《荀子·乐论》
拿着盾牌斧头等舞具来跳舞，用野鸡毛和牦牛尾等舞具做装饰，用石磬、箫管来伴奏。所以那乐声的清朗像天空，广大像大地，那舞姿的俯仰旋转又和四季的变化相似。
唱和有应，善恶相象，故君子慎其所去就也。君子以钟鼓道志，以琴瑟乐心；动以干戚，饰以羽旄，从以磬管。故其清明象天，其广大象地，其俯仰周旋有似于四时。
Holding shields, axes and other dance props, and using wild chicken feathers and yak tails as props, and playing stone chimes and pipes as accompaniment. Therefore, the music is as clear as the sky and as vast as the earth, and the dance postures of looking up and down and spinning are similar to the changes of the four seasons.
