String Quartet No. 5 (Shostakovich)

The work grows from a five-note motif, C–D–E–B–C, which contains the four pitch-classes of the composer's musical monogram: DSCH (E being "Es" and B being "H" in German). This motif appears in a number of his other string quartets, including String Quartet No. 8, as well as his Symphony No. 10.
