The Bohlen-Pierce scale
November 11, 2006 12:46 PM Subscribe
The Bohlen-Pierce scale is a musical scale which has thirteen notes spread evenly across one and a half octaves, so that the highest note is three times the frequency of the lowest. Compare with the western twelve-tone scale, which has twelve notes spread evenly across one octave, where the highest note is twice the frequency of the lowest. Both are tempered scales, and both have close approximations to 'just intonations', meaning you could play the scales by plucking a string clamped at certain ratios like 1/2, 1/4, 5/3, etc. One of the independant co-inventors of the scale, John Pierce, was also a famous electrical engineer best known for inventing the communications satellite. You can listen to Pachelbel's Canon(midi link) rewritten in this scale.
