《宋书·志·卷十一》
冬至时阳气开始上升，乐均的声音清亮，圭表的表影最长，黄钟与气相应而贯通，土炭变轻而使其所在的杠杆端上抬。
冬至阳气应，则乐均清，景长极，黄钟通，土炭轻而衡仰。
During winter solstice, yang energy begins to ascend, the notes of the ensemble are clear and piercing, the sundial's gnomon's shadow is at its longest, and the pitch's Huang Zhong connects and resonates, and the weight of the soil decreases and causes its end to rise on the balance.
