The inversion is Diegetic Switch, when the music goes from in-universe to soundtrack.
Contrast Medium Awareness, for when a character is actually hearing the soundtrack. Not related to Leave the Camera Running, where the camera is set in the same scene for a very long time even if nothing's happening. Compare Diegetic Visual Effects, its visual counterpart.
A humorous variation of Source Music (which is any instance where the music the audience hears is actually in the scene).Ĭompare Diegetic Soundtrack Usage, for when the show's theme tune is performed within the show. Bonus points if a second character apologetically turns the music off.
Meta-joke wherein the Background Music builds to a dramatic pace, and one of the characters suddenly turns around and complains about the loud music revealing that what you thought was part of the soundtrack was music actually playing in the show.
