Bianzhong
Ancient Chinese bronze chime bells used in ritual and court music.
Bianzhong (Chinese: 編鐘; pinyin: biānzhōng) are ancient Chinese musical instruments made from a set of bronze bells that are played to produce melodies. China was the first nation to create and use musical chimes, which are also referred to as chime bells. These bell sets functioned as polyphonic instruments, with some examples dating back between 2,000 and 3,600 years. The bells were suspended from a wooden frame and struck with a mallet. A wooden hammer and rod could be used to hit the bronze bells, generating different pitches. Alongside stone chimes known as bianqing, bianzhong played a key role in China’s ritual and court music from ancient times onward.
Several sets of bianzhong were brought to the Korean court during the Song dynasty. In Korean, the instrument is called pyeonjong, and it became a vital part of Korea’s ritual and court music, where it remains in use today. In Vietnam, the instrument—used in ceremonies at the court in Huế—is known as biên chung. Its Japanese name is henshō.
**History**
Although the oldest clapperless bells in China date back to around 2100 BCE, the arrangement of zhong bells into bianzhong (literally “arranged zhong”) emerged during the Zhou dynasty (1046–256 BCE). Bianzhong from this era contained between 13 and 64 individual zhong, each capable of producing two distinct pitches, and were suspended either obliquely or vertically. In ancient China, the chime was a special instrument reserved for the upper class and served as a symbol of power and wealth. In one Zhou-dynasty set, the largest bell measured 153.4 centimeters (60.4 inches) in height and weighed 203.6 kilograms (449 pounds), while the smallest stood 20.4 centimeters (8.0 inches) tall and weighed 2.4 kilograms (5.3 pounds).
The instrument’s design changed significantly during the Qin and Tang dynasties (221 BCE – 907 CE). Bianzhong shrank in size during this period, limited to sets of 14, 16, or 24 bells. Because of differences in bell construction, each zhong produced only one pitch. These bianzhong were tuned either to a seven-note scale or in twelve semitones.
By the end of the Song dynasty (960–1279 CE), musicians had standardized bianzhong construction and ritual performance. Typical instruments from this period consisted of 16 bells suspended vertically in a two-tiered frame. This design remained standard through the Qing dynasty (1644–1911 CE) and

Lore & Background
While the oldest clapperless bells in China date to as early as 2100 BCE, the organization of zhong bells into bianzhong developed in the Zhou dynasty (1046–256 BCE). Bianzhong from this era had varied numbers of individual zhong (between 13 and 64), each of which could produce two distinct pitches and were suspended obliquely or vertically. In ancient China, the chime was a special instrument for upper-class people and a symbol of power and wealth. The instrument's construction shifted dramatically in the Qin and Tang dynasties (221 BC – 907 CE), decreasing in size and limited to sets of 14, 16, and 24 bells, each producing only one pitch. Musicians standardized bianzhong construction and ritual performance by the end of the Song dynasty (960–1279 CE), with typical instruments consisting of 16 bells suspended vertically in a two-tiered frame. Through the Qing dynasty (1644–1911 CE) into the modern day, this construction remained standard.
Reader's Guide
Bianzhong holds a significant place in East Asian musical history. As a polyphonic instrument, it was central to China's ritual and court music from ancient times. Its influence spread to Korea, where it is called pyeonjong and remains in use for Confucian ritual celebrations, leading the orchestra and punctuating hymn phrases. In Vietnam, it was used in court ceremonies at Huế and is called biên chung. The instrument's unique construction—with a lens-shaped cross-section and concave mouth—allows each bell to produce two different musical tones depending on where it is struck, a feature that distinguishes zhong from all other types of cast bells. The rediscovery of Zhou-dynasty bianzhong by archaeologists in 1978, particularly the complete ceremonial set of 65 bells from the tomb of Marquis Yi (c. 430 BCE), sparked a revitalization of performance and construction of that form. This set, still playable after almost 2,500 years, covers a range of five octaves and is fully chromatic in the central three octaves. The bianzhong of Marquis Yi is now displayed at the Hubei Provincial Museum and has been performed on three times since excavation, most recently for the Hong Kong Reunification ceremony in 1997.
Did You Know?
- Each bianzhong bell can produce two different musical tones depending on where it is struck: the center gives the primary tone, while the left or right corners give a secondary pitch a major or minor third higher.
- The largest bell in one Zhou-dynasty set was 153.4 centimeters tall and weighed 203.6 kilograms, while the smallest was 20.4 centimeters tall and weighed 2.4 kilograms.
- A complete ceremonial set of 65 zhong bells was found in near-perfect preservation in the tomb of Marquis Yi, who died around 430 BCE.
- In 1992, the 3,000-year-old Jin Hou Su bianzhong was purchased from the Hong Kong antique market after being looted from tombs of the State of Jin and smuggled out of China.
Frequently Asked Questions
What exactly is Bianzhong?
Bianzhong is a set of bronze bells that function as a polyphonic musical instrument. The bells are hung from a wooden frame and struck with a mallet to produce distinct pitches. They are also widely known as chime bells.
How old is the Bianzhong tradition?
Some surviving examples date back between 2,000 and 3,600 years. The practice of crafting and performing with these bell sets spans from the Zhou dynasty (1046–256 BCE) all the way to the present day.
How is a Bianzhong set actually played?
Each bronze bell is suspended from a wooden frame, and a performer strikes them with a wooden hammer or rod. Hitting different bells yields different pitches, allowing the set to produce full melodies rather than a single tone.
What made China's Bianzhong unique in the ancient world?
China was the first civilization to develop and use structured musical chimes as an instrument. Their polyphonic design—capable of producing multiple simultaneous notes—set them apart from simpler single-note percussion of the era.
What role did Bianzhong play in ancient Chinese society?
These bronze chime bells were central to ritual ceremonies and court music, especially during the Zhou dynasty. They were frequently paired with stone chimes called bianqing as part of a broader ceremonial musical tradition.
