Biquad – What Do The Five Coefficents Mean?

I am wondering how I can use the biquad coefficents to actually form usable filters/hybrid filters. I have looked at the helpfile, but don’t really have a good enough grasp on the maths to know how to manipulate the equation in musically significant ways. Could someone possibly link the coefficents to musically relevant terms, like Q, frequency, etc.?

I briefly looked at the coefficents filtergraph~ put out and saw that they all exist between -2 and 2, so I made this fun little patch which produces some serious random grunge:

ill take a more in depth look at filtergraph~ coefficents, but if anyone has already figured this out, it would be much appreciated if they could pass on their knowledge.
