In the musical structure of opera, the vocal part is its main body. Traditional Chinese aesthetics believe that vocal singing is more intimate and moving than instrumental accompaniment, and can more easily arouse the audience's understanding and excitement. The reason is that although the music played by musical instruments can convey emotions, it cannot express meaning. Opera music depicts characters, and the main body relies on vocal music, that is, beautiful singing and moving singing. Regardless of whether the opera is qupai or banqiang, it can be divided into lyrical singing, narrative singing and dramatic singing. Lyrical singing is characterized by fewer words and more sounds, strong melody, and is good at expressing inner feelings; narrative singing is characterized by many words and few sounds, strong recitation, and is suitable for narrative and repartee situations; dramatic singing is mostly free in rhythm The loose board has great flexibility in the expansion and contraction of rhythm, so it is good at expressing passionate and strong emotions. The alternate use of these three types of tunes constitutes the ever-changing drama of opera music. Chinese opera has many traditional repertoires, and the reason why they have been sung on the stage for a long time is mainly due to their popular singing styles.

The art of opera singing has also formed its own unique style and professional skills in the long-term development. In singing, we pay attention to the relationship between words and sounds, sounds and emotions. Expressing the pronunciation and meaning of words clearly and accurately is the first requirement for singing skills, which has resulted in a series of singing methods and techniques. Singing generally includes vocalization, enunciation, breath use, decorative singing, etc. Its purpose is to express the thoughts and feelings of the characters in the drama. Singing the mood of the music and moving people with emotion are the highest aesthetic standards of singing art.

Singing and chanting are the two major components of opera vocal music. All the accomplished actors of all ages are excellent at singing and speaking. Singing and reciting the pronunciation of words is the basis for expressing expressions. The four tones of Chinese characters, the cadences and ups and downs, are also the basis for the beauty of the music in recitation. Various forms of recitation, such as Yun Bai, Jing Bai, and dialect Bai of Peking Opera, are the combination of language and music to varying degrees.

The contribution of the many actors in opera is nothing more than the creation of genres in singing. The genre singing style created by actors and musicians based on the tone of this play has more practical significance in music composition. The collaboration between Peking Opera performer Mei Lanfang and pianist Xu Lanyuan to create a tune is a typical example. The Mei (Lanfang), Cheng (Yanqiu), Xun (Huisheng) and Shang (Xiaoyun) schools of Danxing in Peking Opera, the Yu (Shuyan) and Ma (Lianliang) schools of Laoshengxing; Yue Opera The Yin (Guifang) and Fan (Ruijuan) schools of primary and middle school students, and the Fu (Quanxiang) and Qi (Yaxian) schools of Danxing are all schools that enjoy a high reputation in the art of singing.
