Scene (drama)

In drama, a scene is a unit of action, often a subdivision of an act. A scene is a dramatic part of a story, at a specific time and place, between specific characters.
French scene.
A "French scene" is a scene in which the beginning and end are marked by a change in the presence of characters onstage, rather than by the lights going up or down or the set being changed.
Obligatory scene.
From the French "scène à faire", an obligatory scene is a scene (usually highly charged with emotion) which is anticipated by the audience and provided by an obliging playwright. An example is "Hamlet" 3.4, when Hamlet confronts his mother.
