oneact

One-act refers to a form of theatre in which a play is presented in a single continuous act. A one-act play is typically shorter than a full-length drama, with running times commonly ranging from about 15 to 60 minutes, though there is variation by country, festival, and author. The form emphasizes concise storytelling, often focusing on a specific moment, relationship, or idea, and it usually features a smaller cast and simpler production requirements than longer plays.

History and usage: The one-act form developed in the 19th century as audiences and venues sought shorter dramatic experiences. It gained particular traction in the 20th century, especially in schools, community theatres, and repertory companies, where it served as both a training ground for writers and a flexible programming option. Today one-acts are widely used in theatre education and in festival programming around the world, frequently presented in programs that juxtapose several short pieces.

Form and characteristics: One-act plays tend to be tightly structured, with a clear arc that unfolds within a single act and without an intermission. They typically employ a small cast and minimal settings, which allows for focused character exploration and rapid pacing. Thematic range is broad, spanning comedy, drama, satire, and experimental work. Because of their brevity, one-acts are often used to test new writing styles, to present complementary pieces in a single program, or to explore ideas that may be developed into longer works.
