刘天华二胡曲旋律创作中的调式音列思维

The Mode Logic of the Melody Composition in Liu Tianhua's Erhu Music

作为中国传统的旋律发展手法,"衍展"一般表现为调式音列材料有序的滚动,也有可能在滚动的同时,通过装饰(重复音型、加花变奏、音区变换等)逐渐地加入一些新的音高材料而使音乐发展起来。刘天华在他的二胡曲旋律创作中,巧妙地将调式音列材料进行分割、组合,从中可以看到不同作品中调式音列材料的同源性以及双重的调式音列线条,甚至可以看到音级集合形态。所有这些现象正是建立在调式音列思维基础之上的。因此,透过旋律的衍展来认识调式音列思维,或许是解读刘天华旋律创作奥秘的一种方法。

As a Chinese traditional technique of melody development,derivation usually shows the sequential rolling of the mode materials,which is sometimes accompanied by some gradual additions of new pitch materials in order to develop the music,depending on some ornaments：figure repetition,decorative variation,changing register and so on.Mr.Liu Tianhua ingeniously applies separation and combination to the mode materials in the melody composition of his Erhu music.In this process,we can find the homologies of the mode materials in different works and also the dual mode lines,even the pitch-class set can be found.All of these appearances are based on the mode logic.Therefore,we recognize the mode logic through the melody derivation,which perhaps can be considered as a method of exploring the secrets in Mr.Liu＇s melody composition.
