The Bohlen Pierce scale page coming soon!
The Bohlen Pierce scale is a 13-step non octave scale which is tempered to the 3/1. This curious fretting hits odd harmonics from the harmonic series similar to dominant sounding chords with 3:5:7, 5:7:9, and when extended to 39-steps microtonally 3:5:7:9:11:13:15 and so forth. The scales original properties were first discovered by Heinz Bohlen and John Pierce, and the triple-BP's properties by Paul Erlich. This guitar was unveiled at the very first Bohlen-Pierce Symposium in Boston, MA March 8-10 2010, held at North Eastern Conservatory and Berklee College of Music.
