Lülü chanwei 律呂闡微

Oct 7, 2013 © Ulrich Theobald

Lülü chanwei 律呂闡微 "Details on the pitchpipes" is a book on music compiled during the Qing period 清 (1644-1911) by Jiang Yong 江永 (1681-1762), who also wrote the book Lülü xinlun 律呂新論, and several comments to various Confucian Classics.

The 10-juan long book begins with a discussion on music by the Kangxi Emperor 康熙帝 (r. 1662-1722), Huangyan dingsheng 皇言定聲. In the book itself he largely follows the earlier musical theory of Zhu Zaiyu 朱載堉 (1536-c. 1610) from the Ming period 明 (1368-1644) (see Yuelü quanshu 樂律全書), but does not operate with trigonometric calculations, as Zhu did for the exact determination of the tones of the musical scale. Yet he makes some remarks to Zhu's book and so constitutes its first commentary, and is furthermore able to calculate the Jiazhong Pipe 夾鐘 from the Ruibin Pipe 蕤賓 which had been impossible for Zhu Zaiyu.

The Lülü chanwei is included in the series Siku quanshu 四庫全書.
