Pneuma

 

1987 • 9 minutes • solo accordion and real time computer music instrument

 

Pneuma was composed with the intent of giving the performer the greatest possible freedom in interacting with the electro-acoustic accompaniment, while still keeping that accompaniment 'composed'.

This was accomplished by using a Yamaha CX5M computer music instrument which is 'performed' by the player through a footswitch attached to one of the computer's joystick ports.

The performer triggers various sections of the score at his discretion, allowing for exact synchronization without the use of a stopwatch.

At various points in the work real time stochastic processes are employed by the computer, which 'improvises' along with the performer.

 

Pneuma was commissioned by Joseph Petric with the assistance of the Ontario Arts Council.
