 Taiko are categorized into three types based on construction process. Byō-uchi-daiko are constructed with the drumhead nailed to the body. Shime-daiko are classically constructed with the skin placed over iron or steel rings, which are then tightened with ropes. Contemporary shime-daiko are tensioned using bolts or turnbuckles systems attached to the drum body. Tsuzumi are also rope-tensioned drums, but have a distinct hourglass shape and their skins are made using deerskin.
