chord progressions

Man, this is just too big a question.

Olav Torvund has a superb, but messily laid out site on Chord Progressions.  It'll take you weeks to work through, but contains a lot of meat.

I would suggest you first go through David Hodge's articles on this site.  The best one to start with is probably A Before E (Except After C).

Then perhaps the rest of the articles in the Songwriting section.

Dude, it's all about this article:

It sites a lot of other...sites... in fact,  its how I found this place!  Enjoy!
