Arduino: Sound Input to Light Output

Hello everyone!
I'm a Product design student at the Edinburgh College of Art (UK) and I have an show coming up soon!

I am wanting to create a string instrument ( Which is integrated ina wooden framed cube) in which I would like the Arduino chip pick up the vibrations by the use of a Guitar pickup.

I would the like the Arduino to translate the pitch and volume to different colours on RGB LED strips (12 Strips Total)
The pitch or key would be translated into different colours which are preassigned or it can be random.
The Volume would be translated into LED brightness.

So you play these strings and different colours will fade in or out on the RGB LED strips.

If anyone knows:
What RGB LED Strips to get
What coding to use for the Arduino
Anything else I need to get to make this Possible!

Thanks !!! Time is running out!!!
Victor
