Outward Hearing (2005) began as an exploration of microtonal clusters with an analog synthesizer (Emu) that does not maintain perfect tunings. The drifting tunings created a phasing dense chord, which were then manipulated by feeding the signal back on itself. The uncertain tuning of the piece is catalyzed by bells, which by nature tend to have indefinite tunings and rich overtones. A recurring motive throughout is the appearance of a voice. The recording of this voice is played back through the Emu and developed as part of the formal structure of the work. stereo tape
