A soundtrack is sound for a movie. 
Sometimes, music is made just for a film. This is called a score. A score uses instruments to tell a story.
Some people buy music from a movie. They can listen to it at home. This is called a soundtrack album.
Long ago, people made these on discs. They had to copy sounds many times.
Soundtracks make movies feel special. Do you have a favorite movie song?
A soundtrack is the sound for a movie, show, or game. 
Many people buy soundtrack albums to listen to at home. These albums often feature the music from the film. Some albums are called film scores. A score uses instruments to tell the story. A famous example is the music from Star Wars.
Other albums focus on songs. Some movies are musicals, like Grease. These albums feature the songs from the show. Some albums even have pop songs used in the background.
Video game soundtracks are also very popular. They include music from different levels and menus. In the past, making these was hard. Before tape, makers had to copy sounds from one disc to another. This could make the sound quality lower. Today, soundtracks help us feel the magic of a story.
A soundtrack is the audio that goes with a story. It can be for a movie, a radio show, or a video game. This sound matches the images you see on a screen. In a film, sounds often start on separate tracks. One track has the talking, one has sound effects, and one has music. Workers mix these together into one composite track. This is the final sound that the audience hears. 
Sometimes, people want to listen to this music at home. They buy a soundtrack album to hear their favorite parts again. These albums are often just the music from the film. They do not usually have the talking or the sound effects. Some albums are called film scores. A film score uses instruments to play themes. For example, the music in the Star Wars series is a famous film score. Other albums might have pop songs used in the background of a movie. 
Making these albums has changed a lot over time. In 1937, the Disney movie Snow White and the Seven Dwarfs had the first commercial soundtrack. It was released on 78 rpm discs in early 1938. Later, in 1946, the film Till the Clouds Roll By had the first live-action musical soundtrack. Back then, people did not have tape to record on. Producers had to copy sounds from one disc to another. They added transitions to make the music flow. This process could make the sound quality lower than the original. 
There are many different kinds of recordings you can find. Musical film soundtracks focus on songs, like in the movie Grease. Video game soundtracks are also very common now. They include music from levels, menus, and title screens. Some games, like Final Fantasy VII, have very popular music. Sometimes, an album might even include the dialogue from the film. A few rare albums, like the one for Romeo and Juliet, include many parts of the movie's talking. 
Soundtracks help tell a story through sound. They can make a romance feel sweet or a thriller feel scary. Some soundtracks even include new songs that were not in the movie. These are used to help promote the film to new fans. Many soundtracks can win big awards like Grammys. Composers like Henry Mancini became very famous for their work. His music for Peter Gunn won him two Grammys. Soundtracks connect the music we love to the stories we enjoy. 
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.
