Drama is the specific mode of fiction represented in performance.Elam (1980, 98). The term comes from a Greek word meaning "action" (Classical Greek: , dráma), which is derived from "to do" (Classical Greek: , dráō). The enactment of drama in theatre, performed by actors on a stage before an audience, presupposes collaborative modes of production and a collective form of reception. The structure of dramatic texts, unlike other forms of literature, is directly influenced by this collaborative production and collective reception.

The two masks associated with drama represent the traditional generic division between comedy and tragedy. They are symbols of the ancient Greek Muses, Thalia and Melpomene. Thalia was the Muse of comedy (the laughing face), while Melpomene was the Muse of tragedy (the weeping face).

The use of "drama" in the narrow sense to designate a specific type of play dates from the 19th century. Drama in this sense refers to a play that is neither a comedy nor a tragedy--for example, Zola's Thérèse Raquin (1873) or Chekhov's Ivanov (1887). It is this narrow sense that the film and television industry and film studies adopted to describe "drama" as a genre within their respective media. "Radio drama" has been used in both senses--originally transmitted in a live performance, it has also been used to describe the more high-brow and serious end of the dramatic output of radio.

Drama is often combined with music and dance: the drama in opera is sung throughout; musicals include spoken dialogue and songs; and some forms of drama have regular musical accompaniment (melodrama and Japanese Nō, for example).See the entries for "opera", "musical theatre, American", "melodrama" and "Nō" in Banham (1998). In certain periods of history (the ancient Roman and modern Romantic) dramas have been written to be read rather than performed.While there is some dispute among theatre historians, it is probable that the plays by the Roman Seneca were not intended to be performed. Manfred by Byron is a good example of a "dramatic poem." See the entries on "Seneca" and "Byron (George George)" in Banham (1998). In improvisation, the drama does not pre-exist the moment of performance; performers devise a dramatic script spontaneously before an audience.Some forms of improvisation, notably the Commedia dell'arte, improvise on the basis of 'lazzi' or rough outlines of scenic action (see Gordon (1983) and Duchartre (1929)). All forms of improvisation take their cue from their immediate response to one another, their characters' situations (which are sometimes established in advance), and, often, their interaction with the audience. The classic formulations of improvisation in the theatre originated with Joan Littlewood and Keith Johnstone in the UK and Viola Spolin in the USA. See Johnstone (1981) and Spolin (1963).
