Hey thanks for your reply I agree about the entryepisode 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 counterexposition I have seen it used interchangeably with middleentry and I think as you described it can also denote any reexposition with the keysopening scale degrees switched around or for example Ive seen it used to describe reexpositions 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 middleentries 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 isnt a fugue specific term youre 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 itll end up looking ok
