EMIC - Compositional experiments and real-time mapping issues in performance

This paper discusses the development of a gestural controller interface for contemporary vocal performance and electronic processing called the eMic (extended Mic-stand interface controller). This instrument is a modified microphone stand, custom fitted with an array of sensors and gesture capturing devices aimed at capturing commonly used gestures and movements of vocal performers who use microphones and microphone stands in performance. These common gestures were discussed in an earlier paper prepared for the New Interfaces for Musical Expression Conference 2003 (Hewitt and Stevenson 2003) and it was seen that the gestures form the basis of a well-practiced language and social code for communication between performers and audiences. The microphone itself has become a performance tool of the contemporary vocalist and a means for extending the voice as an instrument. The eMic aims to further facilitate the performer by giving them more flexibility and control over the processing and sound of their voice in a live context. This paper explores the mapping process, early compositional experiments and the use of the eMic in live performance, identifying the successes and shortcomings of the interface and areas for possible exploration and further development.
