A sound installation with a pendulum of seven steel spheres, electronics and seven loudspeakers.
The pendulum motion depends on the touch of the audience. It creates complex rhythm patterns which repeat and gently transform until the pendulum stands still again.
The impulses between the spheres of the pendulum are tracked with contact microphones and translated into software triggers. "Repetition Is Change" is a mechanical looper, a complex metronome which gradually morphs its patterns over time. The sounds are spatialized with seven loudspeakers, one for each sphere of the pendulum. The patterns are programmed in scales of pre-recorded samples in the computer and played live by the movement of the pendulum.
Currently in development, this is a prototype with which I create the compositions and sound design. The premiere will take place at the festival Heiderauschen in Uelzen, Nothern Germany in July 2021. Metal works by Christoph Gunsenheimer, electronics by elektrobuero, software add-ons by Leo Hofmann.
"Repetition is Change" first prototype
first prototype of the pendulum sound installation "Repetition is Change" by Andi Otto. The steel spheres will be equipped with contact microphones which allow for a signal tracking of the impulses. The signals trigger snippets of recorded sound which will be spatialized with seven speakers, one speaker for each sphere.
