The String Quintet in C major, Op. 29, written by Ludwig van Beethoven, was composed in 1801.[1] This work is scored for string quartet and an extra viola (two violins, two violas, and cello). 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.
The composer dedicated this work to Count Moritz von Fries, a patron to whom Beethoven also dedicated two other works of the same year—the Violin Sonatas No. 4 and No. 5—as well as his later Seventh Symphony.
