The Use of Diegetic Sound in Building Film Narrative Tension

Quick fact

In Alfred Hitchcock's 'Psycho,' the famous shower scene uses almost no music—only the diegetic sounds of water running, the knife slashing, and the victim's screams—creating a raw, visceral terror that still haunts audiences today.

Why this is interesting
