创作是音乐要素运动逻辑的形成过程，分析是音乐要素运动逻辑的辨析过程。文章以音乐要素的运动逻辑为出发点，阐述了如何理解音乐的本体。文章选取了贝多芬第一、第二十三钢琴奏鸣曲以及秦文琛的《琵琶辞》三首作品为例，提出了音乐要素运动逻辑的“严谨性”和“独特性”决定了音乐作品的“完成度”和艺术价值。

Creation is the process of the forming logical motion of musical elements,while analysis is the process of distinguishing the logical motion of musical elements.Starting from the motional logic of musical elements,this article elaborates on how to understand the essence of music with Beethoven's first and twenty third piano sonatas,as well as QIN Wenchen's“Pipa Ci"as examples.The emphasis on the “rigor”and“uniqueness"of the motional logic determines the completeness and artistic value of a musical work.
