Sibi Kasa Sung by Yi Yang-gyo 이양교 창 <십이가사>

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.
