Ah, I studied comp back at IU. Didn't explicitly study with Freund, but I attended some masterclasses with him. Great teacher... Are you there or did you just find this online?

And yes, there is a lot to know about fugue. This website provides some great info and visualizations of what's going on in Bach's fugues from the WTC...

I am performing this piece this weekend and I like to do a bit of an introduction for each piece. The part about Yesterday will be perfect for this audience.

From Indiana University class. With professor (composer) Don Freund.

Trying out my sight-reading ability on Bach prelude and fugue in C major, in a Dover collection of Baroque pieces, made me realize (on the fugue): 1) I have to climb up onto the keyboard to twist my fingers into the right position! and 2) I have no idea what is going on with the music! (you know-- all that reading and finger-twisting took all my attention) So thought I had better find out something about fugues-- what is stretto-- entries-- false entries-- etc. etc. (and no I am not undertaking the WTC any time soon but just curious in the meantime!!) Hope another benighted soul will find this enlightening as well. (Part 2 not included but available)

Good for you for seeking this out! There is a TON to learn about fugues and once you begin chipping away at the tip of the iceberg you'll realise what a genius Bach was. There are some other very good sights dealing with the WTC with analyses, scores, sound, etc. I'll take a look through my bookmarks and see what I can find. Twill post later.
