Introduction:  Sound


We often say, “We are going to see a movie” and “I am watching a movie.”  These statements all focus on the visual aspect of film.

However, we should not underestimate the importance of sound (and the absence of sound) in film.  What we hear contributes greatly to our experience as members of the audience

Diegetic Sound


Diegetic sound arises naturally from the action of the film.  For example, you may hear characters speak to each other (dialogue) or a door slam.


WHAT’S THE EFFECT?


When we hear diegetic sound, we share the characters’ experience.  We hear what they hear.

Non-diegetic Sound


Non-diegetic sound arises from outside the action of the film.  Think of a film’s music soundtrack or voice-over (when a narrator addresses the audience, but the characters cannot hear what is said).  Non-diegetic sound is added in post-production, after the shots have been filmed.

WHAT’S THE EFFECT?


When a character or narrator provides a voice-over, it can create tension because we know something the other characters in the scene do not. A cleverly chosen song, playing at a key moment in the film, can create humour or contribute to the mood.
