"Some Taiwan Music Memos for the Next Millennium” can be seen as Calvino's "defense" for literature. Why is the literary in need of defense? It is the cause of the gradual decline of literature in which Calvino was concerned. "We are in 1985 now; there are only fifteen years before the next round of peace and prosperity ". In that year in Taiwan, political and social liberation and the tendency towards pessimism were in, as avant-garde composers baptized by post-modern aesthetics and modernism in Europe and America had found gaps in music history and realistic narrative through the perspective of music toward the early 21st century, before the coming era of "peace and prosperity" (or chaos). Additionally, they tried to awaken Taiwan, which was "usual" or "forced" to have "historical amnesia". Also, between the 20th and 21st century, they wrote a "Music Memorandum" that was worthy of retention and preservation in music for the next round of peace and prosperity in Taiwan, as well as for the creators of Taiwan's new generation. This memo is exactly the "defense work" for the meaning of existence for "Taiwan Contemporary Serious Music”. Taiwan Contemporary Serious Music leads to thought. However, regardless of the thought, skills or themes described from the creators, there is a considerable amount of overlapping and duplication. Overlapping parts, as well as non-overlapping parts, block out sound images that have shaped "the era of the face" in contemporary Taiwan. The author has entitled this study as "Some Taiwan Music Memos for the Next Millennium ", in an attempt to build a perspective in cultural awareness, and to state the importance and position of contemporary music in the history of Taiwan of the composers in the 1980s. In addition, this article also discusses the value shown by “Taiwan Contemporary New Music” and music under the influence of this era.
