Multichannel Endangered Guitar Works generally consist of two independent voices simultaneously drawn from the hybrid interactive guitar/software instrument. In realtime created and processed from guitar manipulations, sounds are distributed to a single voice located somewhere in the room, and to a micropolyphonic/polyrhythmic pattern on the speakers surrounding the audience.
Basic Configuration: Center Speaker In The Middle
Issue Project Room 2005: 16 Speakers On The Ceiling, 1 Speaker In Back
FAMU/Prague 2011: Mono Speaker High Up Behind The Audience
HfMT Hamburg 2012: Wavefield Synthesis System
In regular multichannel systems sounds are still heard as coming from the direction of the speakers. Not so in Wavefield Synthesis Systems, here sounds are perceived as moving in space independently of the speakers, e.g. they can stop in front of your face, and travel slowly through your head. It is possible in Wavefield Synthesis Systems to move mutliple sources independently of each other in the space, however, to preserve the clarity of the spatialization I opted for just moving the mono voice around, while fixing the micropolyphonic/polyrhrythmic pattern on the four walls of the room.
Any configuration that allows for special placement of a single speaker could work. A performance can take place in any space, but works better in spaces that are not necessarily set up as a traditional concert space (such as churches, cellars, circular spaces, caves, etc).
