The record of guqin was first found in the Book of Songs, Shangshu and other documents. "Shangshu" contains: "Shun plays banjo, sings poems in the south, and governs the world." It can be seen that the piano was originally five-stringed, and by the Zhou Dynasty it had seven strings. Ying Shao's "Custom Pass" in the Eastern Han Dynasty: "Seven-stringed man, seven-stringed man, big string is the monarch, small string is the minister, and Wen Wang and Wu Wang add two strings to combine the grace of the monarch and the minister." During the Three Kingdoms period, the pattern of seven strings and thirteen emblems of guqin was basically stable and has been passed down to this day.
The playing forms of guqin are mainly piano music and solo. According to literature records, in the pre-Qin period, guqin was mainly popular among the gentry and above, and became folk music after Qin Dynasty except for sacrificial ceremonies, court meetings and suburban temple ceremonies. As for the piano as a form of vocal accompaniment, there was a record of "playing the piano with the instrument" as early as in Shangshu. The Zhou Dynasty often sang with the accompaniment of harps and harps, which is called' string songs', that is, the so-called piano songs since the Tang and Song Dynasties. There are five poems in Cai Yong's Cao Qin in Han Dynasty, namely Zhou Zhi's Xian Ge, among which Twelve Caos, Nine Quotations and Hejian Zage are all sung with the help of Qin.
During the Spring and Autumn Period and the Warring States Period, Guqin solo music had certain artistic expression ability, such as the legend that Boya was good at playing the piano in his childhood. At that time, famous violinists included Shi Juan of Wei, Shi Kuang of Jin, Shi Wen of Zheng and Shi Bao of Lu. Famous Qin music such as Mountain, Running Water, Luo Chaofei, Yangchun and Snow White have been recorded in the history books.
