What are the ancient sounds?

China's temperament mainly adopts five tones, namely, palace, business, angle, sign and feather; Twelve methods, namely Huang Zhong, Lu Da, Tai Cong, Jia Zhong, Gu Xi, Zhong Lu, Yan Bin, Lin Zhong, Yi Ze, Nan Lu, Wu She and Ying Zhong. The twelve laws are also called twelve laws or twelve laws. The five tones in ancient China: Gong, Shang, Jiao and Zhengyin, are equivalent to the five scales of modern music: C, D, E, G and A. China first used the "three-point gain and loss method" to calculate the temperament. The pentatonic scale in ancient China is consistent with that calculated by Pythagoras in ancient Greece, close to the scale of modern scientific calculation, and has certain scientificity. The generation, calculation and relationship of five tones and rhythm run through the spirit of Zhouyi and become its theoretical basis. In other words, the ancient temperament theory is based on the theory of Yin-Yang and Five Elements in Zhouyi. Officials, merchants, horns, signs and feathers are connected with earth, gold, wood, fire and water. The so-called east, south, west, north, middle, spring, summer, autumn and winter in the palace are earth sounds, occupying the center and corresponding to the four seasons. The horn is the sound of wood, which lives in the east and the time sequence is spring; The emblem is the sound of fire, living in the south, and the time sequence is summer; It is still the golden sound, living in the west, and the time sequence is autumn; Feather is underwater sound, living in the north, and the time sequence is winter.
