Fletcher, Neville H.2020-11-041835-212Xhttp://hdl.handle.net/1885/213600Western music is based upon the sounds of instruments with repeating waveforms and harmonic frequency spectra. While strings and pipes come close to this ideal, they achieve it only because of the influence of great levels of nonlinearity in the sound generating mechanism. Bells and gongs, on the other hand, generally have very inharmonic spectra, and when significant nonlinearity is present it leads to phenomena such as pitch glide, frequency-multiplication cascades, and transition to chaos.application/pdfen-AU© 2000 Australian Institute of Physics2000
