Technical Implementation and Emotional Communication Strategies of Charm in Ethnic Instrumental Music Performance
Main Article Content
Abstract
As the core aesthetic characteristic of ethnic instrumental art, charm is a highly unified expression of technique and emotion. It embodies the aesthetic pursuit and cultural spirit of Chinese national music. In response to the current problems of emphasizing technique over charm and generalizing emotional communication in ethnic instrumental performance, this article takes representative instruments such as erhu, guzheng, and bamboo flute as research objects and systematically explores the technical implementation path and emotional communication strategy of charm. The study first analyzes its aesthetic connotation and cultural origins, clarifying core characteristics such as the interplay of reality and virtuality, the fusion of emotion and scenery, and the combination of hardness and softness. It then examines how bowing, fingering, and breath techniques support charm, revealing the application logic of glissando, vibrato, breath control, and related performance methods. Although the research remains centered on music performance, its treatment of timbre, breath, and phrase-level signal variation provides a structured reference for broader wave-based expression analysis and human-centered signal interpretation in engineering communication. The study finally constructs an emotional communication system of technical foundation, emotional brewing, and artisticconception sublimation, clarifying the transformation mechanism from technical control to emotional resonance.
