The five tones of "Shang Shā, Jiao Ju 'e, Zheng zhǐ and Yu Wusheng" in "Ling Xie Shu Ke" are matched with the five internal organs: the spleen should be active and the voice should be slow; The lung should be business, and its sound should be clear; The liver should respond to the angle and have a long voice; The heart is giving, and the voice is bright; Kidney should be feathered, and its sound is heavy and thin, which is the correct pronunciation of the five internal organs. According to legend, it was named after the five tones of China's earliest musical instrument "Fu".

In traditional Chinese medicine, the five tones belong to the five elements, and the five internal organs can influence the five tones, and the five tones can adjust the five internal organs. Feather-raising in the upper horn of the palace and five-tone harmony and collocation have different effects on people's health. In ancient times, really good Chinese medicine used music instead of acupuncture or Chinese medicine.

Gong, Shang, Jiao, Zheng and Yu, which originated in the Spring and Autumn Period, are the five basic scales of ancient music in China, which are equivalent to Do (Gong), re (Shang), Mi (Jiao), Sol (Zheng) and La (Yu) of western music, also known as "Can't".
