As a part of Chinese national culture, traditional Chinese music has developed in a unique way over many years through continuous changes and developments. Traditional Chinese singing art serves as the main carrier for Chinese national music and is also an outlet for cultural and aesthetic expression. Over time, the various forms, techniques and artistic ideas of Chinese singing art have been continuously expanding and developing. It has a long history and has greatly contributed to the development of Chinese national vocal music in recent years. Its theoretical systems, technical systems and genre structures are all very complex, so a systematic review of the singing art of all Chinese ethnic groups is a very difficult task. Among all the various ethnic groups in China, the traditional culture and singing arts of the Han majority differ considerably from those of the ethnic minorities. Therefore, in the study of traditional Chinese singing art, this paper will focus on the Han style. Through an organised study of the ontology of traditional Chinese singing art, this paper aims to uncover its deep-seated structure and culture.
