Kees (Cornelis) van Prooijen (born 7 August 1952) is a creator of computer art .[ 1] Bohlen-Pierce scale ,[ 2] [ 3] 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]
