49. Celestial Air Defining Biyu Mode
- From standard tuning slacken 3rd string: 1 2 3 5 6 1 2 (in Folio I called manjiao2)
神品碧玉意 1
Shenpin Biyu Yi

Although this lowered third string tuning seems rather basic, and the number of names given it (see below) also seems to underline its importance, not many melodies published in Ming dynasty used it.3

(The following explanation is added under the name of the mode:)

"Slacken 3rd string one degree: open 5th string = 3rd string stopped in 10th position.
Another school says tighten 3rd, 5th and 7th each one degree."
(The latter yields 5 6 2 2 4 5 7 = 1 2 5 5 7 1 3 , but this alternative tuning will not work here.)

Shen Qi Mi Pu has three pieces using this tuning:

In each of these pieces the main note is 1 (gong), but whereas in Dunshi Cao the secondary note is 5 (zhi), for the other two melodies the secondary note is 3 (jiao), with 6 (yu) also being quite important.

Xilutang Qintong (1549) groups melodies using the lowered third tuning under three headings:

Fengxuan Xuanpin (1539) calls this tuning manjiao. So does Chongxiu Zhenchuan Qinpu (1585), though its commentary adds that it is also called biyu and wumei.4

Xilutang Qintong uses the name biyu for a different tuning, a quite odd one: from standard tuning lower strings 1, 4, 6, giving the 3rd an 4th strings the same pitch: 4 6 1 1 3 4 6 ( 6 1 3 3 5 6 1)! To further complicate matters, the title of the SQMP melody said to be in biyu mode, Baji You, is later used for a completely different melody in mangong mode (lower 1, 3, 6), and this mangong tuning is also called taicu.

The modern repertoire includes a few melodies in this tuning. In particular, the Mei'an school put three melodies into this tuning: Fenglei Yin (see under 1539), Qiujiang Yebo (see under #24 Yin De) and Saoshou Wentian (see under #45 Huangyun Qiusai).9 It calls this tuning linzhong.10
