Gagaku (, literally "elegant music") is a type of Japanese classical music that has been performed at the Imperial court for several centuries. It consists of three primary bodies: native Shintoist religious music and folk songs, saibara, as well as a Korean and Manchurian form (more precisely, from the old Korean kingdom of Koma, with the Manchu influence being less direct), known as komagaku, and a Chinese form (specifically Tang Dynasty), togaku. By the 7th century, the gakuso (a zither) and the gakubiwa (a short-necked lute) had been introduced in Japan from China.
