Harmonic Rhythm Cycle - Polyrhythms with pitches following harmonic series...

The idea is that each number of beats per measure is assigned a pitch, so e.g. 7 beats to the measure corresponds to the seventh harmonic, 5 beats to the measure corresponds to the fifth and so on. The results sound harmoniously together as they use pitches from the harmonic series. This idea is related to the Lambdoma arrangement of pitches, and to Theremin’s Rhythmicon. Originally suggested by Barbara Hero and may be of interest for music therapy. You can play this in Bounce Metronome Pro at any tempo.
