What one-act ballet's music was written by an Austrian composer and conductor?
Anton Webern Anton Friedrich Wilhelm (von) Webern (] ; 3 December 188315 September 1945) was an Austrian composer and conductor. Along with his mentor Arnold Schoenberg and his colleague Alban Berg, Webern was at the core among those within and more peripheral to the circle of the Second Viennese School, including Ernst Krenek and Theodor W. Adorno. As an exponent of atonality and twelve-tone technique, Webern exerted influence on contemporaries Luigi Dallapiccola, Křenek, and even Schoenberg himself. As a tutor, Webern guided and variously influenced Arnold Elston, Frederick Dorian (Friederich Deutsch), Matty Niël, Fré Focke, Karl Amadeus Hartmann, Philipp Herschkowitz, René Leibowitz, Humphrey Searle, Leopold Spinner, and Stefan Wolpe.
Eugene Onegin (opera) Eugene Onegin (Russian: Евгений Онегин , "Yevgény Onégin"), Op. 24, is an opera ("lyrical scenes") in 3 acts (7 scenes), composed by Pyotr Ilyich Tchaikovsky. The libretto, organised by the composer himself, very closely follows certain passages in Alexander Pushkin's novel in verse, retaining much of his poetry. Tchaikovsky's friend Konstantin Shilovsky contributed M. Triquet's verses in Act 2, Scene 1, while Tchaikovsky himself arranged the text for Lensky's arioso in Act 1, Scene 1, and almost all of Prince Gremin's aria in Act 3, Scene 1.
