Once Upon a Time in the West (Italian: C’era una volta il West) is a 1968 epic Spaghetti Western film directed by Sergio Leone.
The music was written by composer Ennio Morricone, Leone’s regular collaborator, who wrote the score under Leone’s direction before filming began. As in The Good, the Bad and the Ugly, the haunting music contributes to the film’s grandeur and, like the music for The Good, the Bad and the Ugly, is considered one of Morricone’s greatest compositions.
The film features leitmotifs that relate to each of the main characters (each with their own theme music) as well as to the spirit of the American West. Especially compelling are the wordless vocals by Italian singer Edda Dell’Orso during the theme music for the Claudia Cardinale character. It was Leone’s desire to have the music available and played during filming. Leone had Morricone compose the score before shooting started and would play the music in the background for the actors on set.
