 Taiko construction has several stages, including making and shaping of the drum body (or shell), preparing the drum skin, and tuning the skin to the drumhead. Variations in the construction process often occur in the latter two parts of this process. Historically, byō-uchi-daiko were crafted from trunks of the Japanese zelkova tree that were dried out over years, using techniques to prevent splitting. A master carpenter then carved out the rough shape of the drum body with a chisel; the texture of the wood after carving softened the tone of the drum. In contemporary times, taiko are carved out on a large lathe using wood staves or logs that can be shaped to fit drum bodies of various sizes. Drumheads can be left to air-dry over a period of years, but some companies use large, smoke-filled warehouses to hasten the drying process. After drying is complete, the inside of the drum is worked with a deep-grooved chisel and sanded. Lastly, handles are placed onto the drum. These are used to carry smaller drums and they serve an ornamental purpose for larger drums.
