Kibigaku is the composite art with music and dance, which was founded by Yoshihide Kishimoto, a Gagaku musician of former Okayama domain in 1872. Kibigaku was performed when Munetada Shrine in Omoto, Okayama City was built. And since then, Kibigaku has been the official ritual music of Kurozumikyo (a type of Japanese religion).
Gagaku was made up of music and dance of Asian countries and those of ancient Japan. Its base was established in around the 10th century and has been passed on until now in various ways. Gagaku has been performed as the music for the court and religious ceremonies.
