Sound is an essential way to construct and define space in film. A film's sound-space is often called its soundscape and is made up of diegetic and non-diegetic sounds. A film soundscape can expand space off-screen or can project the internal space of a character. It can isolate sounds pertinent to the narrative (formalist) or it can record sound as it occurs (realist).
Select a scene and describe its soundscape. How is space constructed through the use of sound? Are the sounds diegetic or non-diegetic? Is the soundscape formally or realistically designed? How does the soundscape propel the narrative and/or comment on characters?
