在西方中世纪时期,最引人注目的现象是宗教文化的繁盛,人们崇尚信仰的同时思想被教会统治。人们经过漫长时期的人文主义传统,理性一方面禁锢着文学的,另一方面却使音乐有了较大的发展。中世纪音乐时间范围很广,大部分的音乐都以宗教的目的为主。中世纪之后人们的思想普遍逐渐转化成自主理性,自主理性成了后期音乐发展的重要作用。本文针对中世纪音乐中的理性思维进行分析。 In the Western Middle Ages, the most striking phenomenon was the flourishing religious culture, in which people advocated beliefs and were ruled by the Church.
