This application relates to various stepped pitch instruments crafted to a novel musical tuning system for the generated frequencies. As such, the tone selection devices are arranged to a distinct set of interval specifications when compared to the tone selection devices for a prior art instrument craft ed to sound the common frequencies of 12 tone equal temperament. To generate th e bicameral tones, the preferred tuning system utilizes two different series o f Pythagorean perfect fifths separated by a known reference interval. Relative to 12 tone, the instant tuning system is primarily concerned with improving the sour major and minor thirds and perfecting the slightly flat fifths. Substantially fewer tones per octave are used than the number required by standard just intonation. Various modifications to existing prior art instruments are described, as well as a novel enharmonic multitone keyboard.
