The most famous and perhaps most demanding of the narrative styles is gidayū, named after Takemoto Gidayū (1651–1714), who was heavily involved in the bunraku puppet-theater tradition in Osaka. The gidayū shamisen and its plectrum are the largest of the shamisen family, and the singer-narrator is required to speak the roles of the play, as well as to sing all the commentaries on the action. The singer-narrator role is often so vocally taxing that the performers are changed halfway through a scene.
