Dmitri Shostakovich's String Quartet No. 5 in B flat major (Op. 92) was composed in autumn 1952. It was premiered in Leningrad in November 1953 by the Beethoven Quartet, to whom it is dedicated. It consists of three movements, performed without a break:
Playing time is approximately 30 minutes.
The work grows from a five note motif: C, D, E flat, B and C sharp, which contains the composer's musical monogram - DSCH - (E flat being S and B being H in German). This monogram appears in a number of his other string quartets, including the Eighth, as well as his Tenth Symphony.
