Carnaval, Op. 9, is a work by Robert Schumann for piano solo, written in 1834–1835 and subtitled Scènes mignonnes sur quatre notes. It consists of 21 short pieces representing masked revelers at Carnival, a festival before Lent. Schumann gives musical expression to himself, his friends and colleagues, and characters from improvised Italian comedy. He dedicated the work to the violinist Karol Lipiński.

Davidsbündlertänze, Op. 6, is a group of eighteen pieces for piano composed in 1837 by Robert Schumann, who named them after his music society Davidsbündler. The low opus number is misleading: the work was written after Carnaval, Op. 9, and the Symphonic Studies, Op. 13.
