changdan

The term "changdan" refers to the rhythmic frameworks used in Korean narrative song, known as pansori. These rhythmic patterns, or jangdan, are distinguished by their beat structure, accents, and tempo, and they evoke specific emotional states within the performance. Different jangdan are employed to match the narrative, whether it depicts lamentation, enjoyment, agony, or suspense, and can even signify the appearance of mythical characters.1

Pansori itself is a traditional genre of Korean narrative song, typically performed dramatically by a vocalist accompanied by a drum called a buk. The name pansori combines "pan" (open space) and "sori" (singing), referencing the public venues where these performances originally took place. A pansori singer uses song, narration, and dramatic gestures to tell a story, while the drummer provides the rhythmic setting.1
