Musical fountain show is a type of entertainment-oriented fountain that creates an aesthetic design (including three-dimensional images). A musical fountain is achieved by employing the effects of timed sound waves and timed light. This kind fountain usually can be a large scale, using hundreds of water jets and lights. Musical features tend to be complex, and require a degree of mechanical, hydraulic, electrical, and electronic components out of view that might be as impressive to its audience as the show itself.
