Music is often combined with dialogue and natural sound effects. During the silent film era, music was sometimes the only sound, permeating the entire film from beginning to end. Due to the advancement of recording technology, in the sound film period, in addition to music, it was also possible to record language and natural sound effects, which relieved the music overload phenomenon in the silent film period.

Directors and composers start from the real needs of the film and use music appropriately and effectively only when expressing lyricism and dramatic atmosphere. In this way, it not only conforms to the artistic laws of music, but also improves the aesthetic function of comprehensive film art. This allows music to truly develop into an important and organic part of the comprehensive art of film, and it also promotes the formation of a segmented statement structure for film music.
