한국전통음악의 장단 연구사

Abstract

Changdan 長短 (lit. long and short) is used as a term related with rhythm in Korean traditional music. Though it was difficult to study since the term was used in a sophisticated way, the research on changdan was done by many scholars from the 1950s when the Society for Korean Musicology (韓國國樂學會) was established throughout today. The studies on changdan by Korean musicologists are classified into two. The first is about the characteristics of changdan itself. The second is about the musics in particular changdan, which is in greater numbers than the first. The study of changdan was started by Lee Hye-ku 李惠求 [Yi Hye-gu] and Chang Sa-hun 張師勛, scholars of the first generation of Korean musicology. They tried to study the characteristics of music by researching changdan of the music. Yi Po-hyŏng 李輔亨, a scholar of the second generation, continued their study of changdan. He made clear the characteristics of composition of different levels of beat in the rhythmic cycle of changdan, which distinguishes different changdan from each other. He also established a theory that determines the cycle of changdan by clarifying synthetic structure of rhythm with the structure of combination of rhythms of different levels. He also examined the musical meaning that the rhythmic type of changdan has in music in many different rhythmic types. In the next generation after Yi Po-hyŏng, many scholars are active in examining the characteristics of changdan.
