Rhythmic Analysis of Jungjungmori in Sin Kwaedong-ryu Geomungo Sanjo

This study analyzes the rhythmic structures of the Jungjungmori jangdan in the Shinquae-dong style Geomungo Sanjo. Jungjungmori, a medium-tempo jangdan in Sanjo, balances tension and release through the combination of duple, triple, and mixed beats, showcasing distinctive rhythmic characteristics. The study categorizes various rhythmic patterns and investigates their structural features and roles. Additionally, rhythmic elements such as “Milbutim” are further identified to explore their roles in transitions and rhythmic expression. The analysis reveals that the duple beat provides a simple yet stable rhythmic pattern, reinforcing the structure of the piece and often appearing at the beginning or in stable sections. The triple beat contributes to creating tension and dynamically drives the progression of the music, enhancing its expressive power. The mixed beat harmonizes the duple and triple beats, balancing tension and release while enriching rhythmic diversity. Milbutim plays a key role in transitions and connections, forming unique and multi-layered rhythmic structures. These findings highlight that the Jungjungmori jangdan in the Shinquae-dong style Geomungo Sanjo retains the foundation of traditional jangdan systems while exhibiting creative and organic rhythmic characteristics. This study academically illuminates the rhythmic features of Shinquae-dong Sanjo and provides fundamental resources for the deepening and expansion of traditional music rhythm studies.
