live algorithm which interacts with an improvising human performer

Instrumentation
laptop, microphone
Programme Note

chor-respondent is a computer program that interacts with a live performer. The interaction is managed purely through sound, there is no complicated MIDI equipment or electronic sensors – just a microphone. chor-respondent listens to the sounds that the performer plays, and responds by producing sounds of its own. It builds up chords based on the performer’s recent notes, and any notes that it is currently playing. The result is swelling chords of beautiful but often unexpected harmony. A performance lasts as long as the live improviser wishes.

The program had its first performance at the Songs for Dynamic Systems concert organized by the Live Algorithms for Music network. The performance was with Finn Peters on flute, at Café Oto in London, August 6th 2009.
