  :Hey thanks for your reply. I agree about the entry/episode structure some kind of chart may be a good idea; I think it would also be nice to have a short section, perhaps linking to separate article on the sort of material used in the episodes with some examples.   :- As far as I can tell there are several definitions of counter-exposition, I have seen it used interchangeably with 'middle-entry', and I think as you described it can also denote any 're-exposition' with the keys/opening scale degrees switched around, or for example ,I've seen it used to describe 're-expositions' with the subjects and countersubjects in inversion (like in the G major fugue WTC book I). I guess the best thing to do since Grove is pretty unclear on the subject, just mention the various uses of the term, and keep basic middle-entries separate. The examples you have look great, the Pachelbel sounds like a good idea to me + I have most of the Bach WTC fugues in lilypond format, which can easily be manipulated into diagrams (like the one for false entry I created).  :Free counterpoint isn't a fugue specific term, you're right of course ! - But it is the correct term to describe material that accompanies the subject at one point but then does not reoccur in this role again - like in the f sharp minor fugue, WTC book II beneath the answer in the exposition, - I have a couple of references for this that I can use.  :Anyway thanks very much for your advice, there is lots left to be done but hopefully (when I get enough time) it'll end up looking ok.
