Igor Fyodorovich Stravinsky (Russian: Игорь Фёдорович Стравинский) (17th June 1882 – 6th April 1971) was a Russian composer who first achieved international fame with three ballets commissioned by the impresario Serge Diaghilev and performed by Diaghilev's Ballets Russes (Russian Ballet): L'Oiseau de feu ("The Firebird") (1910), Petrushka (1911), and Le sacre du printemps ("The Rite of Spring") (1913). Stravinsky's compositional career was notable for its stylistic diversity. After his first, Russian (expressionistic), phase he turned in the 1920s to neoclassicism.
