Yayue () was a form of classical music and dance performed at the royal court and temples in ancient China. The basic conventions of yayue were established in the Western Zhou. Together with law and rites, it formed the formal representation of aristocratic political power.
The word ya () was used during the Zhou dynasty to refer to a form of song-texts used in court and collected in Shijing. The term yayue itself appeared in Confucius' Analects, where yayue was considered by Confucius to be the kind of music that is good and beneficial, in contrast to the popular music originated from the state of Zheng which he judged to be decadent and corrupting. Yayue is therefore regarded in the Confucian system as the proper form of music that is refined, improving, and essential for self-cultivation, and one that can symbolize good and stable governance. It means the kind of solemn ceremonial music used in court, as well as ritual music in temples including those used in Confucian rites. In a broader sense, yayue can also mean a form of Chinese music that is distinguishable from the popular form of music termed (俗樂) or "uncultivated music", and can therefore also include music of the literati such as qin music.
The court yayue has largely disappeared from China, although there are modern attempts at its reconstruction. In Taiwan yayue is performed as part of a Confucian ceremony, and in China in a revived form as entertainment for tourists. Other forms of yayue are still found in parts of East Asia, notably the gagaku in Japan, aak in Korea, and nhã nhạc in Vietnam. Although the same word is used in these countries (but pronounced differently), the music does not necessarily correspond to Chinese yayue. The Korean aak, however, preserved elements of Song dynasty yayue long lost in China.
History
According to tradition, yayue was created by the Duke of Zhou under commission from King Wu of Zhou, shortly after the latter's conquest of Shang. Incorporated within yayue were elements of shamanistic or religious traditions, as well as early Chinese folk music. Dance was also closely associated with yayue music, each yayue pieces may have a ceremonial or ritual dance associated with it. The most important yayue piece of the Zhou dynasty were the Six Great Dances, each associated with a legendary or historical figure – Yunmen Dajuan (雲門大卷), Daxian (大咸), Daqing (大磬, or Dashao 大韶), Daxia (大夏), and Dahu (大濩), Dawu (大武).
The Book of Rites records a number of situations where yayue might be performed. These included ceremonies in honour of Heaven and Earth, the gods or the ancestors. There were also detailed rules on the way they were to be performed at diplomatic meetings. Yayue was also used in outdoor activities, such as aristocratic archery contests, during hunting expeditions, and after the conclusion of a successful military campaign. Yayue was characterised by its rigidity of form. When performed, it was stately and formal, serving to distinguish the aristocratic classes. It was sometimes also accompanied by lyrics. Some of these are preserved in the Book of Songs.
With the decline of the importance ceremony in the interstate relations of the Spring and Autumn period, so did yayue. Confucius famously lamented the decline of classical music and the rites. Marquess Wen of Wei was said to prefer the popular music of Wey and Zheng to the ancient court music, listening to which he may fall asleep.
Much of the yayue of the Zhou dynasty continued into the Qin dynasty. However, some pieces appeared to have been lost or were no longer performed by the Han dynasty, and the content and form of yayue was modified in this as well as the succeeding dynasties. For example, the terrace ensemble (dengge) in yayue involved singings but not string instruments in the Han Dynasty, and in Sui dynasty, singers and string instruments were added to the court ensembles. During the Tang dynasty components of popular music were added to yayue. However, the dominant form of music in the Sui and Tang court was the entertainment music for banquets called yanyue (燕樂), and the term yayue became reserved for the music of Confucian rituals used in temples of the Imperial Family and the nobility as well as in Confucian temples.
