This study examines the aesthetic characteristics of the seungmu of Beopu Song Jaeseop, designated as the Intangible Cultural Heritage of Daejeon Metropolitan City. Having studied seungmu under Yi Maebang since 1989, Song Jae-seop established his own dance style by adding on his artistic interpretation. Through literature review, analysis of oral data, and comparative aesthetic analysis, this study identifies four aesthetic characteristics of this style. First, the beauty of inward restraint and condensation, which emphasizes stillness and breath before movement. Second, breath-centered physical expression, where deep and slow breathing determines the beginning and end of movements. Third, internal expression through jangsam (long-sleeved robe) that reveals the performer’s inner state rather than visual splendor. Fourth, the synthesis of locality and artistry formed by combining the aesthetic traits of Yi's style with Daejeon's regional characteristics. Consequently, this study confirms that the seungmu of Beopu Song Jaeseop is not a mere regional transmission of the Yi Maebang style, but a unique school reflecting the practitioner's performative life and artistic values.
