180–225[1]), courtesy name Gongliang, was a musician and official who served under the warlord Liu Biao in the late Eastern Han dynasty of China.
Du Kui attempted to stop Liu Biao from performing imperial music in his own court.
He had forced Chai Yu to recast the bell set several times for the lack of regular pitch.
Under the pretext of Du Kui's discomfort with court music for entertainment (mouth organ and zithers), Cao Pi had him dismissed.
[3] Liu Xie (465–522) praised Du Kui, along with Fu Xuan (217-278) and Zhang Hua (232–300), for "correcting Caos' mistakes" (wenxin diaolong).
