《宋书·志·卷十一》
《乐经》的残缺由来已久，坦墨在《汉书》中的叙述也就是从《乐记》中摘抄的，司马彪《后汉书》中又没有完备的续述。
《乐经》残缺，其来已远。班氏所述，止抄举《乐记》；马彪《后书》，又不备续。
The "Records of Music" has been incomplete for a long time. The narrative in Ban Gu's "Records of the Han Dynasty" was excerpted from the "Records of Music", and Sima Biao's "Records of the Later Han Dynasty" did not have a complete continuation.
