Music of the Soviet Union varied in many genres and epochs. The majority of it was considered to be part of the Russian culture, but other national cultures from the Republics of the Soviet Union made significant contributions as well. The Soviet state supported musical institutions, but also carried out content censorship.
According to Lenin:
Every artist, everyone who considers himself an artist, has the right to create freely according to his ideal, independently of everything. However, we are Communists and we must not stand with folded hands and let chaos develop as it pleases. We must systemically guide this process and form its result.
Classical music of the Soviet Union developed from the music of the Russian Empire. It gradually evolved from the experiments of the revolutionary era, such as orchestras with no conductors, towards classicism favored under Joseph Stalin's office.
The music patriarchs of the era were Prokofiev, Shostakovich and Aram Khachaturian. With time, a wave of younger Soviet composers, including Georgy Sviridov, Tikhon Khrennikov, Alfred Schnittke managed to break through.
Many musicians from the Soviet era have established themselves as world's leading artists: violinists David Oistrakh, Leonid Kogan, Gidon Kremer, Viktor Tretyakov and Oleg Kagan; cellists Mstislav Rostropovich, Daniil Shafran, and Natalia Gutman; violist Yuri Bashmet; pianists Sviatoslav Richter, Emil Gilels and many other musicians.
