The subject of this study was Sasangjwa dance, the first part of the Bongsan mask dance, which is designated as No. 17 of the National Intangible Cultural Properties. The Sasangjwa dance is composed of dances that have no lines. Four sangjwas pray for the audience’s well-being and fortune, and at the same time, purify the stage by bowing to the Four Symbols. The dance is ceremonial and has characteristics of Byeoksajingyeong(which means to defeat bad things and approach good things. The Bongsan Mask-dance Drama Preservation Society’s regular performance has occurred continually for the past 69 years. Although the National Intangible Cultural Properties’ diverse activities have been performed for about 70 years, only a small amount of academic research on the first section of the Bongsan mask dance, the Sasangjwa dance, has been conducted. In addition, the terminology of the Bongsan Sasangjwa dance steps has not been established; therefore, linguistic communication is difficult in educational courses on the Sasangjwa dance. Accordingly, this study aims to record and arrange the Sasangjwa dance academically, present its dance scores, and establish terms for its dance steps, thereby providing a reference for future research. The terms for the dance steps of the Sasangjwa dance are indexed and arranged based on Akhakgwebeom and Jeongjaemudoholgi. Existing research has considered folklore mask dances to be irrelevant to Jeong-jae. However, this study considered the Sasangjwa dance according to its dance steps, formation, and scores and used Jeong-jae terminology to describe them. In the process, it was discovered that Jeong-jae terminology is implicative and uses referential and figurative language; this terminology was particularly convenient to explain the dance steps of the Sasangjwa dance, since the characteristics of traditional Jeong-jae were handed down to gisaengs, who adopted the Sasangjwa dance. During Japan’s colonial era, the Sasangjwa dance was performed by gisaengs at regional offices in place of the existing male mask dancers; as a result, the Sasangjwa dance was transformed into a feminine dance that was in obvious contrast with the Mokjoong dance. In this paper, the aim of establishing of dance step terminology for the Bongsan Sasangjwa dance was to facilitate the education of students and communication in general about the Sasangjwa dance.
