4 Pieces for Violin and Piano, op. 115

The Four Pieces (in German: Vier Stücke), Op. 115, is a collection of four duos for violin and piano written in 1929 by the Finnish composer Jean Sibelius. They were published as a set in 1930 by the German firm Breitkopf & Härtel. Along with the standalone Novellette (Op. 102, 1922), the Danses champêtre (Op. 106, 1924–1925), and the Three Pieces (Op. 116, 1929), Sibelius's Op. 115 is among his late-career, mature works in the genre.
