Shōmyō

Shōmyō (声明) is a style of Japanese Buddhist chant, used mainly in the Tendai and Shingon traditions. There are two styles: ryokyoku (呂曲) and rikkyoku (律曲), described as difficult and easy to remember, respectively.

Shōmyō, like gagaku, employs the yo scale, a pentatonic scale with ascending intervals of two, three, two, two, and three semitones.
