Need Help With Bluetooth, Processing and LEDs to Music

Hi, i'm trying to complete this;

with an HC-06 bluetooth module instead of a usb modem. I only know basic C so I can't quite figure this out by myself. My goal is to basically use this bluetooth module to receive signals from the computer (mac) and to light up the LEDs to music. Any suggestions are helpful.
Thanks.

So you basically want to communicate your laptop and the arduino remotely via bluetooth?

Check out if there is an existing bluetooth serial communication library available for processing.
