Symphony No. 7, known as the 'Leningrad' Symphony, is a major orchestral work composed by Dmitri Shostakovich during World War II. Written in 1941, it became a powerful symbol of Soviet resistance against the Nazi invasion, particularly during the Siege of Leningrad, which lasted from 1941 to 1944. The symphony not only reflects the emotional turmoil of war but also embodies the spirit of endurance and resilience among the Soviet people.
