context_page_description: A hydraulophone is a tonal acoustic musical instrument played by direct physical contact with water where sound is generated or affected hydraulically. The hydraulophone was described and named by Steve Mann in 2005, and patented in 2011. Typically, sound is produced by the same hydraulic fluid in contact with the player's fingers. It has been used as a sensory exploration device for low-vision individuals.
context_section_description: As public art installations, hydraulophones can be made in various themes and designs.
  An example of a theme-specific hydraulophone is the Aquatune located at the main entrance to the Legoland waterpark in Carlsbad California.  This hydraulophone, which Legoland describes as "a musical water stand", is the centerpiece of the entranceway, and is flanked on either side by educational installation exhibits, such as water tables where participants can build water dams from lego blocks, and learn about laminar and turbulent flows through various flow channels.
