The sculpture incorporates carved stone and marble columns salvaged from the 19th-century Laurel Hill Cemetery after its relocation.
The 25 pipes are connected to an underground chamber where the water movement is amplified.
Acoustic output depends entirely on tidal movement, meaning the 'performance' varies based on the lunar cycle and bay current strength.
The project was initiated by artists Peter Richards and George Gonzales as part of the Exploratorium’s public art program.
It is technically classified as an aeolian harp, though it is powered by water rather than wind.
The Wave Organ is a wave-activated acoustic sculpture situated on a jetty in the San Francisco Bay. Built in 1986 by the Exploratorium and artist Peter Richards, the structure utilizes 25 PVC pipes of varying lengths to capture the sounds of the tides. As water rises and falls, it pushes air and water through these submerged pipes, creating gurgling, rumbling, and whistling sounds. The sculpture is constructed using salvaged materials from the demolished Laurel Hill Cemetery, including carved granite and marble blocks. It serves as both a functional scientific instrument and a public art installation. Visitors can listen to the auditory effects by sitting on the stone steps adjacent to the pipes. The site is located at the tip of a man-made jetty extending into the bay, providing views of the Golden Gate Bridge and the San Francisco skyline.

Visit during high tide to ensure the pipes are sufficiently submerged for optimal acoustic activity.
Bring a windbreaker, as the jetty is fully exposed to bay gusts and cold air.
Check local tide charts online before your visit to ensure the water level is rising or falling significantly.
Do not visit during dead low tide, as the lack of water movement renders the sculpture silent.
Avoid climbing on the delicate PVC pipe structures; maintain a quiet demeanor to hear the subtle acoustic sounds.
