Chilseok Nori (Kor. 칠석놀이, lit. Seventh Evening Play) refers to a series of folk performances that take place as part of the Chilseok celebrations (Kor. 칠석, Chin. 七夕, the seventh of the seventh lunar month). These consist of Gilnori (Kor. 길놀이, Opening Parade), Hapgung Nori (Kor. 합궁놀이, Consummation Play), Hwangsaesaem Chigi (Kor. 황새샘치기, Stork Well Cleaning), Chilseonggut Nori (Kor. 칠성굿놀이, Seven Stars Ritual), Gyeonu Jingnyeo Sangbong Nori (Kor. 견우직녀 상봉놀이, Performance of Reunion of the Ox Herder and the Weaving Maid), and Jangchigi Nori (Kor. 장치기놀이, Play with a Club). Festivals under various names and exhibiting regional variation were held in many parts of the country. Some examples include the Chilseok Nori of Busa-dong, Jung-gu, Daejeon City; the Chilseok Nori of Alchon and Hagye Villages in Buseo, Gimhae-gun, South Gyeongsang Province; the Songgye Nori (Kor. 송계놀이, lit. Pine Valley Play) of Jinaksan, Geumsan-gun, South Chungcheong Province; the Pungnyeonje (Kor. 풍년제, lit. Festival for Abundant Harvest) of Bugok-ri, Songsan-myeon, Dangjin-gun, South Chungcheong Province; and the Solbul Nori (Kor. 솔불놀이, lit. Pine Torch Play) of Jeong-eup, North Jeolla Province.
Chilseok Nori of Busa-dong, Jung-gu, Daejeon is related to the seasonal rituals that pray for the vigorous growth of crops and other farm produce. The performance is based on a local folk tale of a young couple, Buyong and Sadeuk; the tale is very similar to the story of the Cow Herder and the Weaving Maid. Celebrations involve a ritual held to pray for a good harvest, peace, safety, and the unity of two rival villages. This celebration is unique in that it combines a folk tale with seasonal customs producing an exciting form of folk performing art.
