In the words of the Encyclopedia Britannica, melodrama, in Western theatre, refers to “sentimental drama with an improbable plot that concerns the vicissitudes suffered by the virtuous at the hands of the villainous but ends happily with virtue triumphant.” In the melodrama genre, emotion is exaggerated and plot and action are emphasized in comparison to the more character-driven emphasis within a drama. Melodramas can also be distinguished from tragedy by the fact that they are open to having a happy ending, but this is not always the case. The melodrama focuses not on character development but on sensational incidents and spectacular staging.
Originally it was a genre of theatre in which music was used to increase the spectator's emotional response or to suggest character types. As technical developments in the theatre made greater realism possible, more emphasis was given to the spectacular—e.g., snowstorms, shipwrecks, battles, train wrecks, conflagrations, earthquakes, and horse races.
