Heinz Bohlen
Heinz P. Bohlen (26 June 1935 – 2 February 2016[citation needed])[1][2] was a microwave electronics and communications engineer.
He designed and described numerous non-octave musical scales (alternative musical tunings and temperaments), many based on combination tones, including the Bohlen–Pierce scale in 1972 (independently discovered by John R. Pierce in 1984, also a microwave electronics and communications engineer, six years later and Kees van Prooijen in 1978),[3] the A12 scale, and the 833 cents scale.
Bohlen began to question and investigate tunings in the early 1970s when a friend and graduate student at the Hamburg Hochschule für Musik und Theater asked him to begin recording concerts at the school. Bohlen asked students why all their music used twelve-tone equal temperament, including the octave, and, dissatisfied with the answers, began to investigate alternate tunings.[1]
