What are the requirements for the materials used to make drumsticks and sticks?

Drumsticks in the Tang Dynasty were generally made of Dalbergia odorifera, dog bones, pepper and other wood. Wood must be dry, so as to prevent moisture and make it flexible and greasy. Only when the wood is dry, the drums are crisp and loud, and satiny is the hoofbeat of the Jie drum like a horse running. Hard iron should be used when drawing drums. Iron should be refined and rolled evenly. If the iron is not rigid, the edge of the drum will be uneven and elastic, so the sound made by the drum will not conform to the rhythm.
