Peter Brook, a prominent theater director, has said, “ For theater to take place, an actor walks across an empty space while someone else is watching.” This is a very simple and clear definition for theater. In other words, theater is indicates that in a specific space and time, actors perform in front of audience. According to this definition, it seems that little children’s game of playhouse, the singing class in primary high school or the common talk on the street will be included. If we regard those activities as theater, perhaps it will make us confused confuse us when in discussing theater. For the purpose, we don't think those activities theater. we don’t think of those activities mentioned above as non-dram. but those which can be identified as events and activities aimed at performance itself.

II Drama and theater

We have to distinguish two terms first: Drama drama and theater theatre / theatrical art. Generally speaking, drama and theater are basically equivalent. They mean all the performances on a stage, and that is also what we introduce in this site. But if we distinguish more strictly, drama a genre of western literature, characteristically literal. In other words, people often make a distinction between drama, which concerns the written text, or script, for the performance, and theater, which concerns the performance of this script. So the theaters we introduce here means: performances, which are performed by people on formal stages.
