Qupai, also known as “paizi (tune labels),” refers to the melodic templates used in traditional Chinese music, which can be applied in numerous ways. Focusing on the Duanzhenghao taoqu (suite) of the Zhenggong mode in Northern Qu (Beiqu) as a case study, the author conducts a detailed analysis of the nine commonly used Qupai within it. Such an analysis examines a range of their core characteristics, including their standard lyric-meter structures, the developmental process of music and lyrics, common melodic materials, the melodic contours inherent in linguistic tones, and common structural arrangements. Although it cannot fully represent the entire picture of traditional Chinese Qupai, the study nevertheless explores the organizational logic and formal paradigms underlying the linked-Qupai structure.
