The purpose of this study is to discuss the concept of storytelling and basic academic tasks for research on storytelling and to examine the methods of writing shamanic epics by taking them as an example of research on storytelling. Storytelling focuses on producing narrative works as a part of structural narratology. Previously, structural narratology involved the use of hermeneutics to dissect a narrative structure, but recently, storytelling has been characterized by employing premade narrative works and exploring theory and practice to produce new narrative works. Storytelling is the behavior of telling a story that has been widely distributed and practiced in traditional communities of China or the Korean Peninsula. It includes narrative shaman songs sung by a female shaman in the field of gut (exorcism), storytellers’ tales or novel reading, and master singers’ performance of pansori. Today’s storytelling too may seek implications about principles and methods from these precedents. Narrative is a mode of producing meaning while the agent moves around within a particular time and space. To investigate this, it is necessary to explore the agent, movement, characteristics of time and space, and interest induced by that movement. As a basic task for storytelling, this study examines the concepts and characteristics of these elements. Regarding the principle of storytelling in shamanic epics, first, the nuclear narrative develops with the repetition of marriage and childbirth. This reveals the primitive narrative that represents the principle that humankind continues to survive through marriage and childbirth. The method of writing the text for a shamanic epic is characterized by exclusively inserting and applying unit saseol transmitted from a long time ago according to the aspects of the narrative. This study uses as an example to understand the principle of creating poems in detail. This is because the principle of writing poems, widely known as oral formulae theory, has been introduced into storytelling.
