Empathetic Sound: Music whose mood or rhythm matches with the mood with the mood or rhythm of the action onscreen.

Anempathetic Sound: Sound–usually diegetic music–that seems to exhibit conspicuous indifference to what is going on in the film's plot, creating a strong sense of the tragic. For example, when a radio continues to play a happy tune even as the character who first turned it on has died.
