This study aims to identify the social function of dance and to formulate the conceptual scheme of the social function of dance on the basis of Parsons’s (1972) theory of social system. The theory of social system articulates four functional imperatives so that a sub-social system survives and develops within inter-related atmosphere of all sub-social systems. The functional imperatives are adaptation, goal attainment, and latent pattern malntenance and tension management. The four functional imperatives provide the basis of conceptual framework to identify the social function of dance. Also the anthropological analysis of the relationships between dance and society. and the analysis of the purpose of dance, the functional classification of dance were used to formulate the conceptual scheme of social function of dance. Five social functions of dance were identified on the basis of the above analysis, They are socio-emotional function, socialization function, social integration function, religious function, and function of characterizing cultural identity. The socio-emotional function of dance includes three sub-functions of creation of joy, catharsis of emotion, and heightening of physical vitality. The socializing function of dance performs internalization of dorminant values of society into consciousness structure of individual in the society. The social integration function of dance includes three sub-functions of heightening sociablility of participants, formulating common interests among the people, and creating solidarity and unity of nation. The religious function of dance includes three sub-functions of contributing to Gods, praying for fortune, and experiencing religious ecstasy Finally, the dance’s function of characterizing cultural identity play the role of differentiating the belief system of one nation from another.
