The purpose of this study was to investigate the significance of Mu-ui (舞義, ritual of dance) by Seong Gyeong-rin in dance history and its value as Holgi (笏記, scroll document). This study identified the characteristics of the Japanese colonial period Jangsaengboyeonjimu (長生寶宴之舞, Dance of longevity) by comparing the record in Mu-ui to that in Jeongjaemudogholgi (呈才舞蹈笏記, scroll document of court dances). First, the costumes of dancers were five colors, and second, the song Changsha expresses simplification and degraded expression. Third, there was a slight difference in composition at the end. Fourth, in the dance, the order of the nine-sided dance was all the same, so there was no big change, but dance details were added to Mu-ui or little details were recorded. Fifth, there was a change in notation, but most of them had the same meaning or dancing. Those findings indicate that Mu-ui by Seong Gyeong-rin has the following values and significance in the dance history. First, it holds its value as a Holgi of Yiwangjikaakbu (李王 職雅樂部, the downgrated insitution of Jangakwon). Second, it offers information about the changes of court dance by Yiwangjikaakbu during Japanese colonial period. Finally, it enables the reproduction of Yiwangjikaakbu’s court dance by Mu-ui.
