When these two tones are positive drum sounds, the side drum tones become the major third degree of change palace and change sign. Thus, the positive drum tones of the whole group of chimes form a complete pentatonic scale, and the entire tone sequence can form a six-tone or seven-tone scale. For example, a set of button bells unearthed from Tomb No. 1 (Chunqiu Chu Tomb) in Xichuan, Henan During this period, the bells produced two tones each, and the bird patterns were generally not cast on the side drums.
In the Warring States Period, in addition to the nine bells, there were thirteen and fourteen bells.

The discovery of this chime has largely made up for the lack and inadequacy of literature records, and has important historical and scientific value. It vividly shows the splendid achievements made by the music culture and bronze casting process in the Spring and Autumn Period and the Warring States Period of our country. It is a treasure of the Chinese nation, and it is an unprecedented major discovery in the history of archaeology and music in my country and the world.

From the Warring States Period to the Western Han Dynasty, in the ruins of southwestern China, such as Yunnan, Guangxi, Guangdong, Sichuan and other places, various double-horned button-shaped bells and barrel-shaped bells with unique local characteristics were found. They are musical instruments used by ethnic minorities in the southwest.
During the Qin and Han Dynasties, the ritual and music system since the Zhou Dynasty completely collapsed, the prosperity of the pre-Qin Zhongpan music also ended, and the production of two-tone chimes disappeared.
According to historical records, Qin Shihuang cast the pillars of the bell stand in Xianyang, "Zhong Yu Jinren Twelve", and also built the "Bell of Thousand Stones" and "Zi of Ten Thousand Stones". Such a huge bell should refer to the morning bell. It is a symbol of imperial power and monarchy in all dynasties. With the rise of Buddhism and Taoism, after the Eastern Han Dynasty, Buddhist bells (also known as Brahma bells) and Dao bells were used in temples and Taoist temples. The earliest extant Buddhist bell was cast in the seventh year of Chen Taijian (575) during the Southern and Northern Dynasties, and it is now at the place of Gentaro Inoue, Tokyo, Japan. After the Tang Dynasty, giant Buddhas and Dao bells were often cast by emperors, such as the "Jingyun Bell" in Jinglong Temple in Chang'an City (now Xi'an) in Tang Dynasty, the "Yongle Bell" in Beijing's Dazhong Temple, and the "Yongle Bell" cast in Yongle (1403-1424) of Ming Dynasty. big clock". Their practical use is to tell the time. The Yongle Bell is 6.94 meters high and has a diameter of 3.3 meters. It weighs 46.5 tons.

Inside and outside the clock, there are seventeen types of Buddhist scriptures cast in neat regular script, totaling more than 227,000 characters. This bell is well-known both at home and abroad for its loud sound, superb casting technology and calligraphy art, and has the reputation of the ancient "bell king".
In order to restore the ancient system of Zhou Li, the emperors of the Qin and Han dynasties also cast the bells and mushrooms used in Yale. For example, during the Southern and Northern Dynasties, Emperor Wudi of Nanliang used twenty-six bells and five hundred and four pieces, all of which were prepared with twelve laws. In the Song Dynasty, the retro style was especially prosperous. During the reign of Emperor Huizong of the Song Dynasty (1101-1125), he set up the "Dasheng House", an institution in charge of music, and cast twelve sets of chimes, about 300 pieces. So far, there are still some that have been recorded and circulated in the world. There are more than ten pieces, the shape of which is imitated from the Song Gongxu bell of the Song Dynasty in the Spring and Autumn Period unearthed in Yingtianfu (now Shangqiu, Henan) at that time. This device is called a bell, but it is actually a mushroom. The existing Dasheng Ruibin Bell in the Palace Museum has a height of 28 cm, a double-dragon-shaped complex button, a flat mouth, and the zheng, seal, and drum parts are decorated with pan-patterns.

The chimes used in the Qing court were a set of sixteen pieces. Suspended on two tiers of bell racks, eight pieces on each tier. From Beiyi Ze to Ying Zhong, there are twelve laws plus four times laws.
