How to make Musical Fountain? Answered

I am very much interested in making a musical fountain not a big fancy one but a small which can control itself on rhythm like lm3914 controls LED can it control water pumps as well? If not then which IC can control it and how? Please help.

Usually, I believe, these have a single pump driving a set of solenoid-controlled valves. You won't control these directly from an IC, since it probably can't handle the load; instead, you wire the IC to control a driver transistor which in turn controls the solenoid (or motor, or whatever).
