《汉书·传·扬雄传上》
风吹鼓帷帐，幽隐深静。阴阳清浊穆羽相和，好比夔、牙在调琴。般、棰扔了他们的刀凿，王尔丢掉其钩绳。
惟弸彋其拂汩兮，稍暗暗而靓深。阴阳清浊穆羽相和兮，若夔、牙之调琴。般、倕弃其剞厥兮，王尔投其钩绳。
The wind swells the curtains, secluded and peaceful. The clear and turbid sounds of yin and yang blend, like Kui and Ya tuning the strings. Ban and Chui abandoned their chisels, and Wang Er abandoned his hook and line.
