Re: Why the music is music and the noise is noise?

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.
