Close Approximation for Solo Voice and Electronics, 2009.
In Close Approximation the means of vocal production are reduced by stricture to the class of phonemes known as fricatives. These phonemes sound as a function of turbulent airflow and are best described by stochastic models-- in other words, they can be characterized as variously filtered noise. The performer is asked to elaborate various scenarios in which his or her vocalizations are either passed unprocessed or halted based on analysis performed on the mic input, evincing a process by which he or she negotiates a threshold by means of highly constrained improvisation. As artifacts of this process, the incursions of electronically generated noise vie for prominence over the expressively filtered and enveloped noise of the performer.
