Poétique musicale sous forme de six leçons

Igor Fyodorovich Stravinsky (17 June [O.S. 5 June] 1882 – 6 April 1971) was a Russian composer and conductor with French (from 1934) and American citizenship (from 1945). He is widely considered one of the most important and influential composers of the 20th century and a pivotal figure in modernist music. Born into a musical family in Saint Petersburg, Stravinsky grew up taking piano and music theory lessons. While studying law at the University of Saint Petersburg, he met Nikolai Rimsky-Korsakov and studied music under him until the latter's death in 1908. Soon after, Stravinsky met impresario Sergei Diaghilev, who commissioned him to write three ballets for the Ballets Russes's Paris seasons: The Firebird (1910), Petrushka (1911), and The Rite of Spring (1913), the last of which caused a near-riot at the premiere due to its avant-garde nature and later changed the way composers understood rhythmic structure.
