“错乱节奏”是钢琴音乐中常可见到、但较少被人专门讨论的概念。这一概念与音乐的“织体”范畴有着密切的关系,也跟音乐的曲式、体裁、风格等其他范畴有间接的关联。对这个问题的探讨有助于推进钢琴音乐的织体形态研究,也对于钢琴教学与演奏有一定的辅助作用。本文对于“错乱节奏”的基本形态和主要功能进行了一定的研究,其核心宗旨是提供一种观察音乐的角度和路径,以充实钢琴的初中级学者们应对不规则节奏和复杂织体的知识储备。 “Disorder rhythm ” is often seen in piano music, but less the concept of special discussion. This concept is closely related to the category of music “fabric ” and also indirectly related to other forms such as music, genre and style.

In this paper, we study the basic form and main functions of “disorder rhythm ”, and its core purpose is to provide a perspective and path to observe music in order to enrich the junior and mid-level piano students to deal with irregular rhythms and complex weaves Knowledge reserve.
