Musical fountain

A musical fountain, also known as a fairy fountain, prismatic fountain or dancing fountain, is a type of choreographed fountain that creates aesthetic designs as a form of entertainment. The displays are commonly synchronised to music and also feature lighting effects that are refracted and reflected by the moving water. Contemporary multimedia fountains can include lasers, video projection and three-dimensional imagery.

Installations can be large scale, employing hundreds of water jets and lights, and costing into the millions of dollars. Techniques tend to be complex, and require mechanical, hydraulic, electrical, and electronic components that are usually kept out of view.
