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]
