Which five tones does the five tones refer to?

The five tones refer to the five tones of Jiao, Zheng, Gong, Shang and Yu in the Chinese pentatonic scale.

The intervals between two adjacent tones in the five tones are all major second degrees, except that between Jiao and Zheng, and between Yu and Gong (the palace an octave higher), which is a minor third.

It belongs to the Five Elements in ancient China.

There is another ancient work "Five Tones", which is an article recorded in the ancient military work "Six Tao", recorded in the "Long Tao Chapter" - On Military Organization.

This article introduces the method of using the five tones and the five elements to observe and judge the enemy's situation.

Judging the enemy's situation and even commanding the use of troops based on the matching of the five tones and the five elements is almost absurd and cannot be trusted.

However, his idea of ??using various means to detect the enemy's situation, judging the enemy's situation through various clues, and then making corresponding decisions still has merit.

The Qing Dynasty general Nian Gengyao alerted the police when he heard the wild geese. This is an example of this.
