Even the best musicians do not play rhythms with perfect precision. Slight variations from an ideal beat pattern are a fundamental characteristic of music played by humans. In this public lecture, using techniques from statistical physics and chaos theory, Prof. Geisel will discuss the laws underlying rhythmic fluctuations and their role in musical perception. With acoustic demostrations and musical examples ranging from J. S. Bach The Art of Fugue to stochastic music, he will highlight the role of long-range correlations in music and its connection to information processing in the brain. One application of these findings is a “humanizing algorithm” which allow computer-performed music to sound more human.

Theo Geisel is director emeritus of the Max Planck Institute for Dynamics and Self-Organization and founder of the Bernstein Center for Computational Neuroscience in Göttingen. Trained as a theoretical physicist and well known for his research on nonlinear and chaotic systems, he has worked in fields that include quantum chaos, the spread of epidemics, and theoretical brain research and was recognized with the Leibniz Prize.  As a student, he showed similar versatility, sometimes neglecting his studies in favor of the saxophone and flute and performing in styles ranging from avant-garde jazz to renaissance music.
