Comparative Analysis of Musical Morphology between Italian Opera Aria and Sichuan Opera Gaoqiang

This article systematically compares the musical morphology characteristics of Italian opera aria and Sichuan opera Gaoqiang. Through the analysis of structural design, performance techniques, emotional expression, modal system, and cultural values, it reveals the significant differences between the two in form and content. Italian arias emphasize a standardized structure, multi-layered harmonic system, and delicate melodic lines, expressing profound emotions and dramatic tension, reflecting European classical music's pursuit of individual expression and emotional depth. Sichuan Opera Gaoqiang, on the other hand, emphasizes the creation of artistic conception and the intuitive expression of the characters' psychology with its highly fluid structure, varied vocal modes, and rich national flavor, reflecting the emphasis of traditional Chinese opera on local culture and straightforward emotions. Through comparative analysis, this study provides a profound theoretical basis for understanding the differences between Chinese and Western musical expression and cultural values, which helps promote cross-cultural artistic exchange and innovative development.
