Musical variations from a chaotic mapping [PDF]
Chaos: An Interdisciplinary Journal of Nonlinear Science, 1996 A chaotic mapping provides a technique for generating musical variations of an original work. This technique, based on the sensitivity of chaotic trajectories to initial conditions, produces changes in the pitch sequence of a piece. A sequence of musical pitches {pi}, i.e., any piece ranging from Bach (or earlier) to contemporary music, is paired with ...
