Also sprach Zarathustra, op. 30

Also sprach Zarathustra, Op. 30 (German: [ˈalzo ʃpʁaːx t͡saʁaˈtʊstʁa] , Thus Spoke Zarathustra or Thus Spake Zarathustra) is a tone poem by the German composer Richard Strauss, written in 1896 and inspired by Friedrich Nietzsche's 1883–1885 philosophical work of the same name. Strauss conducted its first performance on 27 November 1896 in Frankfurt. A typical performance lasts approximately 33 minutes. The initial fanfare – titled "Sonnenaufgang" ("Sunrise") in the composer's programme notes – became well and widely known after its repeated use as the main musical theme in Stanley Kubrick's 1968 film 2001: A Space Odyssey. Thereafter, Eumir Deodato's hit jazz-funk adaptation of the piece won the 1974 Grammy Award for Best Pop Instrumental Performance.
