短簫

Gagok (가곡) is a refined genre of Korean courtly vocal music consisting of lyric song cycles set to sijo poetry and accompanied by a small jeongak ("proper music") orchestra. It exists in distinct repertoires for male (namchang) and female (yeochang) voices. Emerging from the aristocratic salon culture of late Joseon Korea, gagok shapes three-line sijo texts into extended, highly ornamented melodies in the ujo and gyemyeonjo modal systems. The accompaniment typically features a soft yet stately chamber ensemble (piri, daegeum, haegeum, gayageum or geomungo, and janggu) that articulates cyclical rhythms (jangdan) while sustaining a contemplative pace. Considered one of the most elegant vocal traditions within Korean classical music, gagok was recognized as a National Important Intangible Cultural Heritage in the 1960s and inscribed by UNESCO in 2010 as an Intangible Cultural Heritage of Humanity.
