The Wave Organ is a wave-activated sound sculpture located at the end of a jetty in the San Francisco Bay. It was created by artist Peter Richards and master stonemason George Gonzalez in 1986.

The installation is an unlikely sight: a collection of curbstones and cemetery stones that appear in the Bay like an ancient ruin or a strange dream. In this unusual place of discovery and contemplation, the musical phenomenon is only part of the point.

In this audio slideshow, Peter Richards, now a senior artist at the Exploratorium, shares his inspiration for creating this piece and explores its function as a theater in which many different kinds of human experiences unfold.
