The study looked into the environment in which Korean B-boying has developed into a dance drama with dramatic elements in it to enhance traditional culture and present its cultural relevance to Korean tradition. B-boying has been judged difficult to be developed into a performing arts with impromptu and resistance based on a dance battle. Voluntarily breaking this perception and presenting the world’s first dramatic dance, Korean B-boys, however, have become an international issue. These developmental factors were originated from Korean traditional culture and ethnicity. Korean dance drama was starting that the way as Koreans have loved singing and dancing in their life. From the Sanggo period to the Joseon Dynasty, ranging from singing and dancing to mask dance, it was eventually developed into a dance drama with perfect theatrical elements. Namsadang play is the only dance drama that has maintained its traditional form. It has been revealed that Ttangjaeju(Korean Traditional Ground Acrobatic) of Namsadang play is similar to that of B-boying. B-boying whose framework is a battle, is about who wins in competing dance and Ttangjaeju presents jesting between the Ttangjaeju player and the clown in a dramatic way. Since B-boying, born abroad, showing strong dance in the battle patterns, landed in Korea, it has been developed into a dance drama with dramatic elements. These cultural factors can be characterized by their long history that they are developed into dance dramas through dancing and singing. Therefore, Korean culture that loves dancing and singing suggests that the dramatic elements of Namsadang play and the environment in which Korean B-boying evolved into dance dramas are related to Korean traditional culture led to ethnicity.
