Like a lot of Zachow's choral preludes. this one is also a fugue on the first phrase of the choral melody. In this case Zachow also employs a countersubject that he maintains throughout the piece. Zachow was a craftsman in counterpoint as he shows in this piece: the countersubject is written in double counterpoint, meaning it can be played both above and below the fugue subject without violating voice leading rules.
