Du Kui

Du Kui ( 180–225), courtesy name Gongliang, was a musician and official who served under the warlord Liu Biao in the late Eastern Han dynasty of China. He served in the state of Cao Wei during the Three Kingdoms period.

Life Du Kui attempted to stop Liu Biao from performing imperial music in his own court. He was proficient in tuning the bells and other musical instruments expertise, but not in arrangement of dances and singing. With help from other court specialists, he researched old musical practices and texts and gained credit for "starting restoration of the ancient music" (yayue).

While in the service of the warlord Cao Cao, Du Kui got into an argument with Chai Yu , a bell-caster. He had forced Chai Yu to recast the bell set several times for the lack of regular pitch.

Cao Cao's successor, Cao Pi, favoured Chai Yu. Under the pretext of Du Kui's discomfort with court music for entertainment (mouth organ and zithers), Cao Pi had him dismissed. Du Kui died soon afterwards.

Legacy Liu Xie (465–522) praised Du Kui, along with Fu Xuan (217-278) and Zhang Hua (232–300), for "correcting Caos' mistakes" (wenxin diaolong). A Song dynasty treatise by Zhu Changwen mentioned that Du Kui had a son, Du Meng . The information is nowhere corroborated.

Du Kui's apprentice, Chen Qi (陳頎; or Chen Hang 陳頏), was a mentor to Xun Xu (died 289), the leading court musician under Emperor Wu of the Jin dynasty.
