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.
