Act (drama)
An act is a major division of a theatre work, including a play, film, opera, or musical theatre, consisting of one or more scenes. The term can either refer to a conscious division placed within a work by a playwright (usually itself made up of multiple scenes) or a unit of analysis for dividing a dramatic work into sequences. As applied, those definitions may or may not align. The word "act" can also be used for major sections of other entertainment, such as variety shows, television programs, music hall performances, cabaret, and literature. Acts and scenes. An act  is a part of a play defined by elements such as rising action, climax, and resolution. A scene normally represents actions happening in one place at one time, and is marked off from the next scene by a curtain, a black-out, or a brief emptying of the stage. To be more specific, the elements that create the plot of a play and divide it into acts include the exposition, which gives information, setting up the rest of the story. Another element is the inciting incident, which starts all the action that will follow. Going along with the inciting incident , the major dramatic question is formed, which holds the rest of the play. The majority of the play is made up of complications, which change the action. These complications lead to the crisis, which is the final plot point. At this point, the major dramatic question has usually been answered. Finally, there is "the resolution, also known as the denouement", which is the end of the play, where everything comes together and the situation has been resolved, leaving the audience satisfied with the play as a whole. These more specific elements of plot are the main things used to divide  a play into acts and sometimes scenes, Sometimes the play may not end as a resolved situation, it may leave the audience on a peak and have a sequel to it. Though there is no limit to the number of acts in a dramatic work, some may have been derived from different interpretations of Aristotle's "Poetics", in which he stresses the primacy of plot over character and "an orderly arrangement of parts" and others may have been derived from Freytag's Pyramid. History. Roman theatre was the first to divide plays into a number of acts separated by intervals . Acts may be further divided into scenes. In classical theater, each regrouping between entrances and exits of actors is a scene, while later use describes a change of setting. Modern plays often have only one level of structure, which can be referred to as either scenes or acts at the whim of the writer, and some writers dispense with firm divisions entirely. Successive scenes are normally separated from each other in either time or place, but the division between acts is more to do with the overall dramatic structure of the piece. The end of an act often coincides with  one or more characters making an important decision or having an important decision to make, a decision which has a profound impact on the story being told. Contemporary theatre, in line with screenwriting and novel forms, tends towards a three-act structure. Many operettas and most musicals are divided into just two acts, so, in practice, the intermission is seen as dividing them, and the word "act" comes to be used for the two-halves of a show whether or not the script divides it into acts. Varieties. One-act plays. A one-act play is a short drama that  consists of only one act; the phrase is not used to describe a full-length play that does not utilize act-divisions. Unlike other plays which usually are published one play per book, one-act plays are often published in anthologies or collections. Three-act plays. In a three-act play, each act usually has a different mood. In the most commonly used structure, the first act has a lot of introductory elements (that is, who, what, when, where, why, and how); the second act is usually the darkest, with the antagonists having a greater compass; and the third act  has a resolution (dénouement), often with the protagonists prevailing. Five-act plays. Until the 18th century, most plays were divided into five acts. The work of William Shakespeare, for example, generally adheres to a five-act structure. This format is known as the five-act play, and was famously analyzed by Gustav Freytag in "Die Technik des Dramas" (Dramatic techniques). The five acts played specific functions in the overall structure of the play, but in performance, there was not necessarily any clear separation between them. A similar five-part structure is also used in traditional Japanese Noh drama, particularly by  Zeami Motokiyo. Zeami, in his work ""Sandō"" (The Three Paths), originally described a five-part (five "dan") Noh play as the ideal form. It begins slowly and auspiciously in the first part ("jo"), building up the drama and tension in the second, third, and fourth parts ("ha"), with the greatest climax in the third "dan", and rapidly concluding with a return to peace and auspiciousness in the fifth "dan" ("kyū"). Other media. As part of a television program, each individual act can be separated by commercials. In film, a number of scenes grouped together bring an audiovisual work to life . The three-act structure is commonly referred to in film adaptations of theatrical plays.
