In this study, the discussion about the change of emotion assumes that the notions of feeling, cross-feeling, and emotion are separate. Under this premise, I make a condition of periodization with the class of enjoyment and the background of the age and society in Hyangga, Goryeo songs, Akjang, Gyeonggichega, Sijo, and Gasa.
Moreover, I tried to grasp the emotional aspect of the period derived from it. Therefore, by considering the history of the Genre of Korean classic poetry through the change of emotion, I wanted to make a hypothesis that the change of Genre could be influenced by relations among emotional things.
For this, first of all, I examine the creation of Genre or general conditions of change. And I could find that 'the difference' of preceding Genre is in the center of these conditions, not the commonality. The present writer thought this difference is the change of emotion.
It is right to discuss emotion, feeling, and reason in literature. However, the discussion of emotion which is a notion to unify of emotion, feeling, and reason is insufficient yet because the accurate discussion about emotion is insignificant. In spite of this, the purpose of this study in this article is to search possibilities of writing of the history of Literature.
