Research of Gyuen kiok and Kon kiok

由于我们必须使用Do、Re、Sol和La中的叉指惯例，所以Kon歌剧的音调根据Mi音进行划分。宋代的阿修和大编恩吉林都有关于这一密音的记载。唐代的二十八把钥匙也是根据米氏挑选的。我们可以知道，康剧的钥匙起源于唐代。

Kon opera's tones are divided according to Mi sound, because We must use the fork-fingering conventions in Do, Re, Sol, and La. There were some records of this Mi sound in Ngak sho and Tai bieng ngio lam of Song dynasty. The twenty eight keys of Dang dynasty were also chosen according to Mi. We can know Kon opera's Keys derive from Dang dynasty.
