The Austrian composer Arnold Schoenberg published four string quartets, distributed over his lifetime: String Quartet No. 1 in D minor, Opus 7 (1905), String Quartet No. 2 in F♯ minor, Op. 10 (1908), String Quartet No. 3, Op. 30 (1927), and the String Quartet No. 4, Op. 37 (1936).
In addition to these, he wrote several other works for string quartet which were not published. The most notable was his early String Quartet in D major (1897). There was also a Presto in C major (c. 1895),[1] a Scherzo in F major (1897),[2] and later a Four-part Mirror Canon in A major (c. 1933).[3] Finally, several string quartets exist in fragmentary form. These include String Quartet in F major (before 1897), String Quartet in D minor (1904), String Quartet in C major (after 1904), String Quartet Movement (1926), String Quartet (1926), String Quartet in C major (after 1927) and String Quartet No. 5 (1949).
Schoenberg also wrote a Concerto for String Quartet and Orchestra in B♭ major (1933): a recomposition of a work by the Baroque composer George Frideric Handel.
