Dramatic structure (also called Freytag's pyramid) is the structure of a dramatic work such as a play or film. Many scholars have analyzed dramatic structure, beginning with Aristotle in his Poetics (c. 335 BCE). This article focuses primarily on Gustav Freytag's analysis of ancient Greek and Shakespearean drama.
In his Poetics, the Greek philosopher Aristotle put forth the idea that "A whole is what has a beginning and middle and end" (1450b27). This three-part view of a plot structure (with a beginning, middle, and end – technically, the protasis, epitasis, and catastrophe) prevailed until the Roman drama critic Horace advocated a 5-act structure in his Ars Poetica: "Neue minor neu sit quinto productior actu fabula" (lines 189-190) ("A play should not be shorter or longer than five acts").
Renaissance dramatists revived the use of the 8-act structure. In 1863, around the time that playwrights like Henrik Ibsen were abandoning the 5-act structure and experimenting with 3 and 4-act plays, the German playwright and novelist Gustav Freytag wrote Die Technik des Dramas, a definitive study of the 5-act dramatic structure, in which he laid out what has come to be known as Freytag's pyramid. Under Freytag's pyramid, the plot of a story consists of five parts: exposition, rising action, climax, falling action, and dénouement//revelation/catastrophe.
