A film score is original music written specifically to accompany a film. The score 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 most often performed by an ensemble of musicians – usually including an orchestra or band, instrumental soloists, and choir or vocalists – known as playback singers – and recorded by a sound engineer. The term is less frequently applied to music written for media such as live theatre, television and radio programs, and video games, and said music is typically referred to as either the soundtrack or incidental music.
