Kubrick is credited with introducing Hungarian composer György Ligeti to a broad Western audience by including his music in "2001", "The Shining" and "Eyes Wide Shut". According to Baxter, the music in "2001" was "at the forefront of Kubrick's mind" when he conceived the film. During earlier screening he played music by Mendelssohn and Vaughan Williams, and Kubrick and writer Clarke had listened to Carl Orff's transcription of "Carmina Burana", consisting of 13th century sacred and secular songs. Ligeti's music employed the new style of micropolyphony, which used sustained dissonant chords that shift slowly over time, a style he originated. Its inclusion in the film became a "boon for the relatively unknown composer" partly because it was introduced alongside background by Johann Strauss and Richard Strauss.
