The band sound is the part full sound and editing result of different soundtracks, whether dialogues, sounds and music work or parallel accompaniment. Typically, and with rare exceptions, the term refers only to the music of a movie or the commercialization of the musical themes of a work such as video games, television and radio shows.
The inclusion of soundtracks in films was a task that took time. The first steps in accomplishing this was trying to get a projector and a phonograph to work together. When the cinema was silent, on many occasions there was musical accompaniment. At times, it was a great opportunity to see images and enjoy musical pieces by great artists. However, most of the time, the music did not match the action in the film and, in fact, the bands only simulated the noises of the reels of the tapes.
That is why it is also known as the "original soundtrack" because the music is composed exclusively for that performance, generally, in a commercial production, the director of the film meets the director of the orchestra (composer) in the post-production stage to compose together, the “soundtrack” is the moment when the director shows the images of the shoot to the musicians and the brands in which he wants a certain composition, which shows that the director has already incorporated what he wants transmit confirming that image and sound are the parts of the whole, then that "soundtrack" will be sold as a commercial product obviously separate from the image.
Since cinema was invented to this day, there are many movies that have seen their soundtrack become a critical part of their success. This has been the case with feature films such as " Rocky ", "The mission", "Grease", "The bridge over the River Kwai"., "What the wind took" or "Casablanca". "The Godfather", "Pulp Fiction"
Since the 1960s, soundtracks have acquired a more commercial character, especially for selling albums, taking into account the popularity of some artists such as The Beatles. Technology has allowed soundtracks to be an essential part of a movie, which allows to intensify the emotions that she wants to convey. In addition, it has achieved worldwide popularity of great artists such as Celine Dion with the soundtrack of the movie Titanic or Whitney Houston with the soundtrack of the movie The Bodyguard.
