One of the Five, the leading group of 19th century Russian nationalist composers, Rimsky-Korsakov embarked at first on a career as a naval officer, following the traditions of his family, later resigning from the service to devote himself entirely to music. He was proficient as an orchestrator and set himself to smoothing out some of the apparent crudities in the work of some of his fellow-composers, completing and revising works such as Borodin's opera Prince Igor and much of the seemingly uneven writing of Mussorgsky. He was respected as a teacher, his pupils including the young Stravinsky. Most generally known for his orchestral compositions, Rimsky-Korsakov wrote songs and choral music, chamber music and works for piano. His textbook on orchestration has been widely if not always wisely used.

Operas

Of the fifteen operas completed by Rimsky-Korsakov, mention may be made of The Snow Maiden, The Maid of Pskov, The Tale of Tsar Saltan, Mlada, Sadko, The Legend of the Invisible City of Kitezh and the satirical and once banned Le coq d'or (The Golden Cockerel). Orchestral and instrumental excerpts from some of these may be very familiar, including the famous Flight of the Bumble Bee, from The Tale of Tsar Saltan, a prince who turns himself into a bee and stings his wicked aunts.

Orchestral Music

Of the various orchestral works of Rimsky-Korsakov Capriccio espagnol (Spanish Caprice) and the Arabian Nights Sheherazade are by far the best known, followed by the Russian Easter Festival Overture. The title of the Capriccio espagnol is self-explanatory, while Sheherazade, with no detailed and specific programme, is based on the tales told by the princess Sheherazade, represented by a solo violin, in her effort to postpone the sentence of death declared on her by her master, the Caliph.
