"Once Upon a Time in the Wes
t" is a soundtrack composed by Ennio Morricone, from the 1968 western film of the same name directed by Sergio Leone, released in 1972. The film score sold about 10 million copies worldwide. The soundtrack features leitmotifs
that relate to each of the main characters of the movie (each with their own theme music), as well as to the spirit of the American West. The theme music for the Claudia Cardinale character has wordless vocals by Italian singer Edda Dell'Orso
. 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.
