Originally, tsuzumi was a general term for drums in Japanese. Nowadays, hourglass-shaped drums are called tsuzumi. It was originally introduced as one of the instruments for gagaku (Japanese court music and dance). From drums called ikko, niko, sanko, shiko, it is said that niko was played by miko (shrine maiden) in Heian period. It is said that it was introduced into noh play through kusemai dance and became otsuzumi after it was used by shirabyoshi (female dancers). It is used for noh play, kabuki theater, folk performing arts. It has about 30cm in length. Body is made of quality cherry wood and skin is horsehide. The player holds the rope by left hand and hits one side of the head by right hand while setting on the left knee. Before assembling it, the player roasts the skin and makes it dry and tension. The sound becomes higher than usual by roasting the skin.
