Neapolitan Sixth
♭II6
「Neapolitan Sixth」是音樂理論中的一種和弦類型，通常在常見的和聲體系中使用，特別是在古典和浪漫時期。「Neapolitan Sixth」以其獨特的音色和創造和諧張力和釋放的能力而聞名。
「Neapolitan Sixth」是建立在音階的降二度（在小調中）或降六度（在大調中）上的。它由根音、距根音小三度和距根音減五度組成。這創造出一個獨特且稍微不和諧的音色，需要釋放。
「Neapolitan Sixth」出現後通常會釋放至屬音和弦或主音和弦，而 「Neapolitan Sixth」的減五度通常會向外移動半音到屬七和弦的三度，同時根音向下移動半音到屬七和弦的五度。

樂聖：貝多芬
路德維希·范·貝多芬，德國作曲家，古典至浪漫過渡時期間的主要音樂人物。他在西方音樂史上佔有前所未有的統治地位，一直被廣泛認為是有史以來最偉大、最具影響力、最受歡迎的音樂家。
貝多芬的音樂傳承了海頓和莫札特的古典藝術氣息、滲透了個人對尊嚴的渴望、宣洩了他被命運折磨的憤怒、展示了他與命運抗衡的決心。
比起任何一位音樂家，貝多芬能夠更有力地透過音樂與聽眾交互生活哲學。儘管他不是浪漫主義者，卻成為了其他浪漫主義者所追隨的對象。
貝多芬是一位音樂創新者，他拓寬了奏鳴曲、交響樂、協奏曲和四重奏的規模。在貝多芬第九交響樂《快樂頌》之中，他以前所未有的方式將聲樂和器樂結合在一起。
作為音樂家，貝多芬飽受耳疾折磨。然而，他不甘於向命運屈服，誓要扼住命運的咽喉，繼續去完成他的事業。他在生命中的最後十餘年，在完全聽不到聲音的情況下，寫下了影響後世近二百年音樂發展的重要作品。
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.
