Aram Ilyich Khachaturian was a Soviet Armenian composer and conductor. He is considered one of the leading Soviet composers. Born and raised in Tbilisi, Khachaturian moved to Moscow in 1921 following the Sovietization of the Caucasus. Without prior music training, he enrolled in the Gnessin Musical Institute, subsequently studying at the Moscow Conservatory in the class of Nikolai Myaskovsky, among others. His first major work, the Piano Concerto (1936), popularized his name within and outside the Soviet Union. It was followed by the Violin Concerto (1940) and the Cello Concerto (1946). His other significant compositions include the Masquerade Suite (1941), the Anthem of the Armenian SSR (1944), three symphonies, and around 25 film scores. Khachaturian is best known for his ballet music—Gayane (1942) and Spartacus (1954). His most popular piece, the "Sabre Dance" from Gayane, has been used extensively in popular culture and has been performed by a number of musicians worldwide. His style is "characterized by colorful harmonies, captivating rhythms, virtuosity, improvisations, and sensuous melodies". During most of his career, Khachaturian was approved by the Soviet government and held several high posts in the Union of Soviet Composers from the late 1930s, although he joined the Communist Party only in 1943. Along with Sergei Prokofiev and Dmitri Shostakovich, he was officially denounced as a "formalist" and his music dubbed "anti-people" in 1948 but was restored later that year. After 1950 he taught at the Gnessin Institute and the Moscow Conservatory and turned to conducting. He traveled to Europe, Latin America and the United States with concerts of his own works. In 1957 Khachaturian became the Secretary of the Union of Soviet Composers, a position he held until his death. Khachaturian composed the first Armenian ballet music, symphony, concerto, and film score. He is considered the most renowned Armenian composer of the 20th century. While following the established musical traditions of Russia, he broadly incorporated Armenian and, to lesser extent, Caucasian, Eastern and Central European, and Middle Eastern peoples' folk music into his works. He is highly regarded in Armenia, where he is considered a "national treasure".
