What is gugak? A beginner's guide to Korean traditional music
TUREFF• •0
Gugak means, literally, "national music", and in practice it covers the traditional music of Korea, from slow court ritual to raucous village drumming. If you have heard a gayageum in a drama soundtrack or a pansori singer in a film and wondered where it fits, this guide gives you the map.
Two broad families
Korean traditional music is usually divided into two groups.
Jeongak, sometimes translated as "proper" or "correct" music, is the music of the court, the aristocracy and the literati. It tends to be:
- slow, stately and meditative
- played for rituals, banquets and refined private gatherings
- carefully notated and transmitted
Examples include Jongmyo jeryeak, the ritual music performed for royal ancestors at Jongmyo Shrine in Seoul, which UNESCO recognised in 2001, and gagok, an elegant art song with ensemble accompaniment.
Minsogak, folk music, comes from ordinary people. It tends to be:
- more emotional and rhythmic
- tied to work, festivals, shamanic ritual and entertainment
- passed on by ear, with room for improvisation
The main forms of folk music
- Pansori: a long sung story performed by one singer with one drummer. The singer moves between singing, speech and gesture, sometimes for hours. It was recognised by UNESCO in 2003.
- Sanjo: solo instrumental music, literally "scattered melodies". A soloist on gayageum, geomungo, daegeum, haegeum or another instrument plays with a janggu drummer through a series of movements that start slowly and grow faster. It is a virtuoso form and closely linked to the expressive style of pansori.
- Minyo: folk songs. Every region has its own, and Arirang is the most famous. Folk songs from the southwest tend to sound sorrowful and deeply ornamented; those from Gyeonggi province around Seoul are brighter and lighter.
- Pungmul: village percussion and dance, played outdoors in a procession at festivals and farming events.
- Samul nori: a stage form developed in 1978 from pungmul, played by four musicians on four percussion instruments: the kkwaenggwari (small gong), jing (large gong), janggu (hourglass drum) and buk (barrel drum). It moved the energy of outdoor village music indoors and became one of the best-known Korean performing arts abroad.
- Shaman ritual music (gut music) is another important strand, with regional styles.
How it sounds different
If you are used to Western music, a few features stand out:
- Breath-based rhythm: tempo often follows a long breathing cycle rather than a strict metronome.
- Jangdan: rhythmic cycles played on the janggu that define a piece's feel, from very slow to very fast.
- Sigimsae: ornaments, bends and vibrato on individual notes. The colour of a single note matters as much as the melody.
- Space: silence and slowness are part of the music, particularly in court music.
Gugak today
Gugak is taught at specialist schools and universities, performed by national and regional orchestras, and kept alive by heritage holders. There is also a lively contemporary scene that mixes traditional instruments and singing with pop, jazz, rock and electronic music, which has introduced gugak to many younger listeners.
Where to start listening
- A short gayageum sanjo, for melody and ornament.
- An excerpt of pansori with subtitles, ideally a famous scene from Chunhyangga.
- A samul nori performance video, for sheer energy.
- A few minutes of Jongmyo jeryeak, to hear the court side.
Comparing these four gives you a feel for the range in an evening.
