A movie or film score is the background music of a film (which is generally categorically separated from songs used within a film). The term soundtrack may be confused with film score. A soundtrack, however, contains everything audible in the film including sound effects and dialogue. Soundtrack albums may also include songs featured in the film as well as previously released music by other artists. A score is written specifically to accompany a film, by the original film's composer(s).
Each individual piece of music, within a film's score, is called a cue and is typically a composition for instruments (e.g. orchestra) and/or non-individually featured voices. Since the 1950s, a growing number of scores are electronic or a hybrid of orchestral and electronic instruments. Since the invention of digital technology and audio sampling, many low budget films have been able to rely on digital samples to imitate the sound of real live instruments.
Tag film score is most appropriated for used in the context as described above. .
