for a plurality of sound systems (any sources, components and loud-speakers)
The first performance included electronic circuitry, microphones, radio, tape and a television set. The materials consist of a page with a straight line and 2 transparencies. The first transparency contains 12 short straight lines an 38 triangles. The other tranparency contains 57 short bisected lines (90 degrees) and 114 half circles with diameters. The triangles represent loudspeakers, the bisected lines represent components (exclusive of mixers, triggering devices, antennas etc. Inclusive of amplifiers, pre-amps, modulators and filters) and the half circles indicate the sound sources. The lines are used for the placement of the sound sources. By cutting up all needed lines and symbols and superimposing these elements a program can be obtained.
