Wennan Ci absorbs the excellent folk song material along the Yangtze River, is full of local flavor, has rich heritage and beautiful melody. Wennan's lyrics are rich in tunes and full of earthy aroma, and are known as nine tunes and eighteen tunes. There are more than 120 kinds of big and small tunes, with complete tunes and wide spread. The development of the vocal tune of Wennan Ci generally went through the "duplication of single songs" and "coupling of multiple songs" during the sitting singing period, forming the banqiang style behind the original opera. The singing tune is divided into three parts: minor tune, Wenci and Nanci. After entering Susong, the style of writing gradually became the "domestic style", and the ban styles include "zhengban", "adagio", "crying ban", "jiu ban", "yue ban", etc. After liberation, it was compiled and improved by musicians, and was divided into five types: "Laosheng Wenci", "Xiaosheng Wenci", "Danjiao Wenci", "Harlequin Wenci" and "Hualian Wenci", each with different characteristics such as accent and timbre. In terms of vocal range, they are divided into "male prose" and "female prose" based on the difference of four degrees. The male accent is high-pitched and steady, while the female accent is tactful and jumping. In particular, the alternation of "Shang" and "Zheng" in the text breaks through the local limitation of mainly "Zheng", thus greatly increasing the color. "Nan Ci" was mostly used by immortals, monks, nuns, and ghosts in the past. The words "Gong" and "Yu" complement each other in the style, so the tunes are elegant and refined, with unique charm.
The singing of Wennan Ci is mainly based on the real voice (natural sound range), which requires "crisp", "sweet", "round", "moist" and natural and smooth. In terms of accent style, "Wen Ci" is more exciting, "Nan Ci" is more elegant, and "Ping Ci" is more simple. During the singing, the accent is based on the words and the pronunciation of the words is highlighted. The first word of each sentence appears with stress, the words in the middle of the sentence are mostly vibrato, and the words at the end of the sentence are mostly with a downward tone.
