Original Wikitext content:
=The Bohlen-Pierce scale= The Bohlen-Pierce scale is a [[nonoctave]] scale, a 13-part equal division of the perfect-twelfth (3/1). Each step is about 146 ¢, making it a [[macrotonal]] scale. It was discovered independently by Heinz Bohlen, John Pierce, Kees van Prooijen, and perhaps others, usually noticed for its good approximation of odd-number just ratios 3:5, 5:7, 3:7, etc. [[http://members.aol.com/bpsite/|Bohlen Pierce website]] [[http://en.wikipedia.org/wiki/Bohlen-Pierce_scale|Wikipedia Bohlen-Pierce scale]] ==Physical instruments tuned to the BP scale== Guitar Clarinets Metallophone Electronic Organ ==Compositions== Links to avaliable music written in BP at [[http://members.aol.com/bpsite/references2.html#anchor81501|above website]].
