Soundings is a 36 foot long sculpture
made up of three layers of Plexiglas. The front layer
would be partially mirrorized and behind are two layers
of Plexiglas with images of a wooden chair on them. Different
lights behind the sheets of Plexiglas would vary in intensity
based upon the amount of sound in the room and backlight
the images so they would be visible through the mirror.
Robbie Robinson brought in Fred Waldhauer,
who had designed the proportional control system for 9
Evenings, and I suggested they consult Cecil Coker, a
scientist who was working in speech analysis at the Labs.
Waldhauer, Coker and Rauschenberg got together and decided
the sound would be divided into four frequency bands,
so that a high-pitched voice or sound would trigger a
different set of lights from a low-pitched voice or sound;
that is, children would trigger different lights from
adults standing beside them.
