Check out the work of Richard Voss who quite some time ago (late 70's) showed the relation of noise, formally construed, to music. There's a Scientific American article on it in 80's. A good book on it is Schroeder's "Chaos, Fractals, Power Laws". The analysis involves formal definitions of Brownian motion (brown noise), white noise, and 1/f noise Fourier spectra ("pink" noise"). Mozart and "real" music is characterised by profiles with 1/f spectra (pink noise). The natural world is full of such colored noise. ^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^ Paul Treffner, PhD Motor Coordination & Dynamics Laboratory School of Physiotherapy & Exercise Science Griffith University, Gold Coast Campus PMB 50, Gold Coast Mail Centre QLD 9726, Australia tel. +61 7 5552 8215 fax: +61 7 5552 8674 p.treffner(at)
