Soundtrack

arts Maturity 7-9 Next article →

A soundtrack is a recorded audio signal that accompanies and synchronizes with images. This audio may belong to a book, drama, motion picture, radio program, television program, or video game. In the movie industry, the term refers to audio recordings used during film production or post-production. Colloquially, people use the word to describe a commercially released album containing music from a film or show. It can also describe the physical area on a film strip that holds the synchronized sound.

To create the sound you hear in a film, engineers use a process called mixing. Initially, the dialogue, sound effects, and music each exist on their own separate tracks. These individual layers are mixed together to create a single composite track. This composite track is the final version heard by the audience. Sometimes, a dubbing track is created later to translate a film into another language. This is often called an M&E track, which stands for music and effects. This track contains all sound elements except for the dialogue. A foreign distributor then adds the native language dialogue over the M&E track.

Soundtrack recordings exist in several distinct types. Musical film soundtracks focus primarily on songs, such as those found in the films *Grease* or *Evita*. Film scores are different because they showcase primarily instrumental musical themes and background music. Examples of famous scores include the *Star Wars* series and *Blade Runner*. Some movies contain both orchestral scores and pop songs, such as the *Shrek* series. Other albums simply collect popular songs heard in the background of non-musical movies, like *Top Gun*. Video game soundtracks are also unique. They often include music from levels, menus, title screens, and cut-scenes, as seen in *Final Fantasy VII*.

The history of the soundtrack began with early musical compositions for film. In 1908, Camille Saint-Saëns composed music specifically for the motion picture *L'assassinat du duc de Guise*. The first commercially issued film soundtrack was for the 1937 Walt Disney film *Snow White and the Seven Dwarfs*. RCA Victor Records released it in January 1938 on multiple 78 rpm discs. The first live-action musical to have a commercial soundtrack album was the 1946 film *Till the Clouds Roll By*. This album was issued as a set of four 10-inch 78 rpm records. Because tape did not exist yet, producers had to copy segments from playback discs. They copied and re-copied segments between discs to add transitions and cross-fades. This created many generations of copies, which caused the sound quality to suffer.

Terminology in this field can be quite complex and sometimes ambiguous. In the past, MGM Records used the term "original cast albums" to distinguish certain recordings. They wanted to separate music that would "lock to picture" from music that would not. An "Original Motion Picture Soundtrack" in its strictest sense contains music that stays in sync with the film. An "Original Cast Soundtrack" might refer to studio recordings by the original actors that were edited for time. Because producers are often ambiguous, the term "soundtrack" has grown to cover almost any recording from a film. This includes music re-recorded in a studio at a later date. Some rare albums even include the dialogue, such as the 2-LP set for *Who's Afraid of Virginia Woolf?*.

Soundtracks serve many important roles in the entertainment industry. They are often released on major record labels just like a musical artist's album. These albums can appear on music charts and win prestigious awards like Grammys. For example, composer Henry Mancini won an Emmy and two Grammys for his *Peter Gunn* soundtrack. Soundtracks also act as powerful promotional tools. Some soundtracks include new or exclusive pop music that was never actually heard in the film. These songs are included to help promote well-known artists and the film franchise. This can lead to songs peaking on the charts because of the movie's popularity.

Finally, soundtracks connect the auditory and visual worlds to create a complete experience. The style of the music often matches the genre of the media. A lighthearted romance might feature easy listening love songs. In contrast, a dark thriller might use hard rock or urban music. This connection helps set the mood and guides the audience's emotions. Whether through a massive orchestral score or a single pop song, the soundtrack is essential to storytelling. It transforms a silent sequence of images into a living, breathing world.
