A film soundtrack is a collection of music and audio elements that accompany a movie. It includes songs, instrumental scores, and sound effects that enhance the storytelling and emotional impact of the film. Composers like John Williams and Hans Zimmer are known for creating memorable scores that help define a movie's atmosphere. Soundtracks can be original, composed specifically for the film, or they can feature existing songs that fit the movie's themes. They are often released as albums, allowing fans to enjoy the music outside of the film. Popular soundtracks, such as those from Disney movies, can achieve significant commercial success.
