Ten Degrees of One Tone: Zheng, Shao, Zhong, Kai, Pan, Zhi, Yu, Jia, Tai, Shang

The Mirror Classic of Bian Que next introduces one of its most important coding systems:

The high and low of tone are Zheng, Shao, Zhong, Kai, Pan, Zhi, Yu, Jia, Tai, and Shang. One tone has ten divisions; these are differences in qi and distinctions in voice.

In other words, there is not only one Gong or one Jue. Each basic tone is further divided into ten levels.

The Five Tones are not five points, but five scales

The text directly gives examples:

Zheng-Gong, Shao-Gong, Zhong-Gong, Kai-Gong, Pan-Gong, Zhi-Gong, Yu-Gong, Jia-Gong, Tai-Gong, Shang-Gong. Jue, Zhi, Shang, and Yu follow the same method.

The important shift is from “category” to “category × degree.”

With only the Five Tones, there are five broad classes. Adding ten degrees allows much finer high-low distinctions within each class.

This is a common requirement of quantitative systems: first create coarse classes, then establish finer scales within each class.

How are the ten degrees generated?

Again, the text does not merely list names but describes multiplicative relationships:

Zheng multiplied by Zheng gives Shao; Shao multiplied by Zheng gives Zhong; Shao multiplied by Shao gives Kai; Shao multiplied by Zhong gives Pan…

The sequence continues through Zhi, Yu, Jia, Tai, and Shang.

The exact numerical values underlying these operations still require reconstruction, but the ten names clearly intend to mark ordered proportional degrees, not simply adjectives.

Do not rush to translate the ten names into emotions or personality traits

Words such as “Shao” and “Tai” invite intuitions of less and greater, while “Kai” and “Pan” may invite semantic associations. But in this chapter the safest reading is to treat them first as scale labels.

The text itself defines them as the “high and low of tone” and as “ten divisions of one tone.” Later they combine with different Five Tones into codes such as Shao-Jue, Tai-Yu, and Pan-Gong.

Assigning each word a fixed organ or pathomechanism too early would destroy the text’s mathematical hierarchy.

Why is this resolution necessary?

The author’s aim is not simply to tell Wood from Metal, but to infer prosperity and decline, excess and deficiency, and left-right shifts in channel qi transformation from tone and lü.

Five broad categories are too coarse for such distinctions. The ten degrees create a finer state space.

The second series now has two coding layers:

Layer 1: Yong / Gong / Shang / Jue / Zhi / Yu / Su.

Layer 2: Zheng / Shao / Zhong / Kai / Pan / Zhi / Yu / Jia / Tai / Shang.

The next article asks whether these “high-low” degrees refer only to audible pitch or to a broader qi-transformational state.
