A brief background on the law of fifth-degree intergeneration

The law of fifth-degree intergeneration is much earlier than Zhu Zaiyu. Zhu Zaiyu’s greatest contribution was the twelve-mean law and nozzle correction value. Pure fifths have long been used in the law of intergenerational fifths. In the era of the law of fifths, the perfect fifth was slightly wider than the fifth in the law of equals. Both were called linear fifths, but they were not equal.

The law of mutual generation of fifths is the earliest temperament system recorded in ancient China. It is derived from the "three-point profit and loss method", that is, under the same tension, three thirds of a fixed-length string are cut off. One, you get the perfect fifth above the original length of the string.

The record of the law of mutual generation of five degrees first appeared in the Spring and Autumn Period of the Pre-Qin Dynasty and the Warring States Period. The book recording this law system is said to be "Guanzi·Diyuanpian" written by Guan Zhong in the Warring States Period. However, it is pointed out that it is not equivalent to Guanzi. The invention may be attributed to Guan Zhong in later generations; it may just be Guan Zhong's record of the method of producing laws at that time, and it may not necessarily be his creation. Therefore, the discovery of the pure fifth degree seems impossible when it comes to people and historical data.
