Tegoto is a long part of instrumental music sandwiched between vocal music in a piece by an instrumental trio, which is a collective term for jiuta (a genre of traditional songs with accompaniment by shamisen (three-stringed lute)), sokyoku (koto (thirteen-stringed Japanese zither) music), and kokyugaku (Chinese fiddle music).
