Dmitri Dmitriyevich Shostakovich was a Soviet Russian composer and pianist and a prominent figure of 20th century music.
Shostakovich's works are broadly tonal and in the Romantic tradition, but with elements of atonality and chromaticism. In some of his later works (e.g., the Twelfth Quartet), he made use of tone rows. His output is dominated by his cycles of symphonies and string quartets, each numbering fifteen. The symphonies are distributed fairly evenly throughout his career, while the quartets are concentrated towards the latter part. Among the most popular are the Fifth and Seventh Symphonies and the Eighth and Fifteenth Quartets. Other works include the operas Lady Macbeth of Mtsensk, The Nose and the unfinished The Gamblers based on the comedy of Nikolai Gogol; six concertos (two each for piano, violin and cello); two piano trios; and a large quantity of film music.
