The Canzona in C major, BuxWV166, begins with a four-voice fugue, its lively subject consisting entirely of semiquavers. The lengthy episode beginning at bar 24 is followed at bar 41 by a second, jig-like fugue; and the third and final fugue, like the first, is based on a subject consisting entirely of semiquavers.
