The String Quintet in C major, Op. 29, written by Ludwig van Beethoven, was composed in 1801. This work is scored for string quartet and an extra viola. The Op. 29 is Beethoven's only full-scale, original composition in the string quintet genre; of his other quintet works, the Op. 4 is an extensively reworked arrangement of the earlier Octet for Winds, Op. 103, the String Quintet Op. 104 is an arrangement of an earlier piano trio, and the later fugue is a short work.
