 The larger ō-tsuzumi and smaller ko-tsuzumi are used in the opening and dances of Noh theater. Both drums are struck using the fingers; players can also adjust pitch by manually applying pressure to the ropes on the drum. The color of the cords of these drums also indicates the skill of the musician: Orange and red for amateur players, light blue for performers with expertise, and lilac for masters of the instrument. Nagauta-shime daiko or uta daiko are also featured in Noh performance.
