The Wave Organ

The Wave Organ is a sculpture constructed on the shore of San Francisco Bay in May 1986 by the Exploratorium. Through a series of pipes, the Wave Organ interacts with the waves of the bay and conveys their sound to listeners at several different stations. The effects produced vary depending on the level of the tide but include rumbles, gurgles, sloshes, hisses, and other more typical wave sounds. The structure incorporates stone platforms and benches where visitors may sit near the mouths of pipes, listening.
