Also sprach Zarathustra, Op. 30 is a tone poem by German composer Richard Strauss, composed 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 roughly 33 minutes.
The initial fanfare - titled "Sunrise" in the composer's programme notes - became well known after its use in Stanley Kubrick's 1968 film 2001: A Space Odyssey.
Eumir Deodato's jazz-funk hit version won the 1974 Grammy Award for Best Pop Instrumental Performance.
