Final answer:
The kind of cadence the music ends with in a film reflects the emotional context of the scene, potentially being dissonant for tension or consonant for resolution.
Step-by-step explanation:
The kind of cadence a piece of music ends with largely depends on the emotional context established by the composition. In the scenario described with the heroine sitting on a park bench accompanied by dissonant chords, a sense of danger is evoked.
This suggests the piece could conclude on a dissonant or unfinished cadence, leaving the listener with a feeling of tension or unease.
In contrast, if the music was soft and soothing leading to a happy moment, it might end with a consonant or resolved cadence, giving a sense of closure and satisfaction.
This difference in ending cadences showcases the powerful role music plays in storytelling and the manipulation of the viewer's emotions, reflecting the underlying narrative of the scene.
