Fluctuare is an interactive work for flute and computer in eight channels. The work may also be presented in four channels. Musical gestures on the flute are transformed through computer processing – just intonation and microtonal transposition and harmonization, delays, granularization – and octophonic sound spatialization creating a complex texture of multiple flute sonorities surrounding the audience. Instead of amplifying the flute, the microphone is used to bring the listener closer to the flute, revealing more of the subtle breath sounds and shifts in timbre. The composer participates in the performance by the controlling the live processing at the computer.
Fluctuare was composed for and is dedicated to Robert Aitken who premièred the work in the Happening Festival of New Music and Media in Calgary.
