Anton Bruckner's String Quartet in C minor WAB 111, was written in 1862 as a student exercise for Otto Kitzler, a preliminary to exercises in orchestration. The manuscript of the quartet, which was composed between 28 July and 7 August 1862, was found on pp. 165–196 of the Kitzler-Studienbuch. In the spring of 1862, Bruckner had already composed a Scherzo for string quartet in G minor. This earlier exercise was found on pp. 70–74 of the Kitzler-Studienbuch.
