Temporal Interference

Temporal Interference

This project was a collaboration with Jane Franklin Dance that explores the concept of space and the interference created through the motion of bodies near a sensor. Three dancers interact with the sensor device – a Theremin – suspended on stage. The Theremin is not used to create the sound for this piece, instead I use it to detect the proximity of the dancers. The signal from the Theremin is converted to MIDI data and drives a synthesizer as well as controls aspects of the video. The entire piece is more than 20 minutes and is divided into 5 sections. The second and fourth section include music composed by Gina Biver.

The dancers moving between the antennae of the Theremin create radio interference, which differs based on their proximity to the antenne. I used this information to program distortions in the projected image and alter the frequency of the sounds during the live performance. The sounds range from violin music recorded by Gina Biver, to electronic synthesized audio. Each performance was unique and created an interested choreography where the dancers influenced the outcome. This work has been performed in gallery spaces in Washington DC, the Kennedy Center Millenium stage and at Performatica in Pueblas, Mexico. A short clip from the middle section can be seen below:
