Sisters Sisters was composed for two dancers and interactive computer music system. Both dancers wear a DIEM Digital Dance Interface. The computer uses the data to control synthesis parameters. Software was designed by the composer using the MAX MSP digital synthesis programming environment. About fifty sound files are contained in the computer’s RAM and these sound files are played back and altered in real time using comb filter and resonance filter algorithms. The dancers control playback and filter parameters in various ways during the course of the piece, but there are no prerecorded sequences or tracks. All of the sounds heard in the piece are produced as a direct reaction to the dancer’s movements. Each dancers controls four different sounds with her elbows and knees. In some cases, the samples are looped and activity levels of the elbows and knees are used to increases the volumes of the sounds: the more the dancer moves, the more sound is heard. In other cases the elbows and knees are used to control “scrub” functions in much the same way that a tape can be slowly scrubbed forward and backward over a tape head to create fast and slow playback both forward and backward. For example, when a dancer moves her arm from straight to bent a short sample will be played back. When the dancer moves the same elbow from the bent position to straight, the same sound will be played back backwards. Which sounds will be controlled by the dancers elbows and knees and how they are controlled changes during the course of the piece. In addition, the sounds are processed in real time by the computer to create tonal material out of recorded noise-like sounds such as water, fire, wind, breaking stones and wood, scraping gravel, etc. The choreography for Sisters was created first by Marie Brolin-Tani and the music was created to fit the choreography. The composer’s task was to create software that would produce sounds to accompany the choreography. When rehearsals began, both the music and the choreography were gradually developed and changed.
