Commotion + Contingence

This section of David Birnbaum's blog presents two data-glove style DMIs created by David - Commotion + Contingence. Commotion is a drum track sequencer type instrument and Contingence is an FM synthesis controller providing a pentatonic scale. A head mounted camera is positioned in front of the mouth to monitor the mouth's shape (and possibly some other things to do with the tongue) and is used to control a delay effect. The instruments are designed to be able to produce sound texture pieces rather than pieces based on melody, harmony and rhythm. The page includes details of both instruments as well as a recording of the only composition to be written for the instruments named Alignment. Also included is an interview (non-technical) with David Birnbaum in which he gives a small demonstration of the instruments and briefly describes how to play them.
