Sound effects and music support the visual in terms of sound. Thus, it reaches and binds the viewer. The role of music is to arouse emotions. Music or sound effects, which contain noises, give the movie additional naturalness. Because certain activities produce very precise sounds that are long-standing, you expect to hear that sound when you see it.
Music can do even more
In the best case, you can achieve a holistic identification by sound. For example, when creating a series of explainer videos, you may choose a music theme that will be repeated in all the videos. In this way, the viewer does assign the video to a company based on its style. In addition, it establishes a link via the musical theme heard.
