A film score (also sometimes called background score, background music, film music or incidental music) is original music written specifically to accompany a film. The score forms part of the film's soundtrack, which also usually includes dialogue and sound effects, and comprises a number of orchestral, instrumental, or choral pieces called cues, which are timed to begin and end at specific points during the film in order to enhance the dramatic narrative and the emotional impact of the scene in question. Scores are written by one or more composers, under the guidance of, or in collaboration with, the film's director or producer and are then usually performed by an ensemble of musicians – most often comprising an orchestra or band, instrumental soloists, and choir or vocalists – and recorded by a sound engineer.
Film scores encompass an enormous variety of styles of music, depending on the nature of the films they accompany. The majority of scores are orchestral works rooted in Western classical music, but many scores are also influenced by jazz, rock, pop, blues, new-age and ambient music, and a wide range of ethnic and world music styles. Since the 1950s, a growing number of scores have also included electronic elements as part of the score, and many scores written today feature a hybrid of orchestral and electronic instruments.
Pi, also titled π, is a 1998 American surrealist psychological thriller film written and directed by Darren Aronofsky in his directorial debut. The film earned Aronofsky the Directing Award at the 1998 Sundance Film Festival, the Independent Spirit Award for Best First Screenplay and the Gotham Open Palm Award. The title refers to the mathematical constant pi. The film is notable for its covering of an array of themes including religion, mysticism and the relationship of the universe to mathematics. The story about a mathematician and the obsession with mathematical regularity contrasts two seemingly irreconcilable entities: the imperfect, irrational humanity and the rigor and regularity of mathematics, specifically number theory.
Max Cohen is the story's protagonist and unreliable narrator. Unemployed, and living in a dreary Chinatown apartment in New York City, Max is a number theorist who believes that everything in nature can be understood through numbers. He is capable of doing simple arithmetic calculations involving large numbers in his head, a skill that impresses Jenna, a small Chinese-American girl with a calculator who lives in his apartment building. Max also suffers from cluster headaches, as well as extreme paranoia, hallucinations, and social anxiety disorder. Other than Devi, a young woman living next door who sometimes speaks to him, Max's only social interaction is with Sol Robeson, his old mathematics mentor who is now an invalid.
