Look in Google at the hundreds of "Color Organ Circuits".

Thanks Audioguru, but i can only find either 2 or 3 channel or 120v,

I do not recall any 2 ch. colour organs. The reason for 3 channels is that there are only 3 primary colours. Mixing these will give you the full visual spectrum (excepting grays, but then gray is not a colour).
Also: if you have difficulty with the 120/240 volt thing: do not go there, it can be leathal!

A color Organ shows bass, mid-frequencies and high frequencies in 3 channels. You want an audio spectrum analyser but most have 7 to 23 bands.

ok, i think i may have confused you, i want something that changes with the beat. i have 4 lights par38 80w. green, blue, red, orange. i want it to change to each individual color each time deep beat is sounded. like a beat of a song. i dont want it to show frequency for each light color but change each beat.
thanks so far.

Then you want a simple sequencer made from a CD4017 IC. An opamp can be a preamp with a lowpass filter so that the bass is passed and the other frequencies are reduced.
Since you are using ordinary filament light bulbs that turn on slowly then you should use a peak-detector circuit to extend the time of each beat so there is enough time for the light bulb to turn on completely.
An opto-isolator or transformer must be used at the audio input to isolate it from the mains. Then triacs can be used to turn on the light bulbs. The CD4017 IC drives the triacs.
