后现代主义是在一百年以来的现代主义运动的基础上产生的,同时也源自现代主义的衰退。从美学角度来看,后现代主义表现了和现代主义的对立与决裂。在现代主义的顶峰时期,精英文化和大众文化属于两个截然不同的美感经验范畴,而在后现代主义的创作中,这种商品文化和高等文化之间的界限则趋向于崩溃瓦解。约翰?凯奇是后现代主义创作者的典型代表,他不仅涤荡了20世纪的音乐创作观念,而且打破了音乐最传统的物质基础和结构原则。他在推翻传统,实现后现代主义反理性、反秩序的同时,也达到了内心世界新的层面上的和谐统一。 Postmodernism came into being on the basis of one hundred years of modernist movement, but also from the decline of modernism. From an aesthetic point of view, postmodernism shows its opposition to and rupture with modernism. At the height of modernism, elite culture and mass culture belong to two distinct categories of aesthetic experience. In the postmodernist writing, the line between such commodity culture and higher culture tends to collapse and collapse. John Cage is a typical representative of the postmodernist creator, who has not only washed away the concept of music creation in the 20th century, but also broke the most traditional material basis and structural principle of music. While overthrowing tradition and realizing post-modernist anti-rationalism and anti-order, he also reached a new level of harmony in the inner world.
