Note that the innovative tuning method developed by Kengyo YOSHIZAWA and compositions based on it aimed at going back to the beginnings of koto music, and the lyrics to the music were often used from the waka of Kokin Wakashu (A Collection of Ancient and Modern Japanese Poetry), and so this music is sometimes seen as being reactionary.
なお、吉沢検校による革新的な古今調子の考案や、それに基づく作曲は、箏本来の曲を目指したこと、曲の歌詞などに古今和歌集の和歌を多用したことなどから、復古主義と呼ばれることもある。
