I spent Christmas Eve writing a silly fugue. Season’s greetings to you all!
(Subsequently edited to remove as many errors in the counterpoint as possible. The augmented/inverted canon at the end will never “really” work as it throws up too many second inversions and hidden fifths, etc., so I just left it as it is. Otherwise I think I removed most problems besides a couple of unresolved sevenths and incorrect leading tone movements. 侘寂.)
