This study aims to provide a multidimentional reconstruction of the transmission landscape of city- and provincial-designated intangible heritage dance arts of the Seoul metropolitan and central regions, and to explore a sustainable transmission paradigm. To this end, a comprehensive survey of intangible heritage designations within the region was conducted, and a comparative analysis of the aesthetic characteristics of salpuri chum and seungmu was performed according to their respective lineages. The analysis revealed a severe geographical imbalance; dance genres are heavily concentrated in western plain areas such as Seoul and Gyeonggi, whereas eastern mountainous areas like Gangwon and Jungbuk show uneven transmission due to the absorption of dance elements into composite ritual genres. Nevertheless, even within the same genre, distinctive artistic identities have differentiated into classical beauty, ritual character, and aesthetic flexibility depending on master-disciple lineages and regional sensibilities. Accordingly, this study proposes practical alternatives combining multidimensional archiving of fragmented local dance assets with a communication strategy that employs media technology as a limited supplement. This study is significant in demonstrating that regional intangible heritage constitutes an independent value system that sustains the diversity of Korean dance, and in establishing the necessity of a diversified transmission paradigm.
