Influence of Music Psychology on the Consistency of Mood in Movies: A Review of Historical Works and Empirical Research

Abstract

This study takes music and its corresponding psychological effects in the historical movie works as the research object, sorts out the internal connection between the musical form factors of the movie and the audience's psychology, and then analyzes the tense psychological emotions and their musical psychological aspects through movie examples, explores the sound factors and their psychological contrast effects, and finally reveals the impact of changes in proper melody on psychological outcomes. Research has found that the loudness of sound is closely related to emotional fluctuations, as well as the psychological responses brought by different types of music in dynamic and static movie scenes. When creating the sound of movie and television works, unique loudness designs for language and sound effects often bring unexpected results. The sounds in movies are all compound sounds, different from the direct physiological stimulation of pure tones on the auditory system. The tone cognition of compound sounds not only includes physiological reactions but also brings specific psychological effects. The psychological perception brought about by changes in sound frequency is different from the psychological impacts of loudness, and the psychological outcomes related to frequency are mainly attached to music and musicalized sound in creation. The rhythm, frequency, and emphasis of sound can more effectively and accurately guide the audience to realize the spatiotemporal transformation in the movie, providing them with a better viewing experience. The connection between "real" and "nonreal" scenes in historical movies usually involves high-frequency instruments and significant changes in the rhythm of the music. These self-explanatory psychological suggestive methods, combined with symbolic music, can create a specific "hypnotic" effect on the whole, bringing a combination of natural and virtual psychological effects to the audience.
