While the score is always integral to its film, director Stanley Kubrick elevated music from soundtrack to character in his 1968 masterpiece, 2001: ASpaceOdyssey. Kubrick jettisoned much of the film's dialogue and instead used works from core classical repertoire to illustrate mood and character motivation as well as to highlight the film's motifs. Kubrick created a masterful marriage of the sound and the visual, but perhaps these three moments are the most striking and memorable: Richard Strauss' Also Sprach Zarathustra, which evokes the film's major theme of transition, from the startling opening scene to the ape's evolution, through man's ultimate transformation to star-child. Setting the choreography of the spaceship docking sequence to Johann Strauss' The Blue Danube waltz. Hal 9000's rendition of "DaisyBell", a heartbreaking scene which spurs the viewer to question what makes one human, what makes one machine? This version of the soundtrack also includes modernist composer Gyorgy Ligeti's Requiem, Lux Aeterna and Jupiter and Beyond, Adagio from Aram Khachaturian's Gayane Ballet Suite and the complete Hal9000 dialogue montage.
