Symbiosis of Technology and Expression: A Study on Modern Treatment Techniques of Pitch Material in "Northern Frontier Lights"

Abstract

Based on the ethnic pitch DNA of the a cappella chorus suite Northern Frontier Lights, this study systematically analyzes the work's modern treatment approaches to pitch material from three dimensions: pitch development techniques, methods of textural integration, and the logic of emotional expression. The research demonstrates that through modern compositional techniques, including pitch set transformation, control of tonal tension, fusion of multi-voice textures, and onomatopoeic pitch design, the work achieves creative development of ethnic pitch material. The pitch treatment techniques form a profound resonance with the natural landscapes of the northern frontier—such as deserts, grasslands, and forests—and the humanistic spirit of the Mongolian people, thereby accomplishing an organic unity of technical form and emotional connotation. This study provides concrete technical references for the "modern expression of traditional materials" in contemporary a cappella chorus composition.
