Nikolai Rimsky-Korsakov was a Russian composer, and a member of the group of composers known as The Five. He was a master of orchestration. His best-known orchestral compositions—Capriccio Espagnol, the Russian Easter Festival Overture, and the symphonic suite Scheherazade—are considered staples of the classical music repertoire, along with suites and excerpts from some of his 15 operas. Scheherazade is an example of his frequent use of fairy tale and folk subjects. Rimsky-Korsakov believed, as did fellow composer Mily Balakirev and critic Vladimir Stasov, in developing a nationalistic style of music, including Russian folk song and lore along with exotic elements in a practice known as musical orientalism, and eschewed traditional Western compositional methods. However, Rimsky-Korsakov appreciated Western musical techniques after he became a professor of musical composition, harmony and orchestration at the Saint Petersburg Conservatory in 1871. He undertook a rigorous three-year program of self-education and became a master of Western methods, incorporating them alongside the influences of Mikhail Glinka and fellow members of The Five.
