Swinging Pendulum

Suspended from automated grids, more than 400 pendulums are activated to initiate a sweeping 15 part counterpoint of tempi, spacial juxtaposition and gradients of centrifugal force which offers the spectator a constantly morphing labyrinth of significant complexity. The spectators
are free to attempt a navigation this statistically unpredictable environment, but are requested to avoid coming in contact with any of the swinging pendulums. This task, which automatically initiates and alerts the spectators innate predictive faculties, produces a lively choreography of manifold and intricate avoidance strategies.

Gravity harp
Este instrumento fue diseñado por Andy Cavatorta, encargado de hacer robots musicales en el MIT Media Lab. Se ocuparon 4 pendulos de once cuerdas cada uno para hacer esta arpa gravitacional. Hay un software que controla la rotación de cada péndulo y determina la nota que suena dependiendo de su posición dentro del balance del instrumento. El sonido de este instrumento se puede escuchar en la canción de “Solstice”.

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.
