Development Law and Empirical Analysis of the Phenomenon of Acoustic Echo Regression in Music from the Perspective of Postmodernism
Postmodernism invades economy, politics and art and music with its powerful situation. With its innovative cultural spirit, it has deconstructed the original tonal center, destroyed the traditional rules and orderly, and moved towards a pluralistic form, forcing music to begin to seek new timbre and sound, and then to develop into a single imitation and presentation of sound. This phenomenon actually coincides with the retrospect of early human exploration of the sound of music: "imitating sound - returning to ancestors". From the perspective of imitation, this paper takes the collection and sorting out of the literature related to post-modernism and post-modernism music and the induction and summary of the phenomenon of imitation related to ancestors in the early stage as the theoretical basis. Subsequently, this paper makes a case study of the works (music score), the characteristics of the works, the particularization of the use of materials and the fragmentation of post-modernist music. Finally, from the aesthetic point of view, this paper combines the historical development and evolution of musical characteristics with the humanistic environment and cultural background of the society at that time, and explores the inevitability, essential connotation and aesthetic implication of the phenomenon of "imitating sound".
