The Corpus Callosum
The Corpus Callosum is an occasional journal of armchair musings, by a suburban, reality-based, slightly-left-of-center guy, who reserves the right to be highly irregular at times. Topics: social commentary, neuroscience, politics, science news. Mission: to develop connections between hard science and social science, using linear thinking and intuition; and to explore the relative merits of spontaneity vs. strategy.

Subharmonics and Nonharmonic Overtones (and hubcaps)
Category: Armchair Musings
Posted on: July 12, 2006 7:40 AM, by Joseph j7uy5
Samuel Gaudet and Claude Gauthier, mathematicians at the University of Moncton in New Brunswick, have developed the tritare. This is like a guitar, but the strings branch in a Y-shape. This results in the production of nonharmonic overtones, something typically heard only from percussion instruments.
Meanwhile, at NYU, violinist Mari Kimura has figured out how to produce subharmonics with her traditional acoustic instrument. This enables her to play cello-like notes, an octave below what one ordinarily hears from a violin.
She says she doesn't really know how she does it, but physicists are trying to figure it out.
Sound clips of the tritare are here. Clips of Ms. Kimura's subharmonics are here. You can but her CD, The World Below G, here.
All this reminds me of a performance at last year's Edgefest at Kerrytown. Michael G. Nastos played the hubcaps. Music to my ears. Clips are at Sublingual's Myspace page.
Progress is being made on the perceptual science of music, but we still do not understand why people like to do strange things with noise.
