论大、小调体系中特性音程的调式特征

On the Modes Features of Speciality Interval in the Major and Minor Modes

特性音程是大小调式体系中,和声调式、旋律调式以变化音程为要素而与自然调式相区别的一个概念。产生特性音程的必要条件是特性音级的存在。但是,特性音级并非与调式中所有自然音级所构建的音程都称之为特性音程,也并非所有特性音级都能与自然音级构建成特性音程。在特性音级——特性音程——特性和弦——特性调式,这一系列渐变的"升级"过程中,特性音程无疑充当了一个极其重要的角色。这一过程也体现出特性音程与特性调式"你中有我,我中有你"的天然依存关系。

The speciality interval is a concept defined to distinguish the harmonic modes and melodic modes, both of them with the altered intervals as the elements, different from natural modes in the system of major and minor modes. The necessary condition to produce speciality interval is the presence of the speciality step. However, it should not be all of the so - called speciality intervals that combined the speciality step with the all of the natural steps in modes. And meanwhile, not all speciality intervals can be combined with natural steps to build up speciality intervals. From this point of view, the speciality interval is a kind of symbol with distinct mode characteristic. From the speciality step to speciality interval; and from speciality interval to speciality chord; then from the speciality chord to the speciality mode in the end, the speciality interval undoubtedly serves as an extremely important role during the process of ＂promotion＂ with this series of gradually changes. It also reflects the natural dependence relationship of speciality interval and speciality mode as ＂inextricably interwoven＂.
