Nielsen wrote four string quartets. The First String Quartet No. 1 in G minor, Op. 13 (1889, revised 1900) contains a "Résumé" section in the finale, bringing together themes from the first, third and fourth movements. The Second String Quartet No. 2 in F minor, Op. 5 appeared in 1890 and the Third String Quartet in E-flat major, Op. 14 in 1898. The music historian Jan Smaczny suggests that in this work "the handling of texture is confident and far less derivative than in earlier works ... quartet prompts the most regret that Nielsen did not pursue the genre further ... to parallel his later symphonic development". The Fourth String Quartet in F major (1904) initially received a mixed reception, with critics uncertain about its reserved style. Nielsen revised it several times, the final version in 1919 being listed as his Op. 44.
