The Third Sydney M. Friedberg Lecture in Music and Psychology 1:00pm Leakin Hall Peabody Conservatory Composing and Performing Computer Music with Non-Linear Systems Chris Chafe The lecture will describe methods for composition, synthesis and control of synthesizers using non-linear techniques. In recent work, vortex-like noise and non-linear models have been used to simulate a flute's breath noise and switching air jet. The same computer algorithms can be modified to provide interesting patterns on different levels. Examples will demonstrate their use in composing and performing in real time.
