Equal Temperament
十二平均律
「十二平均律」（Equal Temperament）是一種音樂調音方式，它將音樂中的音階分成相等的音程，使得在所有調性中，各音之間的音程都是相等的。這種調音方式確保了在不同調性下演奏的音樂聽起來音高和諧，但也導致了某些音程的純度損失。
十二平均律是一種經常被使用的音樂調音系統，特別是在鍵盤樂器（如鋼琴）和許多現代樂器上。在十二平均律中，音階被分成 12 個等距的半音，每個半音之間的音程相同。這使得所有的音與音之間的音程都是相等的。
然而，十二平均律的使用也帶來了一些問題。在傳統的純律（Just Intonation）中，音程是根據純的整數比例來調整的，但在十二平均律中，音程被微調以達到均勻分配，這導致某些音程不再是純的，而是被微調的。這意味著在十二平均律中，某些音程的純度被犧牲，以確保各種調性下的和諧性。
十二平均律的一個重要優點是，它允許在不同調性之間進行平滑的轉調，而不會出現明顯的不協調。這對於現代音樂演奏和調音來說至關重要，特別是在需要在多種調性之間輕鬆切換的情況下。

G Song by Terry Riley
As an iconic American composer, Terry Riley (born 1935) is always considered as a minimalist. However, this kind of thoughts would be ignoring part of his creativity. In fact, Riley added plenty elements in his compositions since 1970s, especially when he started collaborating with the Kronos Quartet. Riley’s composing style is very extensive, including improvisation, polyrhythm and jazz. He adopted classical elements, such as instrumentation, musical forms, structure and tonality. He also combined the elements from different periods to create unique musical textures. This research focuses on Terry Riley’s String Quartet, G Song. The research will be divided into two parts. The first part introduces Riley’s life and the background of G Song. The second part focuses on music analysis, including the musical structure “Two forms in one work”; The harmony “Unresolved Dissonance”; The rhythm “Metric Modulation”; The baroque “Canon”; The modern “Pointillism”. The purpose of this study is to discuss how Riley combined classicism and modernism into a work, and discuss why the statement “Terry Riley is considered as minimalist” would be ignoring part of his story.
