The large percussion instrument of the Han ethnic group in ancient China, the chime bell, originated in the Zhou Dynasty and flourished during the Spring and Autumn Period and Warring States Period until the Qin and Han Dynasties. China was the earliest country to manufacture and use musical clocks. It is made of bronze and arranged in order of pitch by flat round clocks of different sizes. It is hung on a huge clock stand and struck with T-shaped wooden hammers and long rods, which can produce different musical sounds. Because each clock has a different pitch, striking according to the music spectrum can play beautiful music. Hang a set of copper bells with different tones on a wooden frame, and have the maid strike and play music with a small wooden mallet.
