This bronze bell is known as a bo. It is decorated with dragons swallowing geese and has a handle in the shape of two dragons. It required great skill to make a bo and bells of similar size were not made in the west until a thousand years later. This bo would have been part of a set of bells of different sizes each playing different notes. It is played with a hammer and plays two different notes depending on where it is struck.
How was harmony created through music in ancient China?
This bell was made at the beginning of the Warring States period - a time of political fragmentation and moral crisis in China. It was in this turmoil that the Chinese political philosopher Confucius developed his philosophy. Confucius had one overwhelming message: if we are to achieve a state of orderliness and peace, we need to return to traditional values of virtue. Confucius was also a keen musician and saw in music the harmony he wanted to achieve in society.
A set of bronze bells like this one was played during the ceremony to pass Hong Kong from British to Chinese rule
Playing an important role in China
Bells were used in ancient Chinese rituals to communicate with ancestral spirits, to sound the retreat in battles and also for entertainment as ensemble instruments in concert with other instruments, singers and dancers.
Ancient Chinese bells are not circular but have rather an almond-shaped cross-section. This is important because it means the sound dies away quickly and does not interfere with any following music. It gives a well-focused pitch and is rather more musical than the sound of a circular bell.
Chinese bells have no clappers, so they make their sounds by being struck with wooden sticks. Their shape gives them two distinct pitches, depending on whereabouts on them they are struck.
In southern China, in Hunan and Jiangxi provinces, very large bells have been excavated (dating to the Zhou dynasty, about 1050-221 BC), which are heavier than tuned bells and seemed to have been played as a single unit. The tones are more striking and lack the harmonies of the tuned bells which indicate that they were used as untuned, ritual instruments, rather than to create melodies.
The most famous Chinese bell set in the world was found in the tomb of the Marquis of Yi from one of the warring states of China (475-221 BC) called Zeng. The Marquis obviously loved music and was buried with many musical instruments including zithers (a stringed instrument), drums, flutes, pan pipes and chimes. To play the instruments for him, 22 servants were killed to accompany the Marquis to the afterlife.
The bell set consists of 65 tuned bells and covers a range of five octaves. They weigh a total of around 4,521kg and are inscribed with over 3,700 Chinese characters telling us (amongst other things) the two tones each bell can play.
The bells can still be played and were used by the contemporary composer Tan Dun when he was asked to compose music to commemorate the transfer of Hong Kong to China in 1997.
Even today, most Buddhist and Daoist temples are furnished with bells which are beaten as part of the religious ceremonies.
