Richard Strauss composed Also sprach Zarathustra in 1896 as a tone poem inspired by Friedrich Nietzsche, but it became globally famous when Stanley Kubrick used its opening fanfare in 2001: A Space Odyssey in 1968. In the film it accompanies the dawn and the emergence of early humans, linking the music to beginnings and evolution. Since then it has become shorthand for a momentous reveal in trailers, commercials, sports broadcasts and online edits, where even a few seconds instantly signal importance, scale and a touch of humour.
