Metric Structure of Korean Traditional Music by Common Rhythmic Patterns in Changdan

In Korean traditional music, the temporal unit corresponding to a fast beat is usually written in one square of the chŏngganbo notation, while the larger temporal unit corresponding to a group of such beats is written in a column of these squares. If we refer to the temporal unit corresponding to a single square as a common beat, the larger temporal unit may be called the large beat, and each of these may be felt as a beat on a different level. Moreover, just as the common beat may be subdivided into smaller beats, the large beat may be grouped into still larger temporal units, as I have shown elsewhere. In Korean music, a certain rhythmic pattern performed at a certain tempo is called a changdan, and this is the traditional way of conceptualizing rhythm. But if we refer to the most characteristic rhythmic pattern of a certain changdan as a common rhythmic pattern, we find that one changdan may correspond to more than one common rhythmic pattern or vice versa. Thus, there is a certain irrationality in the traditional usage of Korean musicians, which fails to identify a distinct temporal unit. This study proposes a solution to this problem by treating the common rhythmic pattern, rather than the changdan, as the basic unit.
