Silent Percussion
File Festival
The “Silent Percussion Project” (SPP) consists in building a set of computer musical instruments that use human gestures to control sounds, composing and performing with them in an attempt to re-incorporate the body in music performance practice. The “SPP” is a response to the question: what kinds of musical instruments does live computer music performance need? To answer this question it researches the aesthetic qualities and language of non-live electronic music, action-perception systems and new media theory to experiment new ways of bridging between gesture and sound. In that sense, the “SPP” looks to address the problem of sound control by introducing new sensing techniques that take advantage of our sensorimotor capabilities. The Silent Drum and MANO instruments analyze shapes made by hands and transform them into multiple streams of continuous data. These streams, or variables, are directly applied to sound control, avoiding the key paradigm. Continuous data is analyzed to extract discrete features of the signals. The variables resulting from analysis are interdependent, that is, changes in one result in changes in the others, creating complex systems that the performer learns by experimentation.
