With its schema-activating potential to influence an audience’s perception and interpretation of film plot and protagonists, film music goes far beyond the role of an emotionalizing accessory in film contexts. For this review, 24 German and English empirical studies that tested music’s potential to convey meaning were identified to be compared in their research questions, the characteristics of their methods, designs, samples, and stimulus materials, as well as main results. Depending on the degree of realism and the abstraction level of the audio-visual stimulus material, differently connoted music or music of different genres trigger supra-individual associations, which make the recipients’ perceptual patterns and evaluations of film plot and protagonists predictable. The review provides a systematization of music’s effects as well as methodological and content-related indications for future research.
