Dictionary of Marketing Terms: background music
background music
in motion picture or broadcast production, live or recorded music played behind the spoken dialogue or announcements to establish mood or to influence the emotional impact of a scene.
In advertising, background music will sometimes work to affect the disposition of the potential consumer of a product or service. Studies indicate that background music will favorably influence consumers when the appeal is emotional and/or simple. However, when the appeal is complicated and/or practical, background music does not work in favor of the product being advertised and is seldom used.
