Zaju

Zaju was a form of Chinese opera which provided entertainment through a synthesis of recitations of prose and poetry, dance, singing, and mime, with a certain emphasis on comedy (or, happy endings). Although with diverse and earlier roots, "zaju" has particularly been associated with the time of the Yuan dynasty (1271–1368), and "zaju" remains important in terms of the historical study of the theater arts as well as Classical Chinese literature and poetry. "Zaju" is known to have been performed during the earlier Song (960–1279) and Jin (1115–1234) dynasties. The various particulars of the "zaju" multimedia performance were derived from many and diverse sources of musical, dance, poetry, and theater traditions.
Characteristics.
The Yuan "zaju" were poetic music dramas comprising four acts, with the "act" (齣, "chu") defined as a set of songs following and completing a certain musical modal progression. Occasionally one or two "wedges" (楔子, "xiezi"), or short interludes in the form of an aria performed by another character might be added to either support or enhance the plot. Within the acts, lyrics were written to accompany existing tunes or set-rhythmic patterns; and, the major singing roles were restricted to one star per act. The "zaju" featured particular specialized roles for performers, such as "dan" (female), "sheng" (male), "hua" (花, painted-face) and "chou" (clown).
Background.
On one hand, the "zaju" theater is the product of a long process of Chinese art, music, and poetry; on the other hand, the "zaju" also appears as a phenomenon resulting from a combination of cultures of Eurasia over time. "Zaju" had its genesis even before the Yuan dynasty (1271–1368). "Zaju" was performed during the Song dynasty (960–1279), particularly the Northern Song period (960–1127), as well as the Jurchen Jin dynasty (1115–1234), which succeeded it in northern China. 
"Zaju" is now best known now from its high development during the Yuan dynasty, which was founded by the Mongol Empire under the leadership of Kublai Khan. Significant surviving literature exists from this period, including around two-hundred written scripts for "zaju" performances. Although the Yuan was the first non-Han dynasty to rule over China fully, varying ethno-musico influences had already made an effect upon the culture of China, most relevantly in terms of the mix of arts that went on to coalesce as the mixed "zaju" ("variety theater"): this encompassed poetry, gymnastics, orchestral music, set design, along with the other arts required for this complex form of theater art. Major questions remain about the relationships between this artistic and political process in regards to how it is known in relationship to the "zaju" form of art. The Yuan succeeded the previous dynasties which controlled parts of China: the Jurchen Jin dynasty, the Tangut Western Xia (1038–1227), and the Han Chinese Song dynasty. The transitions between the various political regimes tended to involve war, death, and disorder in a large scale. However, various cultural and artistic contributions from these diverse sources melded together to help form the "zaju" performances: musical modes of the steppes, traditional Chinese "shi" and "ci" poetry, the newly developed and embedded qu lyrics, acrobatics, and dance, combined together with the other varieties of artistic performance to contribute to the mix which "zaju" represents. Accompanying musical notation is evidently lacking; instead, the tune to which an aria was meant to be sung is indicated in the text by the title of a popular song or aria using the same tune. Generally, information about performances derives from preserved literary texts: arias, libretti, and/or other forms of stage direction.
Playwrights.
Much of the information on Yuan era plays (that is, "operas") and playwrights derives from a book written during this time period which is entitled "Register of Ghosts". Famous playwrights (that is, authors of "zaju") include Guan Hanqing, author of "The Injustice to Dou E", and the author Bo Renfu, who wrote three existing plays, plus a lost work on Emperor Xuanzong of Tang and his lady Yang Guifei. Wang Shifu wrote the popular play "Romance of the Western Chamber". Li Qianfu wrote "Circle of Chalk". Ma Zhiyuan has seven extant "zaju" plays.
Legacy.
"Zaju" represents a period in the development of the Chinese Opera. In terms of the history of theatrical performance, the "zaju"'s contributions to Chinese theater include the received legacies from previous forms of theatrical performance, the transformations based on the influence of these, and the legacy which the "zaju" performances in passed on to future performers and performances. On a more purely literary level, much of the poetry of the Yuan period is in the form of the "qu" poetry verse, which basically became an independent form of art, removed from its original theatrical and orchestral context: written after the model of the cadences, or set tone patterns, known from the arias of the "zaju" theater, the Chinese Sanqu poetry eventually became a separate tradition, in the category of poetic literature, rather than in the category of the performing arts. During the Yuan dynasty the prestige of both theater and of the use of vernacular language in art and literature were probably related to the fact that the new Mongol dominated regime less understood the older, classical language and forms. Rather, the new Mongol elite appreciated the theater and the use of vernacular language. Compared to the traditional Chinese "shì", or scholar-officials or emperors, the newcomers were not so literately erudite or oriented, much less were they appreciative of the ancient forms, expressions, and allusions, legacy of more than a millennia. "Zaju" took much of its characteristics from both this emphasis on the vernacular speech, as well as the lowered prestige of traditional scholarly literature. Also, founding emperor Khubilai Khan suspended the traditional civil service tests, which emphasized learning of the ancient classical tradition, thus both lowering the prestige of this course of learning and also reducing the opportunities for scholar-officials to engage in traditional career paths. This resulted in opportunities for aspiring playwrights to write for "zaju", both for those playwrights relatively new to literature and for those members of the traditional "shi" class who could no longer succeed as poets and essayists, and were willing to embrace the "zaju". The long-term legacy of the "zaju" theater was thus not only regarding the development of Chinese opera over subsequent centuries into the present day; but, also, despite the ensuing Ming dynasty restoration of prestige to legacy literary forms, the "zaju" form contributed to the increased prestige and popularity of vernacular forms such as the novel which ensued in the Ming dynasty literature.
