Pendulum Music

Reich came up with the concept while working at the University of Colorado. He was swinging a live microphone in the style of the cowboy’s lasso, and noting the produced feedback, he composed for an “orchestra” of microphones.Three or more microphones are suspended above the speakers by means of a cable and stand. The microphones are pulled back, switched on, and released over the speaker, and gravity causes them to swing back and forth as pendulums. As the microphone nears the speaker, a feedback tone is created. Different lengths of cable will swing at different speeds, creating an overlapping series of feedback squeals. The music created is thus the result of the process of the swinging microphones.

Five screens were installed by the artist as pendulums that swing continuously. As soon as all five have come to a standstill, they are pulled back into their original positions with the help of cable winches and are made to swing again – triggered by pulling a rip cord, a performative act that cannot take place without human intervention and which involves the exhibition supervisor in the installation. Each cycle, which lasts approximately 45 minutes, ends as soon as all five screens have come to a standstill and no more sound is produced by their movement. The sound is produced by the amplification of the friction to which the joints of the moving pendulum are subjected. Multiplication thus creates five oscillating loops that merge into one another with a time offset.
