3 (soundtrack)

A soundtrack is a collection of audio recordings created for, or as a companion to, a visual medium. While most commonly associated with motion pictures (films), soundtracks can also accompany television shows, video games, and even stage productions. The term originally referred to the strip of celluloid film along the side of a movie that contained the recorded audio.

A soundtrack album is a commercially released collection of musical pieces featured in the associated visual work. This album may include:

• Original Score: Music specifically composed for the visual work, often instrumental. This is sometimes referred to as the "film score" or "background music."

• Songs: Pre-existing popular songs licensed for use in the visual work. These songs often contribute to the atmosphere or character development.

• Dialogue excerpts: Selected lines of dialogue from the visual work, though less common in modern soundtrack albums.

• Sound effects: Environmental sounds or specific effects used in the visual work, also less common in modern soundtrack albums.

The purpose of a soundtrack is multifaceted. It enhances the emotional impact of the visual narrative, helps to establish the setting and mood, underscores themes, and can serve as a marketing tool, promoting both the visual work and the artists featured on the album. The popularity of a soundtrack can often contribute to the success of the associated film or television show and vice-versa.
