Info needed bout Musical Fountain...

Hey guys can u help me out in designing a musical fountain that is to regulate the flow of the water into the fountain according to the music played....

Those valves are probobly only fast enugh for opening on the bass beat

An low pass filter op amp and transistor will work

I have to say that I've seen it done but the water flow rates, as expected, do not change quite so quickly as lights do. Water flowrate change in a more general sense rather than at each note. It probably requires some careful selection of music as well. It is a nice effect.

Couldn't one make the water plat to the music that is to be played after a second or two so that everything looks in synchrno?
