“均”“调”距离论——中西调式建构力度与适应性差异的内在机制研究

On the Distance Between"Yun"and"Mode"——Research on the Internal Mechanism of the Differences in the Construction Strength and Adaptability Between Chinese and Western Modes

中西调式的建构力度具有明显的强弱差异。这种差异,与它们共同的五度链基础结构(均)的弹性机制相关。西方偏离五度链中心的大小调体系由于受五度链中心的控制作用较小,故能拉开与五度链基础结构的距离,显示出其强劲的调式建构力度;中国以五度链为中心匀称环绕的多调式体系则由于受五度链中心的明显控制,故与五度链基础结构较为贴近,其调式建构力度相应减弱。中西调式建构力度的“刚”“柔”差异,决定了其旋律形态对外部因素影响的适应性差异。

The construction strength of Chinese and western modes is obviously different.This difference is related to the elastic mechanism of their common chain of fifths(yun)infrastructure.Because the western major and minor system deviating from the center of chain of fifths is less controlled by the center of chain of fifths,it can open up the distance from the basic structure of chain of fifths and show its strong modal construction strength;the Chinese multi-modal system with the chain of fifths as the center and symmetrical surrounding is closer to the basic structure of the chain of fifths because it is obviously controlled by its center.Correspondingly,the construction strength of its mode weakens.The difference of"hardness"and"softness"in the construction strength between Chinese and Western modes determines the adaptability difference of its melody form to external factors.
