The patterns of describing the scene that Mong-Ryong and Choon-Hyang establish ralations in Choon-Hyang-Ga, were originated from those of seosamuga(서사무가), especially Je-Seog-Bonpuri(제석본풀 이). The patterns of describing the scene that man and woman establish relations in Choon-Hyang-Ga are similar to those of Je-Seog-Bonpuri, as both receive usefully unit-words from Seong-Jo-Ga(성조가). And, pansori and seosamuga are subordinate to oral narrative poetry. So, in the evolutionary piont of view, I think that those of Choon-Hyang-Ga were originated from those of Je-Seog-Bonpuri. In the early stage, oral poets described cheerfully the scene that man and woman establish relations in Choon-Hyang-Ga, using unit-words from Seong-Jo-Ga. But gradually, oral poets try to describe the scene sorrowfully and try to stress on person`s mental state. In the long run, the affair that man and woman establish relations in Choon-Hyang-Ga inclines to the truly human affair. This is a sign of modern-inclination.
