Detailed Instrument Description

Instrument Name	Ajaeng
Instrument Family	String
Alternative Names	The ajaeng is sometimes referred to as the “bowed zither” due to its bowing technique. In certain regional contexts, it is also called “jeongak ajaeng” or “sanjo ajaeng,” depending on the musical style it is used for.
Geographical Presence	The ajaeng is primarily played in Korea, where it remains a central instrument in traditional music. It is occasionally featured in international performances of East Asian music and world music ensembles.
Instrument Classification	The ajaeng falls under the Hornbostel-Sachs classification system as 311.222, identifying it as a box zither chordophone. This classification includes string instruments with strings stretched over a wooden body that are bowed or plucked.
Unique Features	The ajaeng is characterized by its long, rectangular body, typically made from paulownia wood. It features seven or eight thick silk or nylon strings that are bowed with a resined stick, producing its distinctive raspy sound. The bow is made from a stick of hardened forsythia wood and is rosined to create friction on the strings. The instrument’s construction allows for dynamic changes in tone and expression, with the player adjusting pressure and bowing techniques to create different timbres. The ajaeng is notable for its low, resonant sound that contrasts with the higher-pitched instruments of traditional Korean ensembles.
Sound Characteristics	The ajaeng produces a deep, gravelly, and raspy sound that is highly distinctive in the world of string instruments. Its tone is often described as raw and earthy, with a strong, emotive quality. The instrument’s sound can range from soft, lyrical notes to loud, powerful, and almost percussive tones, depending on how the bow is applied to the strings. Its low pitch and rich, resonant sound make it a key instrument in traditional Korean music, providing both rhythmic foundation and melodic expression. The ajaeng’s characteristic roughness gives it a unique place in Korean music, contrasting with the smoother tones of other string instruments.
Typical Music Genres	The ajaeng is used in traditional Korean music, including court music (jeongak), folk music, and sanjo, a solo instrumental genre. It is also featured in contemporary Korean fusion music, blending traditional Korean sounds with modern styles. The instrument is frequently used to provide melodic and harmonic support in ensemble settings, as well as in solo performances that showcase its dynamic and emotive qualities.
Components	Body, Strings, Bridges, Tuning Pegs, Bow (Rosined Stick)
Construction	The ajaeng is constructed from a long, rectangular wooden body, traditionally made from lightweight paulownia wood. The body serves as a resonator, amplifying the sound produced by the strings. The instrument has seven or eight thick strings, which are made from silk or synthetic materials like nylon. The strings are supported by movable wooden bridges, allowing for tuning adjustments. The bow, made from hardened forsythia wood, is coated with resin to create the necessary friction when drawn across the strings. The strings are tuned using wooden or metal tuning pegs located at one end of the instrument. The ajaeng is unfretted, allowing the player to vary the pitch and tone by adjusting finger pressure on the strings while bowing.
Size and Weight	The ajaeng typically measures about 160 to 180 centimeters (63 to 71 inches) in length and 30 centimeters (12 inches) in width. It weighs around 5 to 6 kilograms (11 to 13 pounds), depending on the materials used and the number of strings.
Variations and Customizations	Variations of the ajaeng include the jeongak ajaeng, which is used for court music and has a larger body and thicker strings, and the sanjo ajaeng, which is smaller and designed for faster, more virtuosic playing. Customizations may involve the type of strings used, with some instruments featuring silk strings for a softer tone and others using nylon or metal for a brighter sound. Decorative elements like lacquer finishes or carvings can also be added to enhance the visual appeal of the instrument. Some modern versions of the ajaeng may have additional strings or adjustable bridges to increase the range of notes and allow for more versatile playing styles.
Instrument History	The ajaeng has its origins in the Goryeo Dynasty (918–1392), where it was introduced from China and became part of Korean court music. Over the centuries, the instrument evolved to suit Korean musical aesthetics, particularly during the Joseon Dynasty (1392–1897), when it became central to both court and folk music. The instrument was traditionally used in jeongak (court music) and has also become a prominent instrument in sanjo, a genre that emphasizes improvisation and virtuosic solo playing. In the 20th century, the instrument was adapted for use in modern Korean music, including fusion and contemporary compositions. Today, the ajaeng continues to play a vital role in Korean music, representing both its ancient heritage and its continued evolution.

Playing Technique	The ajaeng is played with the instrument placed horizontally in front of the player, who sits on the floor. The right hand draws the bow (resined stick) across the strings while the left hand presses down on the strings to create vibrato, pitch bends, and slides. The player can vary the pressure and speed of the bowing to produce a wide range of sounds, from soft, smooth notes to rough, raspy tones. The instrument’s unfretted strings allow for continuous pitch modulation, giving the player significant control over dynamics and tonal expression. Mastering the ajaeng requires precise coordination between bowing and left-hand finger techniques, as well as an understanding of traditional Korean music’s expressive qualities.
Learning Difficulty	High; learning to play the ajaeng requires developing strong bowing techniques to control the instrument’s distinct raspy sound. The player must also master the left-hand techniques used to manipulate pitch and vibrato. The tension of the strings and the unique sound of the ajaeng make it challenging to produce a clean, steady tone, especially for beginners. Additionally, players need to learn traditional Korean music repertoire and performance techniques to fully appreciate the instrument’s role in ensembles and solo performances.
Notable Musicians or Composers	The ajaeng has been performed by notable musicians such as Kim Il-ryun and Kim Hee-sun, who have contributed to its prominence in both traditional and contemporary Korean music. Kim Il-ryun, in particular, has explored the instrument’s potential in modern fusion music. In modern times, composers such as Hwang Byung-ki have written innovative works for the ajaeng, blending traditional Korean music with modern compositional techniques. The National Gugak Center Orchestra regularly features the ajaeng in its performances of court and folk music, while modern bands like Jeong Ga Ak Hoe have incorporated the ajaeng into contemporary world music.
Famous Works	Traditional pieces such as “Ajaeng Sanjo” are key works in the instrument’s repertoire, showcasing the instrument’s ability to produce a wide range of dynamics and tones in solo performances. In modern compositions, Hwang Byung-ki’s “Forest” explores the ajaeng’s expressive capabilities, blending traditional Korean music with contemporary elements.
Notable Performances	The ajaeng is frequently performed in traditional Korean music festivals, cultural events, and concerts. Notable performances include recitals at the National Gugak Center, where the ajaeng is featured in traditional court music performances.
Maintenance	Proper maintenance of the ajaeng includes regularly cleaning the strings and body to remove dust and oil buildup. The bow should be rosined regularly to maintain its grip on the strings, and the strings should be checked for tension and replaced if worn or damaged. The instrument should be stored in a protective case and kept in a stable environment, away from extreme temperature and humidity changes, to preserve its sound quality.
Price Range	Ajaengs range in price from $1,000 to over $10,000, depending on the quality of materials, craftsmanship, and the number of strings.
