The Bohlen-Pierce clarinet project was initialised by prof. Georg Hajdu at Hochschule für Musik und Theater Hamburg. The Bohlen-Pierce clarinet (BP clarinet) uses an alternative harmonic scale and was first built in 2007 by the Canadian clarinetist and woodwind maker Stephen Fox, Toronto.

TBPlogo010he Bohlen-Pierce scale (BP scale) was discovered in the 1970s and 1980s by three persons independently from each other. The first one to investigate the scale was the German microwave and communication engineer Heinz Bohlen in Hamburg. Several years later, another microwave and communication electronics engineer, John Robinson Pierce, found the same scale in California, USA. Also, the Dutch software engineer Kees van Prooijen worked on the same stuff.

In difference to the traditional western music scale which is based on the octave, divided into 12 more or less even steps, the Bohlen-Pierce scale uses the duodecime as its returning interval, dividing it into 13 steps, according to various mathematical considerations. The result is an alternative harmonic system that opens new possibilities to contemporary and futuristic music.

In March 2008, the Bohlen Pierce clarinet was premiered by Stephen Fox and Tilly Kooyman (Ensemble tranSpectra) in Guelph, Canada. The pieces „Wanderer“ and „Calypso“ for two BP clarinets were performed.

The very first concert in Europe presenting Bohlen-Pierce clarinets, with a program containing works by Hamburg composers, took place on 13th June 2008 in Hamburg Germany. The interpreters were, amongst others, the clarinetists Anna Bardeli and Nora-Louise Müller. Pieces were by Hajdu, Hamel, Lemke, Stahnke, Schwenk).
