Joseph Maurice Ravel was a French composer who is often associated with impressionism along with his elder contemporary Claude Debussy, although both composers rejected the term. In the 1920s and 1930s Ravel was internationally regarded as France's greatest living composer.
Born to a music-loving family, Ravel attended France's premier music college, the Paris Conservatoire; he was not well regarded by its conservative establishment, whose biased treatment of him caused a scandal. After leaving the Conservatoire Ravel found his own way as a composer, developing a style of great clarity, incorporating elements of baroque, neoclassicism and, in his later works, jazz. He liked to experiment with musical form, as in his best-known work, Boléro (1928), in which repetition takes the place of development. He made some orchestral arrangements of other composers' music, of which his 1922 version of Mussorgsky's Pictures at an Exhibition is the best known.
As a slow and painstaking worker, Ravel composed fewer pieces than many of his contemporaries. Among his works to enter the repertoire are pieces for piano, chamber music, two piano concertos, ballet music, two operas, and eight song cycles; he wrote no symphonies and only one religious work. Many of his works exist in two versions: a first, piano score and a later orchestration. Some of his piano music, such as Gaspard de la nuit (1908), is exceptionally difficult to play, and his complex orchestral works such as Daphnis et Chloé (1912) require skilful balance in performance.

Aram Khachaturian was a Soviet Armenian composer and conductor. He is considered one of the leading Soviet composers.
Born and raised in Tbilisi, the multicultural capital of Georgia, 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. 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 was the most renowned Armenian composer of the 20th century and the author of the first Armenian ballet music, symphony, concerto, and film score. While following the established musical traditions of Russia, he broadly used Armenian and to lesser extent, Caucasian, Eastern & Central European, and Middle Eastern peoples' folk music in his works. He is highly regarded in Armenia, where he is considered a "national treasure".
