德彪西的作品中常使用多种音阶类型、简短而多样的音乐材料、三全音独立、和弦平行进行及弱化终止式等不同于德奥体系创作思维和调性音乐写作的技法，造成在分析他作品时对结构组织方式理解上的困惑。文章借鉴以三全音与纯五度音程交替为结构组织原则的观点，并在此基础上结合持续音与声部级进线条的贯穿，构成观察乐曲深层结构支撑的分析视角。然后，通过对德彪西三首器乐作品在材料构成、声部进行与结构组织的分析，说明此种分析视角的适用性及在实际运用时的灵活性。

In his works,Debussy often applies technical devices including various types of scales,short yet diverse musical materials,chordal parallel motion,and weakened cadential progression,which seems different from the principles of structural organization in the common practice period and causes confusion in analyzing the structural organization of his works.This article draws on the concept of the intervallic alternation of tritone and perfect fifth as the principles of structural organization,and on this basis,combines the pedal tones and the voice- leading by step motion throughout as the analytical perspective of the inner-structural support of the music.Then, by analyzing the material construction,voice-leading,and structural organization of Debussy's three instrumental works,the applicability of this analytical perspective and its flexibility in practical application are demonstrated.
