Beat
A beat is the smallest unit of story — a single moment of change, decision, or shift in a character's emotional position. Writers also use "beat" as an in-script pause, written on its own line, to mark a held moment in dialogue. In both senses it is the basic pulse of dramatic action.
In story terms, a beat is one exchange of action and reaction — the unit a scene is built from. A scene is a sequence of beats; a sequence is a run of scenes; the screenplay is the sum.
On the page, "(beat)" or "beat" on its own line marks a pause — a held silence inside a speech or between lines. It is a timing instruction, not a story beat, and the two meanings live side by side in working vocabulary.
