Komagaku

What it is

Komagaku is one branch of gagaku, the music of the Japanese imperial court. What marks it off from the other branches is the ensemble: it uses winds and drums, and leaves out the plucked strings heard elsewhere. Its pieces sit beside the court dances rather than standing alone, and the dance is usually where a listener meets them. The style draws its name and much of its melodic material from Koguryeo, one of the Korean kingdoms, though it was the Japanese court that shaped it into a fixed repertoire. A second gagaku branch, togaku, invites comparison, because the two differ in sound.

Origins and history

The style belongs to the early Heian period, when the court reorganized the music it had inherited and set it into formal categories. Music that had arrived from the Korean peninsula and nearby regions was sorted, renamed and folded into an official repertoire for the palace. A set of pieces traced to Koguryeo and to the other Korean kingdoms was known together as sankangaku, and komagaku grew out of that group. Two things gave the new category its shape: where its music came from, and which instruments played it. From then on it stayed close to particular ceremonies and dances of the imperial court.

Instruments and sound

A komagaku ensemble is made up of wind and percussion only. The komabue, a transverse bamboo flute, carries the melodic line. Three drums sit alongside it: the taiko, the kakko and the shōko. With no plucked string instrument in the group, the blend of sound differs from togaku, the other large gagaku style, where strings have a place. Rhythms tend to be lively, with firm percussive patterns, a quality that suits their use behind dancing.

Dance and performance

Most often komagaku is played for bugaku, the court dance. The dancers wear masks and elaborate costumes, and their movement is energetic and stylized, matched to the brisk drumming. These performances were once given at ceremonies of the imperial court, and they have continued in that setting. Imperial and cultural institutions in Japan are the bodies that preserve both the music and the dance today. Because the two are so tightly joined, a piece is usually understood as part of a staged ceremony rather than as concert music on its own.

Repertoire and change

Compared with the other gagaku styles, komagaku holds a small number of pieces. Many of them are thought to carry musical structures that came from ancient Korean court music, though centuries of use in Japan have altered them. The melodies were adapted as the court repertoire settled, so what survives is a Japanese reading of an older import rather than a copy of it. The tradition has stayed small and closely held, kept within the institutions responsible for the court's music.

How Komagaku is kept

The keepers are court musicians and dancers working within Japan's imperial and cultural institutions. In a performance the wind and percussion players take their places, the drums set a firm beat, and the flute lays out the melody. Masked dancers in elaborate costume then move through stylized, energetic steps timed to the music. What was once part of court ceremony is still staged in that setting, so the pieces are heard within a ceremony or a dance programme rather than as free-standing concert items.

When and where

Komagaku belongs to Japan, where it grew out of the court music system and remains part of it. Its home is the imperial court, and it is kept alive there by imperial and cultural institutions. The melodic material it draws on came from Koguryeo and other regions of the Korean peninsula, but the style itself took shape in Japan and is performed there.

What Komagaku means

For those who keep it, komagaku stands for a particular line of the court's musical inheritance. Its identity rests on two things the tradition itself marks: where the melodies came from, the Korean kingdoms, and how they are played, with winds and drums rather than strings. That pairing shapes how the style is set apart from togaku and why it belongs with the masked dances of the court.
