ABSTRACT:
An electrically-keyed musical instrument has a double-row keyboard in which back digitals alternate with front digitals throughout the keyboard. The keyboard is provided with two sets of landmarks to assist playing from either the traditional notation or a six-tone notation. The musical instrument has an electronic key signature actuator apparatus which may be set to physically actuate any key signature of music written in the traditional notation, so that the diatonic tones in the selected key can be played entirely on the front digitals of the keyboard. The other five tones of the chromatic scale must be played on back digitals of the keyboard. The electronic apparatus also allows the front digitals to play the whole-tone scale or a hexachord scale, and to play the hexachord scale in any selected one of twelve different hexachord keys. A person trained on the instrument in a six-tone notation can, by throwing a switch, easily play music written in the traditional notation. Furthermore, the musical instrument can be used by musicians trained in the traditional system to play music written in the traditional notation, or by throwing a switch, in the six-tone notation.
