Nocturnal op. 70 is one of the most important large-scale works written for guitar in the twentieth century. Brief biographical data and some background information on Nocturnal show how it exemplifies Britten's compositional approach. The focus of the analysis is on three structural aspects: the rhythmic, the intervallic, and the aspect of underlying pitch patterns. The rhythmic analysis discusses the distortion of rhythmic patterns by the use of compression, expansion, elisions, syncopation, and rhythmic dissonance. The pitch set analysis discusses the intervallic character of the work, identifying and correlating set types as they form networks of relationship. The reductive analysis discusses the underlying connections of focal pitches in the linear material of Nocturnal. The conclusion then correlates the results of the preceding analyses, discussing the large-scale unfolding of the form in Nocturnal.

The purpose of this thesis is to provide translation of documents on lu from two primary sources for a study of the theory of ,lu, with the main focus on the interpretation and the signification attached to each of the twelve lu-pitch names. To establish the background information of the lu-10 system, an explanation of its acoustical properties is first presented. Based on the most important and widely used tonal system in ancient China -- the san-fen-sun-i system, the illustration is provided for the process of tone generation. Methods proposed by the main theorists who engaged in the discussion of the system of lu are presented. The introduction of the concept of yin and yang in reference to the twelve lu and the signification of the lu-lu system in relation to the human and natural world will also be discussed. The main body of this study is devoted to the translation of written references on the meaning of the twelve lu. The first part is the translation of the selected passages from The Anthology of the Historical Document of Ancient Chinese Music. edited by Tsai-Ping Liang; the second part is the translation of a modern exegesis from an article written …
