Document 3: UK Classical Charts: The UK Classical Charts are three record charts based on classical music in the United Kingdom: the Classical Artist Albums Chart, the Classical Compilation Albums Chart and the Specialist Classical Albums Chart. The charts are commercial monitoring and marketing devices used by the UK music industry to measure its effectiveness in promoting and selling albums, nominally in the field of classical music. All three charts are compiled by the Official Charts Company (OCC). The measurements are made by collating the returns of sales from a number of well-known music stores (high street and online stores) on a regular basis, and this enables a ranking to be established. Most classical artist album sales in the UK are from crossover artists. For an album to be classified as classical in the charts, it has to have 60% of the playing time dedicated to "classical or traditional music". Only albums that entirely classical or traditional music qualify for inclusion in the Specialist Classical Albums Chart.

Document 5: A Clockwork Orange (soundtrack): The soundtrack to Stanley Kubrick's A Clockwork Orange was released to accompany the 1971 film of the same name. The music is a thematic extension of Alex's (and the viewer's) psychological conditioning. The soundtrack of "A Clockwork Orange" comprises classical music and electronic synthetic music composed by Wendy Carlos (then Walter Carlos). Some of the music is heard only as excerpts, e.g. Edward Elgar's "Pomp and Circumstance March No. 1" (a.k.a. "Land of Hope and Glory") ironically heralding a politician's appearance at the prison. The main theme is an electronic transcription of Henry Purcell's "Music for the Funeral of Queen Mary", composed in 1695, for the procession of Queen Mary's cortège through London en route to Westminster Abbey. "March from 'A Clockwork Orange'" (based on the choral movement of the Ninth Symphony by Beethoven) was the first recorded song featuring a vocoder for the singing; synthpop bands often cite it as their inspiration. Neither the end credits nor the soundtrack album identify the orchestra playing the Ninth Symphony excerpts, however, in Alex's bedroom, there is a close-up of a microcassette tape labeled: "Deutsche Grammophon – Ludwig van Beethoven – Symphonie Nr. 9 d-moll, op. 125 – Berliner Philharmoniker – Chor der St. Hedwigskathedrale – Ferenc Fricsay – Irmgard Seefried, Maureen Forrester, Dietrich Fischer-Dieskau, Ernst Haefliger".
