When and Why Do Composers Use Enharmonic Modulation in Film Scores?
Enharmonic modulation is a harmonic technique that allows composers to pivot between keys by respelling a chord to transform its function. In film scores, this device is deployed at crucial narrative moments to create seamless key changes, evoke emotional transitions, and sustain tension through tonal ambiguity. Its use is driven by the need to align musical narrative with cinematic drama, often appearing at pivotal plot points or during character transformation.
