Guqin originally had only five strings. Later, King Wen went to prison and missed his son Bo Yikao, adding a string to Wen. When the week was cut, a string was added for Wu Xian. Collectively known as the Wu Wen lyre.
The piano face consists of seven thick and thin strings from outside to inside. In ancient times, strings were made of silk, but now they are mostly made of steel. If there are not many turns of the string around the goose's feet, other solid metal wires should be used to increase the stability of the string.
The lyre unearthed from Mawangdui No.3 Han Tomb has simple structure, small horn, low resonance sound, solid wood at the end and no emblem on the panel. Cai Yong's "Cao Qin" is the richest and most detailed book focusing on pre-Qin music. The original book has been lost, and it has been compiled by later generations. There are also five Qin Ge, which are collectively called "Cai Wunong".

A sign with thirteen points embedded outside a line is called the emblem. Emblems are mostly made of mother-of-pearl, and elegant emblems are also made of gold, silver, jade, stone and other materials. The point of the emblem is actually the overtone vibration node of the string, which is naturally formed and has a pure melody.
3. Piano head
The upper part of the piano head is called the forehead, and the lower part of the forehead is inlaid with hardwood for threading, called Yueshan, also known as Lin Yue, which is the highest part of the piano. On the right side of the piano face, it is hardwood embedded horizontally at the head of the piano from 8 to 10 cm.
4. The end of the piano
From the waist down, it is called "the end of the piano". The end of the piano is inlaid with a kind of hardwood "Dragon Gum" with shallow grooves, which is used for threading. The decorations on both sides of the dragon glue are called "crown angle", also known as "focal tail". There is also a dark groove at the end of the piano, which is called "rhyme marsh".
