曲式结构的性质交混与时间结构的定量平衡——杜鸣心《小提琴协奏曲》第二乐章之曲式技巧解

Quantitative Balance between the Mixed Musical Structures and Time Structure--Explanation of form techniques in the second movement ofViolin Concerto by Du Mingxin

杜鸣心《小提琴协奏曲》的第二乐章为三部曲式。然而,其音乐整体运动是三部性、回旋性与二分性的纵向交混:三部曲式的音乐进程表明了该乐章曲式的基本状态和共性标准;主题在重复和简化的过程中,把对比中部与减缩再现复合在一起,形成与三部曲式结构的交混;变节拍构成“拍子数”168:168,其展现的时间“轨迹”形成了中心对称的“折射性”镜像结构。其结构的多重结合,使该乐章的音乐运动获得了定性和定量的双项平衡。

The second movement of Du Mingxin’s Violin Concerto is in ternary form.However,as this movement proceeds,a vertical mix of ternary and binary structures and cycles has formed.The progression of the piece in ternary form indicates the basic state and common standard of the musical form of this movement.In the process of repetition and simplification,the piece combines the middle-part contrasts with the middle-part reduction and reproduction to mix with the ternary structure.The ratio of variable beats to total beats is 168:168,and the time“track”indicated by this ratio forms a centrosymmetric“refractive”mirror structure.The combination of the multiple structures of this movement makes it qualitatively and quantitatively balanced.
