"David Birchfield. 2004. Composing the digital rainstick. In Proceedings of the 12th annual ACM international conference on Multimedia (MULTIMEDIA '04). ACM, New York, NY, USA, 524-527. DOI=10.1145/1027527.1027655 http://doi.acm.org/10.1145/1027527.1027655" This paper describes work on a composed instrument, the digital rainstick. The instrument is an acoustic rainstick that is augmented by five sensors that send real time performance data to the computer. A generative mechanism creates sound outputs that extend the sonic and expressive means of the rainstick, while collaborating with the performer to generate a compelling musical form that unfolds over the duration of the piece. The design and implementation of the hardware and software tools are first described, followed by a discussion of the results of this work.
