Sketch sheet 1770ε (3) = Sk 1770b: Exposition of a fugue in C for SATB (= K.3 417a Appendix, B K.6: 417B3)

Counterpoint plays a rather subordinate role in music of the Classical era. However, Mozart composed—in addition to the canons (see work group 10)—some individual contrapuntal pieces throughout his life. A considerable number of these remained unfinished and were never intended for performance but were presumably written for study and teaching purposes (see Anhang H).
