Music fountain control states of water and lamps with musical characteristic. A good musical fountain is a wonderful artwork, which may make our environment more beautiful and joyful. And its control system is the key technique. 

With the developing of life, the more beautiful environment is needed. The petty music fountain becomes an important branch, which is applied to these situations. While a disadvantage of the petty music fountain is incompatible.  The research of the control system about the petty music fountain will show high economic and social benefits.        

Musical fountain is a type of animated fountain for entertainment purposes that creates an aesthetic design and sometimes a three-dimensional image. This is done by using the effects of sound waves and light or laser against water particles, in which the water streams, activated in strategically-timed durations, refract and reflect the light, and in doing so,  a three-dimensional image is created. Many of the more well-known ones are large scale, and use hundreds of water jets and laser emitters, the cost of which runs up into the millions of dollars, although smaller household forms exist where the budget ranges to around a thousand dollars. Compurterised fountains, also generally called musical fountains, appear to respond to music but have been programmed beforehand. The earliest of these were played manually by a live operator, who usually controlled pumps or valves and sometimes lights by way of switches on a control panel. Music was almost always live. Later, choreography could be prerecorded on a punched paper card which was scanned by a computer; and even later, it could be recorded on magnetic tape or, in the most modern shows, on a CD along with the music. Even so, the choreography must still be painstakingly programmed by hand, some types of shows being played live from a control console and connected to a computer  that records the operator's actions for later automatic playback. Himalay offers software and hardware that cause pumps to turn  on and off and lights to change in response to the bass and treble of music fed through the system, causing the  fountain to respond  automatically without a need for manual choreography.
