The Chinese sound law mainly uses the five-tone scale, i.e., Gong, Shang, Horn, Zheng and Feather; and the twelve rhythms, i.e., Huang Zhong, Da Lu, Tai Tu, Jie Zhong, Gushu, Zhong Lu, Lei Bin, Lin Zhong, Yizhe, Nan Lu, Wu Shao and Ying Zhong. The twelve tunes are also known as the twelve tunes or ryue. Ancient Chinese pentatonic scale: Gong, Shang, Jiao, Zheng Yu, which is equivalent to the modern musical scale of C, D, E, G, A. China was the first country to adopt the "five-tone scale". China was the first country to adopt the "three-part gain and loss method" to calculate the meter. The ancient Chinese pentatonic scale is in line with the calculation of Pythagoras in ancient Greece, and is also close to the modern scientific calculation of the scale, which has a certain degree of scientificity. The spirit of the Zhouyi runs through the creation and calculation of the pentatonic scale and the ryoru, as well as their interrelationships, which serve as their theoretical basis. In other words, the ancient doctrine of sound and rhythm was again established on the basis of the Yin-Yang and Five Elements theory of the Zhouyi. In the Han Book of Rituals and Calendars, it links the Gong, Shang, Jiao, Zheng and Fei with the earth, gold, wood, fire and water, east, south, west, north and center, spring, summer, autumn and winter, and it is said that the Gong is the sound of the earth, which resides in the center, and corresponds to the four directions and the four times of the year; the Jiao is the sound of wood, which resides in the east, and is in the spring; the Hui is the sound of fire, which resides in the south, and is in the summer; the Shang is the sound of gold, which resides in the west, and is in the autumn; and the Fei is the sound of water, which resides in the north, and is in the winter.
