Shown: a detail image of Partch's Chromelodeon, a keyboard instrument with six octaves, and 43 tones to each microtonal octave. This instrument can be directly tied to the ideas of Johannes Itten, whose book on color theory, The Art of Color, defined contemporary color theory. Itten was a Swiss Expressionist painter, designer, teacher, writer and theorist, associated with the Bauhaus. Partch notated the micro-tonal intervals between sounds on the Chromelodeon using a color coded system, related to tones.
Partch's Harmonic Canon II shown above, and below, was 6' wide, and built by Partch in 1953.
My favorite Partch instrument, below: the Cloud Chamber Bowls, made from old nuclear physics lab equipment.
