Fractal geometry of music.

Abstract: Music critics have compared Bach's music to the precision of mathematics. What "mathematics" and what "precision" are the questions for a curious scientist. The purpose of this short note is to suggest that the mathematics is, at least in part, Mandelbrot's fractal geometry and the precision is the deviation from a log-og linear plot.Music until the 17th century was one ofthe four mathematical disciplines of the quadrivium beside arithmetic, geometry, and astronomy. The cause of consonance, in terms of Aristot… Show more

“…Su and Wu [27] applied Hurst exponent and Fourier analysis in sequences of musical notes and noted that music shares similar fractal properties with the fractional Brownian motion. Properties of self-similarity, regarding the acoustic frequency of the signals, were observed in [14], where aspects of fractal geometry were studied. Given this previous evidence of fractal properties in music, such as the fractional Brownian motion, the use of fractal and multifractal dimension for genre classification, and evidences of self-similarity properties found on musical tones, we wish to further explore whether multiscale fractal analysis could manifest supplementary facts about the structure of music signals, taking into account that such methods 1 The term 'fractal' was coined by Mandelbrot from the Latin word fractus, meaning "broken", to describe objects that are irregular (or "fragmented") to fit within the traditional geometry [16].…”

“…Among her noteworthy collaborators were evolutionary biologist Stephen Jay Gould, physicist Roger Penrose, and mathematician Benoit Mandelbrot, whose fractal geometry had by then emerged as the go-to analogy for understanding principles of self-similarity in the new age of complexity. In response to a paper called The Fractal Geometry of Music (Hsu and Hsu 1990), in which a series of fractal metaphors were suggested to exist in the music of Bach, Tureck penned a detailed response nearly as long as the FIgure 12.4 Musical analogy. The musical analogy is among the most enduring of conceptual models for architecture.…”
