The purpose of this study is to investigate the value and effect of Myeongjakmu as cultural contents and to study development measures for revitalization. A total of eleven experts, including eight original performers and successors of Myeongjakmu and three dance performance planners and administrators, were interviewed in both unstructured and semi-structured ways. Based on the data collected from the interviews with these experts, two areas of Myeongjakmu – its creative values and its ripple effects – emerged to serve as cultural contents. Music, dance moves, costumes, and props were categorized into the creative value area, while popularization, consensus formation, and accessibility were classified into the area of ripple effects. In this article we propose four development plans to revitalize Myeongjakmu based on the experts opinions. Establishing the status of Myeongjakmu, policy support, deepening expertise, and securing sustainability. These actions will increase the value of the disappearing Korean dance cultural heritage as a systematic study for future Myeongjakmu, and contribute to the establishment of related knowledge systems and basic composition of transfer materials.
