Alison, It's so nice to hear from you! Thanks for listening, and also thanks for the tip on that fugue. It never would have occurred to me to write a fugue on that subject. This fugue is kind of unusual inasmuch as each middle entry seems to be almost like a complete new exposition, except for the fact that the texture does not drop down to a single voice again. Certainly unusual to see all four voices do the subject in succession in the middle entries like this. Cool piece, though!
