Protozoo

(1997)
Live Stereo Sound Processing
WP: CCRMA 11th Annual Industrial Affiliates Meeting, May 21-23, 1997, Stanford.

Protozoo is a real-time, generative composition that creates a sequential, variative form solely as a result of a system of few basic audio processing operations. As such, it forms an acoustical analogon to dynamical systems often found in phenomena like chemical reactions, population growth, or models of processes in ecosystems. The listener is presented with a “zoo” of acoustical pre- and near-“life forms”, simplistic, yet complex organisms, some of which develop to be more stable than others. Biological concepts like activation, inhibition, growth and death, transformation, digestion, inheritance and evolution come to mind and are helpful for the understanding of the composition.

Realizations of Protozoo may be either in the form of a sound installation, an interactive instrument (using MIDI controllers), or as an effects processor.

Melodies

Melodies is a composition in-between a sound installation and concert piece. It consists of four musically rather underdetermined layers that are distributed across the concert hall to play back in different sub-spaces. The listener, who may roam the hall freely throughout the performance, is thus at any time presented with an acoustic situation where foreground, middleground and background interact vaguely to form a continuously evolving set of melodic fragments that is dependent only on his position within the hall.

Polyptichon

(1996)
String Quartet, 2:30 min

A short and grotesque “central composition” for string quartet. In the middle of the piece, Polyptichon exposes a rapid sequence of five, extremely different musical "tableaus" on the backdrop of an extended, centrifugal double-stop glissando in the second violin. The short composition is "kicked off" by two cracking noises in the first violin, framing an introductory 30'' silence.
