《资治通鉴·隋纪·隋纪一》
于是牛弘上奏说： 中国的传统音乐多保存在江南地区，以前攻占荆州时得到了梁朝音乐，如今平定蒋州又得到了陈的音乐，这些音乐是历代相传下来的，被认为是符合古乐的，请令人加以修订以作为郊庙朝会演奏的正乐。
牛弘奏： 中国旧音多在江左。前克荆州得梁乐，今平蒋州又得陈乐。史传相承以为合古，请加修缉以备雅乐。
Niu Hong thereupon submitted a memorial stating: Most of China’s traditional music is preserved in the Jiangnan region. On a previous occasion, the music of the Liang Dynasty was obtained after the capture of Jingzhou, and the music of the Chen Dynasty was now obtained after the pacification of Jiangzhou. This music was passed down through the generations and is considered to conform to the music of ancient times. I request that people be ordered to revise and restore it so that it may be played as the official music for suburban temples and imperial courts.
