Twelve Little Preludes

Twelve Little Preludes (French: Douze petits Préludes; German: Zwölf kleine Praeludien), BWV 924–930, 939–942 and 999, is a 19th-century compilation of short pieces, collected from various 18th-century manuscripts written by Johann Sebastian Bach and others. Notwithstanding their diverse origin and characteristics, they were published as a set of twelve keyboard preludes by Bach in, amongst others, the 36th volume of the Bach-Gesellschaft Ausgabe (BGA).

Several collections of short keyboard preludes by Bach were published for didactic purposes from the 19th century. In the 20th century Ferruccio Busoni combined the Twelve Little Preludes with the Six Little Preludes, BWV 933–938 into a set of 18 little preludes.
