Chinese classical poetry art songs are one of the important genres in vocal works. The interpretation of each piece place high demands on the singer’s breath control, timbre, and expression of song connotations. With a long history of development and diverse stylistic classifications, they evoke varied emotional responses. A song primarily consists of two components: poetry and music. Poetry uses textual composition to shape poetic imagery, while music employs musical elements to create artistic images. These two elements complement and permeate each other. The integration of poetry and music better serves the presentation of artistic works, interprets the song’s artistic conception, and realizes the essence of Chinese classical aesthetic conceptions—the “Dao” that connects to the cosmic essence and life. Through specific research on the aesthetic harmony between poetry and music, this study clearly demonstrates the path of poetic-musical coexistence in Chinese classical poetry art songs.
