A fountain control system capable of synchronizing a water, light, and sound performance. The fountain control system includes a plurality of variable speed pumps which are used to control the flow of water through the discharge conduits and ultimately the height of the stream of water projected by the discharge outlet. The fountain control system is capable of varying the speed of the pumps in accordance with an audio input signal and thereby control the height of the stream of water without the use of valves. The light and sound aspects of the performance are delayed to compensate for mechanical delays in the system to ensure a synchronized performance. The fountain control system has the added ability of providing a unique performance based on different pieces of music without the need of reprogramming.
