The Formal Structure and Narrative Musical Language of Ambush on All Sides (Pipa Repertoire) — 琵琶大曲《十面埋伏》的曲式结构与叙事性音乐语言

As one of the most iconic works in the Chinese pipa repertoire, Ambush on All Sides presents a vividly dramatic musical narrative based on the historical Battle of Gaixia between Chu and Han. Using formal structure as the analytical starting point, this study traces the work’s narrative trajectory—pre—war, mid—war, and post—war—through a close examination of pitch organization, rhythmic design, timbral contrast, and articulation patterns. Particular attention is given to the interaction between sectional design and performative layering, demonstrating how tempo, dynamics, instrumental technique, and timbre function not merely as expressive devices but as structural forces shaping the composition’s dramatic arc. Rather than a simple succession of contrasting episodes, the piece reveals a carefully constructed formal architecture in which performance practice plays a decisive role in articulating narrative logic. Through this structural–performative coupling, Ambush on All Sides exemplifies a core aesthetic principle of traditional Chinese instrumental music: the capacity to narrate history and convey emotional intensity through sound alone. 《十面埋伏》作为琵琶武曲的巅峰之作，以楚汉垓下之战为题材，构建了兼具戏剧性与逻辑性的音乐叙事体系。本文以曲式结构为切入点，结合音高、节奏、音色、句法结构等多维度进行分析，剖析作品“战前—战中—战后”的叙事脉络。在此基础上，探讨曲式结构与演奏层次的深度耦合关系，揭示其变化如何服务于情节推进与情绪表达，展现我国传统器乐“以音叙事、以乐传神”的艺术特质。
