[maxmsp] How to create visual representations of sound?

Hi,

I am new in the MAX/MSP environment, and would like to create visual representations of music, like an audio-socore, that could be followed based on paremeters like density of events, amplitude, fft etc..

I don`t know where to start, and don`t know to if I need jitter to do this.... Does anyone have some directions?

Thanks!
