Mechanism
Aak takes the Confucian sacrificial job from yayue: hymn and offering as the architecture, a tuned bell-and-lithophone set, and the same name. Strength high. The dated carrier is the Song gift of instruments and musicians to Goryeo in 1116. Hyangak and dangak are other Korean court wings, not this edge.
Evidence
The 1116 gift; pyeonjong and pyeongyeong as the Korean ritual set; Munmyo and Jongmyo as living Confucian rites. Joseon recomposes much of the sung repertory (Sejong and after); the job and the kit stay.
- Confucian sacrificial job, bronze-and-stone ritual set, and the name 雅樂 / 아악 transplanted as aak
- pyeonjong / pyeongyeong (1116 — Korean names of the Chinese bianzhong / bianqing set in the Song gift)
Debate
How much living aak melody is Song versus Joseon composition. Consensus: the system travels; a large part of the sounding book is Korean. Do not parent aak from Gagaku or treat the two as one “East Asian court” node.
