Guzheng

The guzheng is a traditional Chinese plucked zither. It is an instrument known for its light timbre and strong expressive power.

Musicians value the guzheng for its broad musical range and rich performance skills. It is deeply loved by many Chinese people throughout history. The instrument has served as an ancestor to several other Asian zithers. These include the Japanese koto and the Korean gayageum. It is also related to the Mongolian yatga and the Vietnamese đàn tranh.

To understand how a guzheng works, one must look at its construction. The instrument features a large, resonant soundboard made from Paulownia wood. The strings are arranged from the inside to the outside, numbered 1 to 21 in common models. Most modern guzhengs use 21, 25, or 26 strings. These strings are often made of steel coated in nylon. This specific material was introduced in the 1970s to increase volume while maintaining an acceptable timbre.

High-pitched strings sit close to the player, while low-pitched strings are on the opposite side.

Playing the guzheng involves specific physical techniques and specialized tools. Most modern players wear plectra, or fingerpicks, on up to four fingers of each hand. These picks can be made of plastic, resin, tortoiseshell, or ivory.

In traditional styles, the right hand plucks the notes. The left hand adds ornamentation by pressing strings to the left of the movable bridges. This creates pitch slides and vibrato. One iconic sound is the tremolo, where the right thumb rotates rapidly around a single note. Another technique is Fanyin, or harmonics, where a player taps a string while plucking it to produce a higher octave.

The history of the guzheng spans over two millennia. The oldest discovered specimen held 13 strings and dates to the Warring States period, roughly 475 to 221 BCE.

The instrument became prominent during the Qin dynasty. By the Tang Dynasty, it was perhaps the most common instrument played in China. There are several legends regarding its origin. One account attributes its invention to the Qin general Meng Tian. Another legend describes a 25-string se breaking into two parts of 12 and 13 strings. Over time, string materials changed from silk to brass wires during the Qing dynasty, and finally to modern nylon-coated steel.

Regional styles in China create distinct musical identities. Northern styles include schools from Shandong and Henan. Henan songs are described as fiery, using frequent left-hand slides and thumb tremolos. Shandong songs are described as glamorous and refreshing, with melodic lines that rise and fall dramatically.

Southern styles include Chaozhou, Hakka, and Zhejiang schools. Chaozhou songs often use irregular beats and alternate between hard and soft taps. Hakka melodies are similar to Chaozhou but are less highly embellished. The Zhejiang school uses techniques similar to the pipa, a different Chinese instrument.

Modern guzheng music has expanded significantly since the 1950s. A new modern school has emerged by mixing elements from northern and southern styles. Some pieces even use newer techniques like playing harmony and counterpoint with the left hand. Since the 1980s, composers have even written experimental, atonal pieces. These works do not follow the traditional pentatonic scale.

For example, the song "Ming Mountain" is a contemporary piece that departs from traditional scales. The instrument continues to evolve through collaborations between traditional players and electronic musicians.

The guzheng connects to many different global fields today. It has been used in rock music by artists like the virtual band Gorillaz. It also appears in popular culture, such as in the film Kung Fu Hustle. In literature, the name "Guzheng" is used as a code name in the Remembrance of Earth's Past trilogy. The instrument's influence reaches far beyond China, as non-Chinese composers write works for it. This shows how a traditional instrument can remain relevant in a changing, modern world.
