Gagaku

Gagaku (雅楽, gagaku?, ancient imperial court music and dances, lit. "elegant music") is a type of Japanese classical music that has been performed at the Imperial Court in Kyoto for several centuries. It consists of three primary repertoires:

1. Native Shinto religious music and folk songs and dance, called kuniburi no utamai
2. A Goguryeo and Manchurian form, called komagaku (named for Koma, one of the Three Kingdoms)
3. A Chinese and South Asia form (specifically Tang Dynasty), called togaku.

Gagaku, like shōmyō, employs the yo scale, a pentatonic scale with ascending intervals of two, three, two, two, and three semitones between the five scale tones.
