The introduction delineates a number of models of audiovisual relations, which have marked different practices but retain a sense of common ‘core’. These include silent cinema, Classical film score, film musicals, television drama music, music video and video games music. Each of these models embodies a conceptualization of the relationship between sound and image, and one ultimately derived more from visual form rather than musical form and logic. It is arguable that these models are a direct result of technological developments and industrial efficiency models, yet each approach remains as a particular strategy for audiovisual culture, despite significant differences of approach between respective media.
