Yuan Drama Tune Patterns (*Yuanqu paidiao*) in the landscape of classical Chinese drama and *sanqu* (lyric verse) is the first-generation source code of the Huaxia tradition of classical drama and *sanqu* -- born of the historical pressures, from the Jin dynasty to the late Yuan (12th to 14th century), of the suspension of the civil-service examinations, the downward dislocation of intellectuals, marketplace entertainment in the pleasure quarters (*goulan*), the fusion of foreign banquet music, and the systematization of tune patterns -- defined as a composite audiovisual application system and tune-pattern music interface comprising *zaju* (variety plays: four acts plus one wedge, singing-speaking-acting-acrobatics, and role categories) and *sanqu* (short lyrics (*xiaoling*) and suites (*taoshu*) with tune-pattern prosody). A single continuous line must be traced to the end: from Jin-dynasty *zhugongdiao* (medley in various modes; Kong Santong and Dong Jieyuan) through the Four Great Masters of the early Yuan (Guan Hanqing, Bai Pu, Ma Zhiyuan, and Zheng Guangzu) through Wang Shifu's *Xixiang Ji* (Story of the Western Wing) through the mid-Yuan grand synthesis of *sanqu* (Zhang Kejiu, Qiao Ji, Guan Yunshi, and Sui Jingchen) through late-Yuan and early-Ming drama historiography (Zhong Sicheng and Xia Tingzhi) to Ming-dynasty systematization of tune patterns (Zhu Quan and Zhou Deqing).
The earliest textual anchor is the Jin-dynasty *zhugongdiao*, with Kong Santong (active in the 12th century, during the reign of Jin Emperor Zhangzong) as the creator of the *zhugongdiao* form. His invention of the *zhugongdiao* (a multi-mode connected-suite narrative singing form, linking multiple suites in different musical modes; c. mid-to-late 12th century) gave Kong Santong and the *zhugongdiao* in the Jin dynasty their foundational position as the multi-mode connected-suite narrative singing form. The continuation of the *zhugongdiao* was accomplished by Shang Zhengshu (c. late 12th to early 13th century) and his *Shuangjian Xiaoqing Zhugongdiao*. The grand synthesis of the *zhugongdiao* was accomplished by Dong Jieyuan (c. late 12th to early 13th century; dates disputed, traditionally placed during the reign of Jin Emperor Zhangzong, Wanyan Jing), whose *Xixiang Ji Zhugongdiao* (8 scrolls, 188 suites, 14 musical modes, 151 tune patterns; composed approximately between the first year of Mingchang and the fifth year of Cheng'an, 1190--1200 CE, c. 1190) -- the dramatic precursor of the Western Wing story -- gave Dong Jieyuan in the Jin dynasty his foundational position as the grand synthesizer of the *zhugongdiao*.
The founding of Yuan *zaju* by the first of the Four Great Masters was accomplished by Guan Hanqing (approximately 1220--1300 CE), the first of the Four Great Masters of Yuan drama and the Sage of Qu. With 18 extant *zaju* plays, approximately 70 *sanqu* suites, approximately 50 short lyrics, and the landmark works *Dou E Yuan* (The Injustice to Dou E, c. 1250--1260), *Dandao Hui* (The Single-Sword Meeting, c. 1260--1280), *Jiu Fengchen* (Rescued by a Courtesan, c. 1260--1280), and *Wangjiang Ting* (The Riverside Pavilion, c. 1260--1280; approximately 1250--1290, during the Zhiyuan era of Emperor Shizu), this gave Guan Hanqing in the early Yuan his foundational position as the founder of Yuan *zaju* and the Sage of Qu. The advancement of Yuan *zaju* as the second of the Four Great Masters was accomplished by Bai Pu (1226--1306 CE), with *Wutong Yu* (Rain on the Parasol Trees, c. 1260--1280) and *Qiangtou Ma Shang* (Over the Wall on Horseback, c. 1260--1280), as well as the *sanqu* pieces *Tianjingsha* and *Chenzui Dongfeng* (approximately 1250--1290). The advancement of Yuan *zaju* as the third of the Four Great Masters and the Champion of Qu was accomplished by Ma Zhiyuan (1250--1321 CE), the Champion of Qu (*qu zhuangyuan*), with the *zaju* *Hangong Qiu* (Autumn in the Han Palace, c. 1270--1290) and the *sanqu* *Tianjingsha, Qiusi* (Withered vine, old tree, dusk crow -- *kuteng laoshu yaya*) and *Yexingchuan, Qiusi* (A hundred years of light, like a dream -- *baisui guangyin ru meng*; approximately 1270--1320). The advancement of Yuan *zaju* as the fourth of the Four Great Masters was accomplished by Zheng Guangzu (?--1330 CE), with *Qiannyu Lihun* (The Soul of the Lovely Lady Departs Her Body, c. 1280--1320) and other works (approximately 1280--1330).
The other pole of Yuan *zaju* -- the dramatization of the Western Wing story -- was accomplished by Wang Shifu (approximately 1260--1336 CE), whose *Xixiang Ji* (Story of the Western Wing, 5 *ben*, 21 acts; approximately 1290--1310, during the Yuanzhen to Dade eras) gave Wang Shifu in the mid-Yuan his foundational position as the dramatization of the Western Wing story. The grand synthesis of *sanqu* was accomplished by Zhang Kejiu (approximately 1270--1348 CE), the Li [Bai] and Du [Fu] of Qu, whose 855 *sanqu* lyrics in approximately 40 tune patterns and the *Xiaoshan Yuefu* (6 scrolls; approximately 1310--1340) gave Zhang Kejiu in the late Yuan his foundational position as the grand synthesizer of *sanqu*. The other pole of *sanqu* was advanced by Qiao Ji (?--1345 CE), with *Liangshi Yinyuan*, *Yangzhou Meng*, *Jinqian Ji*, and *sanqu* pieces *Manting Fang* and *Shuixianzi* (approximately 1310--1345). The ethnic fusion dimension of *sanqu* was advanced by Guan Yunshi (1286--1324 CE, of Uyghur ethnicity), whose *Suantian Yuefu* and *Xihu Shiyong* (approximately 1300--1320) gave Guan Yunshi his foundational position as the ethnic-fusion dimension of *sanqu*. The marketplace satire dimension of *sanqu* was realized by Sui Jingchen (dates unknown), whose suite *Gaozu Huanxiang* (The Founder Returns Home, approximately 1300--1320) gave Sui Jingchen his foundational position as marketplace satire in *sanqu*.
The historiographic compilation of Yuan drama was accomplished by Zhong Sicheng (approximately 1275--1345 CE) of the late Yuan and early Ming, whose *Lugui Bu* (Register of Ghosts, completed in the first year of Zhishun, 1330, 2 scrolls), recording approximately 150 Yuan dramatists, gave Zhong Sicheng and the *Lugui Bu* in the late Yuan and early Ming their foundational position as the historiographic compilation of Yuan drama. The biographical compilation of Yuan drama performers was accomplished by Xia Tingzhi (dates unknown) of the late Yuan, whose *Qinglou Ji* (Green Bower Collection, completed during the Zhizheng era, c. 1360, 1 scroll), recording approximately 120 performers, gave Xia Tingzhi and the *Qinglou Ji* their foundational position as the biographical compilation of Yuan drama performers.
The systematization of Yuan drama tune patterns was accomplished by Zhou Deqing (dates unknown--1361 CE) of the late Yuan, whose *Zhongyuan Yinyun* (Sounds and Rhymes of the Central Plain, completed in the first year of Taiding, 1324, 2 scrolls) established the standardization of *qu* rhyme with 19 rhyme categories (*Dongzhong*, *Jiangyang*, *Zhisi*, *Qiwei*, *Yumu*, *Jielai*, *Zhenwen*, *Hanshan*, *Huanhuan*, *Xiantian*, *Xiaohao*, *Gege*, *Jiama*, *Chezhe*, *Gengqing*, *Youhou*, *Qinxun*, *Jianxian*, and *Lianxian*) as the framework, giving Zhou Deqing and the *Zhongyuan Yinyun* in the late Yuan their foundational position as the standardization of *qu* rhyme. The taxonomic systematization of tune patterns was accomplished by Zhu Quan of the early Ming (1378--1448 CE), whose *Taihe Zhengyin Pu* (Anthology of the Grand Harmony of Correct Sounds, completed in the 31st year of Hongwu, 1398, 2 scrolls) recorded 585 tune patterns classified by 12 musical modes and 12 categories of *zaju*, giving Zhu Quan and the *Taihe Zhengyin Pu* in the early Ming their foundational position as the taxonomy of tune patterns.
The realization of Yuan drama tune patterns as the Ming-Qing afterglow was accomplished in the mid-to-late Ming by Tang Xianzu (1550--1616 CE), whose *Linchuan Si Meng* (Four Dreams of Linchuan: *Zichai Ji*, *Mudan Ting*, *Nanke Ji*, and *Handan Ji*; c. 1590--1610) exemplified the Ming *chuanqi*, giving Tang Xianzu his foundational position as the Ming *chuanqi* afterglow of Yuan tune patterns. The Qing-dynasty afterglow was realized by Hong Sheng (1645--1704 CE) and Kong Shangren (1648--1718 CE), with Hong Sheng's *Changsheng Dian* (Palace of Eternal Life, completed in the 27th year of Kangxi, 1688, 50 acts) and Kong Shangren's *Taohua Shan* (Peach Blossom Fan, completed in the 38th year of Kangxi, 1699, 44 scenes plus 1 intercalary scene), giving Hong Sheng and Kong Shangren in the early Qing their foundational position as the Qing *chuanqi* afterglow of Yuan tune patterns.
The internal logic of Yuan Drama Tune Patterns runs from the Jin-dynasty *zhugongdiao* (Kong Santong and Dong Jieyuan) through the Four Great Masters of the early Yuan (Guan Hanqing, Bai Pu, Ma Zhiyuan, and Zheng Guangzu), Wang Shifu's *Xixiang Ji*, the mid-Yuan *sanqu* grand synthesis (Zhang Kejiu, Qiao Ji, Guan Yunshi, and Sui Jingchen), the late-Yuan and early-Ming drama historiography (Zhong Sicheng and Xia Tingzhi), the Ming-era systematization of tune patterns (Zhu Quan and Zhou Deqing), and the Ming-Qing afterglow (Tang Xianzu, Hong Sheng, and Kong Shangren). Throughout, the underlying logic has always been the same single statement: under the historical pressures of the suspension of the civil-service examinations, the downward dislocation of intellectuals, marketplace entertainment in the pleasure quarters, the fusion of foreign banquet music, and the systematization of tune patterns, hard-coding music, lyrics, spoken dialogue, gesture, and acrobatics into a composite audiovisual application system integrating 12 musical modes, approximately 400 tune patterns, singing-speaking-acting-acrobatics, and role categories (*sheng*, *dan*, *jing*, *chou*) (that is, the 12-mode music interface, the approximately 400-tune-pattern containers, the singing/speaking/acting/acrobatics audiovisual pipeline, and the *sheng*/*dan*/*jing*/*chou* role-division) was the most fundamental mechanism by which classical Chinese drama could integrate literature, music, theater, dance, and acrobatics into a single audiovisual application protocol. The four characters *Yuanqu paidiao* could become an enduring name for the composite audiovisual application system and tune-pattern music interface in the Chinese language precisely because they compress thirteen groups of author-date-context lineage -- Kong Santong, Dong Jieyuan, the Four Great Masters (Guan Hanqing, Bai Pu, Ma Zhiyuan, and Zheng Guangzu), Wang Shifu, the *sanqu* masters (Zhang Kejiu, Qiao Ji, Guan Yunshi, and Sui Jingchen), the historiographers (Zhong Sicheng and Xia Tingzhi), the tune-pattern systematizers (Zhu Quan and Zhou Deqing), and the *chuanqi* inheritors (Tang Xianzu, Hong Sheng, and Kong Shangren) -- into just four characters.
