Korean traditional dance is a well-established traditional art as years go by. Recently, Korean traditional dances have seen renewed popularity, but in the process, new interpretations and transformations have eroded the historical and spiritual values inherited in these traditional dances. This study is to rediscover these historical and spiritual values by re-examining the life and dance philosophy of Han Sung-Jun (韓成俊, 1874-1941), and how these had been handed down to Han Youn-sook and Lee Ae-ju. The research reviews existing literature with comprehensive and in-depth analysis. Han Sung-Jun, who came from a long line of dance artists who inherited and developed dance practices reflecting the unique identity of the Korean people, believed that it was through dancing that the human body could truly manifest its natural vitality and emphasized patient learning and training. Han Sung-jun's philosophy was passed on to his granddaughter, Han Young-sook (韓英淑, 1920-1989), who emphasized the exclusion of foreign imitation and of exaggeration by utilizing the spontaneous characteristics of Korean dance. She particularly criticized the blind following/copying of foreign dances and emphasized a focus on traditional Korean dances. Lee Ae-ju (李愛珠, 1947-), who in turn inherited the school of thought from Han Young-sook, took the view that it was through dance training that the mind and soul could have release towards full realization of the human nature. She emphasized the training that all of the body's energy sprang from the lower abdomen to introspect within oneself and served as the foundation for all Korean traditional songs and dance.

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.
