On April 14th he was dead. His principal orchestral works are: "Le Poeme divine," Opus 43; "Le Poeme de l'Extase," Opus 54; and "Prometheus," Opus 60. It is not easy to say which of his many compositions for the pianoforte are the most important. Sonata No. 7, Opus 64; Sonata No. 8, Opus 66; Sonata No. 9, Opus 68; and Sonata No. 10, Opus 70; are perhaps the most magistral. STRAWINSKY Igor Fedorovitch Strawinsky was born at Oranienbaum near Petrograd, June 5th, 1882. His father was a bass singer attached to the court. Igor was destined for a legal career. But in 1902 he met Rimsky-Korsakoff in Heidelberg, and abandoned all idea of studying the law. He studied with Rimsky till 1906. His "Scherzo fantastique," inspired by Maeterlinck's _Life of the Bee_, which was produced in 1908, attracted the attention of Sergei Diaghilew to the young composer, and secured him a commission to write a ballet for Diaghilew's organization. The immediate result was "L'Oiseau de feu," which was composed and produced in 1910. "Petruschka" was written in 1911, the composer residing in Rome at the time. "Le Sacre du printemps" was written in Clarens, where Strawinsky generally lives. It was produced in Paris in 1913. The opera "Le Rossignol," of which one act was completed in 1909, and two in 1914, was produced in Paris and in London just before the war. A new ballet "Les Noces villageoises" has not as yet been produced. Other of Strawinsky's compositions are: Opus 1, "Symphony in E-flat"; Opus 2, "Le Faune et la Bergere," songs with orchestral accompaniment; Opus 3, "Scherzo fantastique"; Opus 4, "Feuerswerk"; Opus 5, "Chant funebre" in memory of Rimsky-Korsakoff; Opus 6, Four Studies for the pianoforte; Opus 7, Two songs; "Les Rois des Etoiles," for chorus and orchestra; Three songs on Japanese poems with orchestral accompaniment; Three pieces for string-quartet; An unpublished pianoforte sonata; A ballet for clowns.
