조순자 여창 가곡전집 <첫째바탕, 둘째바탕, 셋째바탕>

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.

Jeongak is the refined classical court and aristocratic music of Korea, encompassing ritual (aak), Chinese-derived (dangak), and native court (hyangak) traditions under a broader aesthetic of elegance, restraint, and balance. It is performed on an ensemble of wind, string, and percussion instruments such as piri and daegeum (oboes and transverse bamboo flutes), haegeum (two‑string fiddle), gayageum and geomungo (zithers), and various drums and gongs. The style emphasizes calm tempi, cyclical rhythmic patterns (jangdan), heterophonic texture, and subtle ornamentation (sigimsae and nonghyeon). Core repertory includes suites like Yeongsanhoesang and Boheoja and the stately music for royal ancestral rites (Jongmyo Jeryeak). Jeongak is closely associated with Confucian court culture and literati ideals, privileging poise, precision, and contemplative beauty.
