Synopsis

The Guzheng is one of China's oldest plucked string instruments, with a history of over 2,500 years. It became popular in the Qin State during the Warring States period, hence it is also called the Qin Zheng. The modern standard Guzheng has 21 strings and a range of four octaves. "High Mountains and Flowing Water" is its most famous piece, and the story of Bo Ya and Zhong Ziqi, who understood each other through music, has been passed down through the ages. In 2008, the art of Guzheng was included in China's national intangible cultural heritage list. It is one of the most popular traditional Chinese instruments, with over 5 million learners. Its tone is clear, melodious, and evocative, like flowing water or a gentle breeze.

Overview

The guzheng is one of China's oldest and most beautiful plucked string instruments, with a history of over 2,500 years. Its timbre is clear, bright, melodious, and graceful—the high notes are crisp like pearls falling onto a jade plate, the mid-range notes are bright like the tinkling of spring water, and the low notes are deep and resonant like echoes from distant mountains. The guzheng possesses an extremely rich expressive power, capable of conveying both the majestic grandeur of lofty mountains and flowing rivers, and the gentle delicacy of a spring breeze caressing willow branches. It is one of China's most important traditional instruments and a representative symbol of Chinese traditional music culture.

The guzheng was already widely popular in the State of Qin (present-day Shaanxi area) during the Warring States period, hence it is also called the Qin zheng. The earliest guzheng had only five strings. Through thousands of years of development, the number of strings gradually increased, from 12, 13, and 15 strings to the modern standard of 21 strings. In 2008, the art of the guzheng was inscribed on the National List of Intangible Cultural Heritage. Today, the guzheng is one of the most widely learned traditional instruments in China, with over 5 million learners nationwide.

Historical Development

Period	Number of Strings	Development
Warring States	5 strings	Popular in Qin State, called Qin zheng
Han Dynasty	12 strings	Became an important court instrument
Tang Dynasty	13 strings	Spread to Japan via Japanese envoys to Tang (becoming the Koto)
Yuan Dynasty	14-15 strings	Rich development of playing techniques
Qing Dynasty	16 strings	Widely circulated among the populace
1960s	21 strings	Modern standard guzheng finalized
Modern	21-26 strings	Emergence of various improved zheng types

The development history of the guzheng is a microcosm of Chinese music history. From five strings to 21 strings, each increase in string count signified an expansion of range and enhancement of expressive power. The modern 21-string guzheng has a range of four octaves, enabling it to perform music of almost any style.

Guzheng Structure

Component	Material	Function
Soundboard	Paulownia wood	Resonates to produce sound; key to tone quality
Strings	Steel wire wrapped in nylon	Produce sound; 21 strings correspond to different pitches
Bridges (Yanzhu)	Rosewood or red sandalwood	Support strings; movable for pitch adjustment
Body	Rosewood, red sandalwood	Sounding box/resonator; affects timbre
Front & Rear Bridges (Yueshan)	Hardwood	Secure the ends of the strings

The soundboard is the key component determining the guzheng's tone quality. A good guzheng soundboard is made from high-quality paulownia wood—this wood is lightweight, has straight grain, and provides excellent resonance. After careful selection and treatment, the soundboard allows the guzheng to produce a clear and bright timbre. The material of the strings has also evolved—from ancient silk strings to modern steel wire wrapped in nylon, greatly improving both volume and tone color.

Classic Repertoire

Piece	Era	Characteristics
High Mountains and Flowing Water	Pre-Qin	Story of Bo Ya and Zhong Ziqi; most famous guzheng piece
Singing on the Fishing Boat at Dusk	Modern	Depicts fishing boats returning at sunset; most widely known
Battling the Typhoon	Contemporary	Portrays dockworkers battling a typhoon; most technically demanding
Jackdaws Playing in the Water	Guangdong	Representative of Chaozhou zheng music; elegant and refined
Guangling Melody	Ancient Tune	Ji Kang's swan song; heroic and impassioned
Wild Geese Alighting on the Sandbank	Ancient Tune	Desolate autumn scenery; profound artistic conception

"High Mountains and Flowing Water" is China's most famous musical story. During the Spring and Autumn period, when the musician Bo Ya played the qin, he thought of high mountains. The listener Zhong Ziqi said, "How towering! Your will is on the high mountains." When Bo Ya thought of flowing water, Zhong Ziqi said, "How vast! Your will is on the flowing streams." Bo Ya sighed, recognizing Ziqi as his true soulmate—the one who truly understood his music. Later, when Ziqi passed away, Bo Ya was heartbroken. He smashed his instrument and never played again for the rest of his life. This is the origin of the term "zhiyin" (soulmate, literally "knowing the tone")—"seeking a soulmate through high mountains and flowing water" has become a Chinese metaphor for finding a kindred spirit.

Playing Techniques

Technique	Action	Effect
Right-hand Plucking	Thumb, index, and middle finger pluck strings	Produces fundamental tones
Left-hand Pressing	Presses strings to the left of the bridge	Alters pitch, creates expressive nuances (yun)
Tremolo (Yao Zhi)	Rapid back-and-forth plucking with right hand	Produces sustained tones, like a string instrument's long note
Glissando (Gua Zou)	Fingers quickly sweep across multiple strings	Creates a flowing water-like effect
Harmonics (Fan Yin)	Lightly touch specific points on the string	Produces ethereal, clear, and bright tones
Two-hand Coordination	Both hands play different strings simultaneously	Creates polyphonic effects

The most unique aspect of guzheng performance lies in the division of labor and coordination between the two hands. The right hand is responsible for plucking the strings to produce sound, while the left hand presses, slides, kneads, and vibrates the strings to the left of the bridges to alter pitch and timbre. It is precisely the left-hand pressing techniques that give the guzheng its distinctive expressive flavor—those graceful, song-like glissandi and vibratos are the most enchanting aspects of guzheng music.

Cultural Influence

The guzheng holds a lofty position in Chinese culture. Along with the guqin, pipa, and dizi, it is known as one of China's four great traditional instruments. The guzheng is not only widely popular in mainland China but has also spread throughout the East Asian cultural sphere—Japan's Koto, Korea's Gayageum, and Vietnam's Đàn tranh all originated from the Chinese guzheng. In recent years, the guzheng has become increasingly popular internationally—many foreign musicians have begun learning the guzheng, integrating and innovating by fusing it with Western music.
