This study was intended to explore the MyungJaLee’s Taepyeongmu movement principles and to study the somatic movement principles inherent in it by applying ‘BRACED’, the basic somatic movement principles in order to establish not only the external and formal beauty, but also the intrinsic value of dance and the movement principles inherent in Taepyeongmu and, based on this, to lay the educational foundation for the transmission and development of the traditional dance. The movement of Taepyeongmu stands out, compared to other types of traditional dances, in terms of the change of rhythm and the variety of movements in each stage. It derived the MyungJaLee’s Taepyeongmu movement principle based on the analysis of MyungJaLee’s Taepyeongmu based on ‘BRACED’, the somatic movement principle. All six principles of 'BRACED', including Breathing, Relaxation, Alignment, Connection, Expectation, and Dance, are inherent in MyungJaLee’s Taepyeongmu and appear differently for each stage. Based on this, if the MyungJaLee’s Taepyeongmu movement principles based on BRACED is well applied and utilized from the point of view of transmission practitioners and educators, it will be available to more intensively explore the essence of traditional dances, including Taepyeongmu, etc. Transmission practitioners should subdivide the role of Breathing to control it well, reflect their bodies well, and upright their bodies centered on the pelvis. In addition, they should always introspect about the dance based on the smart body and embodied learned with the assimilated, and when they conduct an education on the transmission of the traditional dance based on the above-mentioned principles, they should first educate the theoretical background of the traditional dance before educating on its movement and then proceed with the education focusing on the movement principles. The subject of study while utilizing the somatic movement principles systemized based on the West. A study on the traditional dance using somatic has the universality and utilization value as an analysis method for dance movements in a narrow sense and as basic data for preservation and transmission education in a broad sense. with this study as an opportunity, it is expected that it will provide an opportunity to think about the search for the essence of the traditional dance along with various studies on its movement principles.
