This study aims to analyze dance moves of Munmu and Mumu, two kinds of Ilmu of Jongmyojerye (the royal ancestral rites music) in order to identify significance and symbolism of the dance moves. The findings show that "Gyeonpa" was a dance move that was always included in 11 pieces of Botaepyeong(music to praise the cultural achievements of Jeseon's kings) and Jeongdaeeop(Music to extols the military attainments of Jeseon's kings) each. In Munmu, dancers would collect the energy, which has been circulated and spread before their faces with the knees bending and stretching and two hands open sideways each of the pieces by performing dance moves of spreading, gathering, turning, and repeating in most cases. After this Gyeonpa, the dancers expresses symbolically the wish for Botaepyeong, which achieves unity between the Heaven and Earth and hopes for a reign of peace for many years, in attitudes of respect and humility. In Mumu, they would maintain the Gyeonpa move of erecting a wooden sword(spear) straight and raising it high during long beats through the arm movement with no knee bending and stretching or perform Hyeokjeong with power and discipline 12 times, expressing Uideok(virtue) symbolically. The dance move of Gyeonpa is representative of the unique nature of Jongmyoilmu. It is important that the moves of spreading Mundeok in the combination of Yak and Jeok, circulation of yin and yang, and harmony of Ye and Ak would connect to flexible and soft dance moves of Haphyung in Munmu. In Mumu, it is important to maximize the solemn mood by erecting the wooden sword(spear) straight and stopping it with moves of embodying the achievements of distinguished military service with discipline.
