These were the pieces that I used to feed into the ChucK scripts - four orchestral excertps for solo cello and two selections from the randomly chosen nature file. One selection I chose was a snippet of bird song from around the 10th minute in the file, and a moment of talking from the beginning of the file while they were setting up.
These reflect the individual tracks of the final version of the piece.
In "scoring" the piece I open and close with amplitude-tracked (clarinet) excerpts of the nature sounds. In the case of the bird calls, which open the piece, I staggered the nature sound and the computer generated sound so the ear could process it more easily. Between those two sections are the cello excerpts played with their computer-generated counterparts, fading in and out, overlapping.
