This study aims to examine the aesthetic resonance principle of Korean dance by analyzing how the place of Korean dance in the Middle Ages was influenced by the effect of dance through the ‘ki (氣, energy)’ theory by philosopher Choi Han-gi (1803~1879). As a research method, records related to dance were selected from historical literature, and Choi Han-gi's books were used as main texts, and related discourses were referenced. The original texts of the old documents used online databases with major old documents such as the National History Compilation Committee database, and keywords were limited to ‘mu (巫, shaman)’, ‘mu (舞, dance)’, and ‘chum (춤, dance)’. The results of the study are as follows. First, Korean dance was organically adapted to the spacetime of traditional society. Second, it was confirmed that the space of life was entangled as a place of dance in the traditional society. Third, it was possible to aesthetically explain that the principle of resonance in a special space called “sai (사이, between)” among dance places in traditional society was in ‘communication’. The main keywords of this study ―placeness, resonance, singi (神氣, primal energy), communication― are concepts that share the meanings of resonance as the nature of dance. The keywords are expected to contribute a academic and practical direction for today's dance theory.
