Socio-cultural frontiers of the theater and games in the context of interdiscipline discourse

Considering the intersection of the concepts of play and theater in the interdisciplinary humanitarian discourse, the author substantiates the methodological productivity of the concept of sociocultural frontier, which allows us to consider the phenomenon of theater in its procession. The boundaries of the theater are mobile in terms of defining it as a temporal form of art in the cultural, historical and social aspects. But there are value-semantic limits beyond which he loses his essence and social function.
