the six tone scale consists of the first six tones of the conventional diatonic scale, which is called the hexachord scale. For most advantageous use of the instrument, music should be written in or translated into the hexachord notation, but the improved instrument can also be used to play conventionally written music. The hardware to make this possible includes a scale selector switch to translate from a hexachord scale into the conventional diatonic scale. An absolute pitch selector switch is provided, to allow the player to control absolute pitch of the musical output independently of the written music.
