The soundtrack of "Moonraker" was composed by John Barry and recorded in Paris, again, as with production, marking a turning point away from the prior studio, CTS Studios in London. The score also marked a turning point in John Barry's output, abandoning the Kentonesque brass of his earlier Bond scores in favor of slow, rich string passages – a trend which Barry would continue in the 1980s with scores such as "Out of Africa" and "Somewhere in Time". For "Moonraker", for the first time since "Diamonds Are Forever" (1971), Barry used a piece of music called "007" (on track 7), and "Bond smells a rat", the secondary Bond theme composed by Barry and introduced in "From Russia with Love" during Bond's escape with the Lektor; some classical music pieces were also included in the film. For the scene where Bond visits Drax in his chateau, Drax plays Frédéric Chopin's Prelude no. 15 in D-flat major (op. 28), "Raindrop", on his grand piano (although he plays in the key of D major). Tritsch-Tratsch-Polka by Johann Strauss II was used during the hovercraft scene on the Piazza San Marco in Venice, and Tchaikovsky's "Romeo and Juliet Overture" plays when Jaws meets Dolly following his accident. Other passages pay homage to earlier films, including Richard Strauss's "Also sprach Zarathustra" (op. 30), associated with "2001: A Space Odyssey", with the hunting horn playing its distinctive first three notes, Elmer Bernstein's theme from "The Magnificent Seven" when Bond appears on horseback in gaucho clothing at MI6 headquarters in Brazil, and the alien-contacting theme from "Close Encounters of the Third Kind" as the key-code for a security door as mentioned previously. The Italian aria "Vesti la giubba" from Ruggero Leoncavallo's opera "I Pagliacci", was sung in Venice before one of the henchmen falls to his death from a building, landing inside a piano.
