Bianzhong is an ancient Chinese heavy musical instrument with a long history. It was not only used for Heaven and Earth worshiping, guests entertaining, ancestors esteeming, peace praying and blessing, but also used for people education and music teaching. Ancient rulers would smelt and cast bells or tripods to declare the majesty and peace every time there are grand or major celebrations, hence, chime bells are also called Peace Bell and only princes and marquises can have a privilege to enjoy the joy of chime bell beating. The exquisite chime bell represents the highest technical level of the Bronze Age and manifests with its fossilized history and millennium constant timbre the splendid civilization that the Chinese nation was far ahead of the world thousands of years ago, thus it is called as a “rare treasure” and a “wonder of the world” by the experts and scholars at home and abroad. The chime bell’s scale is equal to the heptachord in modern C Major, an international standard pitch.
