Linking Linking is a crucial agent in intermodal composition. Its function is analogous to superimposition in stereoscopic vision. It causes the sounds and images to interact and create the added dimension. In the process two elements are treated as equal and then unified. Apart from realistic examples from the external world and from the rare people with synesthetic capabilities, no sounds and images are associated together a priori.
Synesthesia has marginal importance as it differs from person to person.
Linking, therefore, may be described as a correspondence created between sounds and images that are not conventionally associated together. This unlikely collision of sounds and images causes both of them to be evaluated with equal attention. It combats the usual dominance of sight over hearing. The emancipation of hearing and consequently, the equality of media, together with the sense of referencing between them, are the two principal conditions for the perception of intermodal counterpoint fulfilled by linking. The basic rule for linking sounds and images is temporal coincidence.
