The gayageum (가야금), also spelled, kayagum or kayageum, is a Korean string instrument belonging to the zither family, i.e., a musical instrument with a flat wooden sound box with multiple strings stretched across it, placed horizontally and played with the fingers.

The traditional gayageum sanjo (가야금 산조) is approximately 142 cm long by 23 cm wide by 10 cm deep. Paulownia wood is used as a soundboard while the back and sides are constructed of hardwoods such as chestnut or walnut. The gayageum sanjo has 12 silk strings, although modern instruments may have as many as 25 strings. On the soundboard, anjok (bridges) are used to support the strings. These bridges may be moved to adjust tuning and intonation. The gayageum is closely related to other Asian instruments, including the Chinese guzheng and Japanese koto.

According to Korean legend, the gayageum was developed during the 6th century in the Gaya confederacy by King Gashil after encountering a Chinese guzheng. Hence, the name literally means "zither of Gaya,"i.e., from 가야 ( gaya, “Gaya confederacy”) plus 금 (geum, “zither”). However, archaeological excavations in the Jeolla-namdo Province have uncovered fragments of a gayageum from the 1st century BCE, suggesting the gayageum is considerably older than the 6th century.

This ancient gayageum of King Gashil is called the pungryu or Jeong ak gayageum and is associated with court music, chamber music, and lyric songs. The pungryu gayageum is larger and uses more widely spaced strings than the sanjo and modern gayageum.
The gayageum sanjo is the most popular form of the instrument. It developed in the 19th century along with the emergence of sanjo music. Sanjo means scattered melodies and pieces often features fast tempos and improvisation after a slow introduction. The gayageum sanjo version of the instrument has closer string spacing and a shorter length than the ancient Jeong ak gayageum, enhancing the performance of fast passages. Traditional gayageum use silk strings, although some modern performers have switched to nylon strings.

Modern gayageum with more than 12 strings tend to be strung with nylon-wrapped steel strings, similar to those on the Chinese guzheng and pipa. This change in materials and number of strings yields increased volume and pitch range for contemporary music use.

The traditional gayageum is played sitting on the floor with crossed legs, the lower bout of the instrument on the right knee and the lower bout on the floor. Modern gayageum is played elevated on a stand with the player seated or standing behind the instrument.
Gayageum is played directly with hands: right hand plucks, strums and flicks the strings near the bridge while the left hand pushes the strings on the left side of the bridges to change pitch and add vibrato and ornamentation. The gayageum's tone is soft, delicate, and subtle, about the same volume as a tenor ukulele.

Gayageum Byeongchang is a traditional Korean musical style where singers accompany themselves on gayageum. We'll listen to "Saetaryeong," (say-ta-ri-young) an example of Namdo Minyo (남도민요), folk song from the southern region of Korea. The lyrics speak of birds, good fortune, good harvest and the coming of Spring. Bird song is imitated in the melody, i.e., owl, krane, and barn shallows.
