Kees van Prooijen

Kees (Cornelis) van Prooijen (born 7 August 1952) is a creator of computer art.^[1] Although it does not bear his name, he independently discovered the Bohlen–Pierce scale,^[2][3] a non-octave-repeating scale based on the tritave and spectra containing odd harmonics, in 1978. Van Prooijen came across the scale through an investigation of continued fractions.^[4][5][6]

He also invented the Kees height, or an "expressibility" measure for complexity of just intonation pitch classes.^[7][8]
