“五度相生链”与“雅”“俗”辩证观——“清声”俗乐论

On the Chain of Generation by Fifth Degree with Distinction of Noble and Vulgar

"五度相生链"指按纯五度关系排列的音或律形成的链条,是研究中国音乐用律的关键。本文从十八律入手,借用音分值理论、现代音程常识,摘用《乐府杂录》、《新唐书》、《宋史》、《清史稿》的相关内容,引入"位"的概念,辩证地探索俗乐音阶:清乐和燕乐都是俗乐、可从"清声"研究俗乐、四变即"和"不用"清角"、燕乐阶位七即"闰"不用"清羽"、清乐阶位七即"闰宫"不用"变宫"、"闰角"可从不同角度解释为"闰音的变化""闰宫""正角""徵角"。

The chain of generation by fifth degree means the notes or temperament arranging in a chain of pure fifth relationship, which is the key of research the temperament used in Chinese traditional music. The paper discussed the Su-music scale, and sort out Qing-music and Yan-music in Su.
