Jia Hu bone flute is the earliest playing instrument discovered in China. The excavation of Jia Hu bone flute is an important event in the field of Chinese music archaeology, and it is also the most direct and powerful evidence that Chinese music culture has a history of 9,000 years of civilization. From the unearthed artifacts, its shape is extremely fixed, its production is very standardized, its essence is good, and its expression is extremely strong. Most musical ranges can reach more than two octaves.

Jia Hu bone flute is the oldest musical instrument discovered in China archaeology so far, and it is also the earliest musical instrument that can be played in the world. Bone flute is made of crane ulna tube. Fine grinding, 7 holes. There is a small hole between the sixth hole and the seventh hole, which can emit two sounds after sound measurement. It should be a tuning hole drilled to adjust the pronunciation of the seventh hole. It is worth noting that two bone flutes with similar shapes were unearthed in this tomb. According to the sound measurement research, they are a woman and a man, which confirms the tradition of flute for men and women in China since ancient times. This kind of flute has been proved to be a vertical bone flute and the ancestor of clarinet or flute instrument in later generations. At that time, people used this kind of flute to play rhythmic notes to express their understanding of life and reverence for gods; Modern musicians can still play the five-step Chinese Cabbage with this flute. Crane ulna system, mostly seven holes, can be tested by vertical blowing method, which can play six-tone music. The bone flute in this site is the earliest musical instrument found in the world, and it can still be played today, reflecting the highly developed prehistoric music civilization in China. After exploration, the sound of ancient music with bright and simple timbre and original style has "scattered" into the eardrum of modern people from Jia Hu bone flute. "It has two octaves and a complete chromatic range. This means that Jia Hu Bone Flute can not only play the traditional five-tone or seven-tone in the Central Plains, but also play the music of various voices of ethnic minorities or foreign countries. " Li Hong said: "This practice has made us clear the significance of Jia Hu bone flute in music culture. Jia Hu Bone Flute has had seven scales or even variable scales, while other melodic instruments in the same period are within the range of three tones, so the appearance of seven scales will undoubtedly take a long historical process. And our practice has strongly impacted the once recognized view that traditional music is dominated by five tones, and also impressed us with the incredible creativity of prehistoric ancestors! "
