Hidden Voices explores vocal resonance and the musicality of a gong, a primordium and the Doepfer A-100. It attempts to draw the “voice” out of some of the non-vocal sources used, intermingling these with the human voice. The piece plays with spatiality between the five channels, creating an eerie sonic space in which all is not as it sounds. Various editing techniques were used to transform the materials, although many were preserved closely from their original recordings, transformed through their re-contextualization within the structure of the piece. In the first section there is a call-and-response arrangement between the channels, particularly between the front and back left and right channels, with the centre channel emphasizing key gestures and high-frequency content extracted from the other four channels. In the second section this call and response continues on a micro-structural level, within multi-channel gestures. Where the first section is very lush, the second is sparser, foregrounding individual “voices”.
