本文认为西欧中世纪的单声音乐作为一种音乐表现体裁,从整体性和发展性的角度来看,“宗教”性和“世俗”性是统一于单声音乐的两大特征,而非两种音乐。纵向上表现为单声音乐“宗教”性和“世俗”性的不同发展阶段;横向上,表现为二者的并存和相互借鉴。 This paper argues that monaural music in the Middle Ages in Western Europe was a genre of musical expression. From a holistic and developmental perspective, “religious” and “secular” sexuality are two major characteristics unified in mono music, Not two kinds of music. Longitudinally, it manifests itself in different stages of development of mono music, “religion” and “secular” sexuality. In the horizontal direction, it manifests as the coexistence and mutual reference of the two.
