“The metal takes lead among Bayin (eight categories of musical instrument in ancient orchestra: metal, stone, string, bamboo, gourd, clay, leather, and wood).” These kinds of ritual musical instruments, of which the amount and the size manifest the statue of the host, were indispensable during the royal fetes and banquets in the Shang and Zhou Dynasty. These bronze percussion instruments were made produced more and more complicated and numerous, evolving from just bronze bells in Xia Dynasty 3000-year-ago, to bronze cymbals in Shang Dynasty. They became Bo Bells in the Western Zhou. And in the Eastern Zhou they developed into many different kinds of bells.

Serial bells were the court musical instruments of pre-Qin periods, as well symbols of the ancient emperors’ power. Wang Sunhao Serial Bells, with 26 horns, are the largest quantity, biggest size, broadest diapason, made of the most fabulous timbre, all of  which contribute to the mysterious atmosphere, with their penetrating power and the tone sounding boundless glory, of the temples of Chu Emperor 2500 years ago. Wang Sunhao Serial Bells were double tone bells. Both its obverse part and the lateral can make to sound simultaneously producing harmonious notes of a scale in intervals of thirds. Its diapason spans four and a half octaves. This technique had been broadly applied during the Spring and Autumn Period. Prince Zhu Zai put forward the Twelve Laws of the Average. The Wang Sunhao Serial Bells are clear proof of his ideas. They epitomize stateliness, primitive simplicity, resplendence and great atmosphere of the royalty life. On the bells, there is an inscription made up of 133 characters, which says: Wang Sunhao made the serial bells to greet the Chu Emperor. These vassals, honorable guests, father and elder brothers, are to last for ever and ensure our immortality.
