This study exams the context, functioned as the background of Namdo Sori-pan(a performing place of folk song), in the side of 'Kkiwoneoki' (an insertion to upgrade a folk song) and 'Gyeorugi'(Competition). The study considers that Kkiwoneoki and Gyeorugi is a basic frame to form Namdo Sori-pan, and according to this, Namdo Song(the whole folk song sung in Namdo) based on communities has been formed or changed. The study assumes that it is a music with the background of 'Pan(place)' to all Namdo songs including a 'Hyangtominnyo'(a folk song sung by specialists) like 'Jindo Arirang' and 'Dungdeung-ae Taryeong' as well as Namdo-japga (a folk song sung by normal people) and Pansori(a traditional Korean narrative song). The study considers that the operation of Pan was a public share as the Hyangtominnyo. Nevertheless, by periodic or cultural changes, the public role has been entrusted according to a genre. In case of the genre that the entrustment is larger, the making arts is more progressed by a pulling and pushing competition. The study considers that this is a mental manifestation to try to be faithful to the role of an entrustment. That is, this thought is that the rule, operating a Pan through a visible competing composition, is sublimated in arts to insert, pull, and push, and then the rule can become a current Pansori. In this way, Kkiwoneoki and Gyeorugi are the basic rule to operate Namdo Sori-pan. When this Gyeorugi(competition) is deepened, the competition can induce the catharsis of a confusion and disorder with more pulling and pushing. Thus, it can be said that Namdo Song as 'Pan' has the characters of a confusion, a disorder, and a 'Sinawi'(an atypical instrumental music), involved a festive character. The character of a confusion and disorder may function as the mechanism to offer an ultimate catharsis in a sori-pan like Ssitgimgut(a shaman ritual for cleaning dead person’s soul) or a village festival. The character of Sinawi starts fromthe musical form made by Kkiwoneoki and Gyeorugi in the Pan where Namdo Song operates. In other words, it can be said that 'Pansori' is to be made an arts as a vocal music by the competition of the confusion and disorder, and 'Pan' Music is to be made an arts as instrumental music by it. Therefore, Namdo Sori-pan can be said to the contents and themedia that generate, change, and develop the operating way of Namdo people's Kkiwoneoki and Gyeorugi with the background of public 'Pan'.
