I'm proud to announce the first international symposium on the Bohlen-Pierce scale. This scale was discovered independently by Heinz Bohlen, Kees van Prooijen and John Pierce in the 1970's and 80's and has some "lucky" properties making this scale increasingly interesting to composers, theorists, mathematicians, cognitive psychologists and instrument makers alike. Recently, a Bohlen-Pierce clarinet was constructed in Canada by Stephen Fox, for which a growing body of compositions is being written. There are five professional clarinetists in Canada, Germany and the USA regularly performing on this instrument. Other acoustic Bohlen-Pierce instruments include recorder, guitar, pan flute, metallophone and a non-standard string instrument called the Stredici built by Toronto architect David Lieberman.

The participants of the symposium include the finest representatives in the field of computer music and microtonality, Max Mathews, Curtis Roads, Clarence Barlow, Richard Boulanger, Larry Polansky, Manfred Stahnke, Paul Erlich among them, as well as Heinz Bohlen himself.

There will be lectures, presentations and concerts on three days in four locations at Northeastern University, New England Conservatory, Berklee College of Music and Goethe Institute.
