Classical music (music created by musicians who are commonly not classically trained, often from a purely oral tradition). Some composers, like Dvořák and Smetana, have used folk themes to impart a nationalist flavor to their work, while others like Bartók have used specific themes lifted whole from their folk-music origins. Certain staples of classical music are often used commercially (either in advertising or in movie soundtracks). In television commercials, several passages have become clichéd, particularly the opening of Richard Strauss' "Also sprach Zarathustra" (made famous in the film "") and the opening section "O Fortuna" of Carl Orff's "Carmina Burana"; other examples
2001: A Space Odyssey (soundtrack) the music from Ligeti's "Atmosphères" which is heard when Bowman actually enters the Star Gate. No music is heard during the monolith's much briefer final appearance in Dave Bowman's celestial bedroom which immediately precedes the "Zarathustra"-accompanied transformation of Bowman into the Star-Child. A shorter excerpt from "Atmosphères" is heard during the pre-credits prelude and film intermission, which are not in all copies of the film. The adagio movement "Carpet Weavers" from Aram Khatchaturian's "Gayane" ballet suite no. 3. is heard during the sections that introduce Bowman and Poole aboard the "Discovery" conveying a somewhat lonely and mournful quality.
