List of compositions by Dag Wirén

The career of the Swedish composer Dag Wirén (1905–1986) spanned six decades: his earliest pieces date to 1920, while his final project—the Flute Concertino—was completed in 1972. Today, Wirén is primarily remembered for his popular Serenade for Strings (1937), especially the Marcia (No. 4), which is often performed and recorded as a stand-alone concert piece. In addition to the Serenade, Wirén's most acclaimed works are: his four extant symphonies (Nos. 2–5), written from 1938 to 1964; the Sinfonietta (1934); his four extant string quartets (again, Nos. 2–5), written from 1935 to 1970; and his three concerti, respectively, for cello (1936), violin (1946), and piano (1950). Wirén was also a prolific composer for the stage and the silver screen: he wrote original scores to ten films, three ballets, two radio operettas, and numerous plays—although none of these is particularly well-known.
