Munmu is a type of Ilmu (line dance) performed during Confucian ancestral rites at the Munmyo shrine and the royal ancestral rituals at Jongmyo. It is danced to honor the civil virtues of the deceased, corresponding to Mumu, which praises martial achievements. At Jongmyo, Munmu is performed during the Yeongsin (welcoming of spirits), Jeonpye (presentation of offerings), and Chohon (first libation) stages of the rite.
As part of the Jongmyo Daeje (Great Ritual at Jongmyo), this dance employs ritual objects: in the left hand, dancers hold an yak (a bamboo flute with three holes made of yellow bamboo), and in the right hand, a jeok (a wooden staff decorated with pheasant feathers). The choreography begins with the dancers lifting their right foot and raising both arms as if carrying something on their shoulders, followed by bowing forward while lowering their arms. These movements are performed first facing north, then west, east, and back north again, repeating the same sequence to the solemn rhythm of the music.
