'''Nikolai Andreyevich Rimsky-Korsakov''' (; Russia was using old style dates in the 19th century, and information sources used in the article sometimes report dates as old style rather than new style. Dates in the article are taken verbatim from the source and are in the same style as the source from which they come.) was a Russian composer, and a member of the group of composers known as The Five.The Five, also known as The Mighty Handful or The Mighty Coterie, refers to a circle of composers who met in Saint Petersburg, Russia, in the years 1856-1870: Mily Balakirev (the leader), César Cui, Modest Mussorgsky, Nikolai Rimsky-Korsakov, and Alexander Borodin. He was a master of orchestration. His best-known orchestral compositions--''Capriccio Espagnol'', the ''Russian Easter Festival Overture'', and the symphonic suite ''Scheherazade''--are 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 classical music. This style employed Russian folk song and lore along with exotic harmonic, melodic and rhythmic 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. His techniques of composition and orchestration were further enriched by his exposure to the works of Richard Wagner.
For much of his life, Rimsky-Korsakov combined his composition and teaching with a career in the Russian military--at first as an officer in the Imperial Russian Navy, then as the civilian Inspector of Naval Bands. He wrote that he developed a passion for the ocean in childhood from reading books and hearing of his older brother's exploits in the navy. This love of the sea might have influenced him to write two of his best-known orchestral works, the musical tableau ''Sadko'' (not to be confused with his later opera of the same name) and ''Scheherazade''. Through his service as Inspector of Naval Bands, Rimsky-Korsakov expanded his knowledge of woodwind and brass playing, which enhanced his abilities in orchestration. He passed this knowledge to his students, and also posthumously through a textbook on orchestration that was completed by his son-in-law, Maximilian Steinberg.
Rimsky-Korsakov left a considerable body of original Russian nationalist compositions. He prepared works by The Five for performance, which brought them into the active classical repertoire (although there is controversy over his editing of the works of Modest Mussorgsky), and shaped a generation of younger composers and musicians during his decades as an educator. Rimsky-Korsakov is therefore considered "the main architect" of what the classical music public considers the Russian style of composition. His influence on younger composers was especially important, as he served as a transitional figure between the autodidactism which exemplified Glinka and The Five and professionally trained composers which would become the norm in Russia by the closing years of the 19th century. While Rimsky-Korsakov's style was based on those of Glinka, Balakirev, Hector Berlioz, and Franz Liszt, he "transmitted this style directly to two generations of Russian composers" and influenced non-Russian composers including Maurice Ravel, Claude Debussy, Paul Dukas and Ottorino Respighi.Abraham, ''New Grove (1980)'', 16:34.
