Few instruments carry their own century-thick atmosphere into the room before the first note is struck. The Guzheng — the Chinese zither — is one of them. Long before it became a familiar sound in Chinese television dramas and contemporary film scores, it was already being played in royal courts, scholar’s studies, and village ensembles across China for more than two thousand years.

This article traces the historical journey of the Guzheng — from its earliest written mention in The Records of the Grand Historian, through the dynastic periods that quietly reshaped it, to the 21-string instrument played around the world today. It draws on Ms Jin Loh’s own studies of the instrument with Chinese music conservatory professors and associate professors holding doctoral degrees in Guzheng performance.

The Earliest Written Record — The Shiji

The Guzheng’s documented history reaches back more than two thousand years. One of its earliest surviving written references appears in the Records of the Grand Historian — the Shiji (史记) — a foundational work of Chinese historiography compiled by the Han Dynasty historian Sima Qian around 100 BC. The Shiji is one of the most authoritative sources on early Chinese culture, and its mention of the zheng tells us that the instrument was already part of recognisable musical life by then.

According to historical research, the earliest form of the zheng (筝) was a far simpler instrument than today’s. It carried only five strings, and its body was constructed of bamboo — a far cry from the long, curved hardwood resonating body of the modern Guzheng. The instrument we now know is the result of two millennia of patient evolution.

Historical Names — Han Zheng & Qin Zheng

The Guzheng has been known by several names through history, each of which reflects the cultural soil it grew from. It has been historically referred to as the Han Zheng (汉筝) and the Qin Zheng (秦筝) — names that locate the instrument firmly within the Han Chinese musical tradition and its early geographical roots.

Today, the prefix “gu” (古) — meaning “ancient” — is added to distinguish the instrument from its more contemporary descendants and to honour the depth of its heritage. The full name — Gu Zheng (古筝) — literally translates as “ancient zither.”

Through the Dynasties — The Tang Era and Beyond

As the centuries unfolded, the zheng evolved both in its physical form and in its musical role. By the Tang Dynasty (around the 7th century AD) — one of the great cultural high-points of Chinese civilisation — the zheng had become widely embedded in both court music and folk music. It was no longer the simple bamboo instrument of antiquity; more strings had been added, and its expressive range had grown considerably.

Through the Tang and the dynasties that followed, the zheng gradually expanded into the twelve-string form, and later still into the thirteen-string form. Each addition allowed the instrument to express a richer range of melody, ornamentation, and emotional colour — suiting the increasingly refined musical tastes of the eras that played it.

The 13-String Zheng — A Standard Form Emerges

By the early 20th century, the 13-string zheng had become widely recognised as a standard form of the instrument. Throughout this long period — and indeed long before — the zheng was used in a remarkable variety of musical settings.

It appeared as a solo instrument, where its full expressive voice could be heard most clearly. It was equally at home as part of traditional Chinese ensembles, weaving its lines into the larger fabric of Chinese instrumental music. And in some traditional performance practices, the zheng was used as a self-accompaniment for singing — the singer played the strings while accompanying their own voice. These diverse historical uses are recorded across centuries of Chinese literature, and they reflect the rich artistic life the instrument has led across very different eras.

The Modern 21-String Guzheng

Although the Guzheng is rooted in deep history, it is also very much a living modern instrument. Today, the most widely-played standard form is the 21-string Guzheng. The expansion from 13 to 21 strings, completed in the twentieth century, dramatically widened the instrument’s expressive range — allowing for richer harmonic textures, broader melodic reach, and more sophisticated repertoire.

The modern Guzheng is typically tuned to a pentatonic system (a five-note scale within each octave), and the 21 strings span approximately four octaves. This generous range — combined with the left-hand techniques of pitch bending, vibrato, and ornamentation — has kept the Guzheng remarkably relevant in both traditional Chinese music and the contemporary musical worlds of pop, drama soundtracks, and film scoring.

Regional Performance Traditions

One of the quiet beauties of Guzheng music is that it does not speak with a single voice. Across the geography of China, several distinct regional performance traditions developed over the centuries, each with its own characteristic phrasing, ornamentation, and tonal colour. Among the most respected and recognised are:

• Hakka Guzheng style — 客家筝
• Chaozhou Guzheng style — 潮州筝
• Shandong Guzheng style — 山东筝
• Henan Guzheng style — 河南筝

Each of these traditions reflects the musical character and cultural soil of its own region. To a sensitive listener, a Hakka piece does not sound the same as a Chaozhou piece, even when both are played on the same instrument; the inflections, the phrasing, the way the left hand bends a note — all carry the fingerprint of place. To learn the Guzheng deeply is, in time, to learn to recognise these voices and play within them with sensitivity.

The Guzheng in the World Today

The Guzheng remains one of the most popular traditional instruments in China, with a playing population numbering well into the millions. In recent years — through cultural exchange, online learning, and the global rise of Chinese drama and film — the Guzheng has also begun to attract a steadily growing audience and learner base around the world. Students from the United Kingdom, the United States, Australia, Canada, Singapore, Thailand, Japan, and many other countries are now picking up the instrument for the first time.

And so an instrument that was first written into history more than two thousand years ago, with five strings of bamboo, continues to find new hands to play it — carrying the beauty of Chinese musical heritage, gently and with grace, into the present day.
