Answer: -dramatic convention
Step-by-step explanation:
Dramatic conventions are the distinct actions and procedures the performer, writer and director can apply to conceive the wanted dramatic effect. They are a collection of rules which both the public and the artists understand.
Soliloquy, dramatic irony, character foil, and aside, are all different types of dramatic conventions. In this passage, the dimming of the lights and the music are technical conventions that provide information on the time of the day and the passing of time.
