Chen Yi's music is well accepted and recognized nationally and internationally through an increasing number of commissions and performances. Major symphony orchestras, choruses, institutions and companies request her compositions on many occasions in order to increase understanding and exploration of Chinese influences on western classical idioms. This study provides the first detailed discussion of her compositional mastery and her fusion of Chinese music with the language of western choral traditions. Chen Yi's reputation as a prominent orchestral composer does not restrain her passion to apply instrumental techniques and materials to her quality choral compositions. This study focuses on (1) how hardship and various life experiences during the ten-year Cultural Revolution shaped Chen Yi's musical inspirations; (2) how the influences of major musical genres, such as traditional Chinese folksong, jingju, model play, 19th-20th century nationalism, impressionism, and serialism are consolidated in her kaleidoscopic compositional techniques; and (3) the application of Chinese languages, pedagogical concepts, and extra-musical elements, such as Chinese poems, paintings, and calligraphies, revealed in her original, intelligent and resourceful choral creations.

abstract: ABSTRACT The purpose of this study is to analyze Tunes from My Home, a Trio for Violin, Cello, and Piano by Chinese-American composer Chen Yi (b. 1953), as well as to provide a performance guide from a collaborative pianist's perspective. Of Cantonese origin herself, Chen Yi composed several works inspired by Cantonese music, including this trio. Chen Yi composed this trio between 2007 and 2008 and dedicated it to her long time friend pianist Pan Xun, who is also of Cantonese origin. Inspired by this shared Cantonese heritage, Chen Yi incorporated within this work three well-known Cantonese tunes, Cantonese instrumental techniques and sonorities, and elements of the shifan luogu, a wind and percussion ensemble often used in traditional Cantonese music. Coming from the same region as the composer, the author of this paper feels connected with this piece, and as a collaborative pianist, has the opportunity to introduce Cantonese music to a wider audience through the piano trio. Chapter one introduces the motivation for this study. Chapter two provides a brief biography of Chen Yi. Chapter three introduces the history, the scales, and the instruments of Cantonese music as well as other Cantonese influences on this trio, especially the three tunes. Chapter four includes a detailed analysis of each movement in terms of the form and application of the tunes and rhythms of Cantonese music. Chapter five shares the author’s experience of approaching and interpreting this piece in an appropriate style based on her Cantonese roots. The conclusion evaluates the significance of the fusion of Cantonese music with Western compositional techniques in this piece. / Dissertation/Thesis / Doctoral Dissertation Music 2017

abstract: This dissertation focuses on seven solo piano works written by contemporary Chinese-American composer Chen Yi. It is presented in the form of a recording project, with a written analysis of each recorded composition. The seven recorded pieces are Variations on "Awariguli", Duo Ye, Guessing, Two Chinese bagatelles: Yu Diao and Small Beijing Gong, Ba Ban, Singing in the Mountain, and Ji-Dong-Nuo. They were written between 1978 and 2005, presenting a wide range of Chen Yi's compositional style. The written portion consists of five chapters. After the introductory chapter, a sketch of Chen Yi's life is presented in Chapter Two. This chapter specifically uncovers Chen Yi's deep roots of Chinese traditional and folk music through her experiences during the Cultural Revolution. Chapter Three analyzes each of the seven pieces. Through formal structure realization, motivic analysis, and folk music implication, the author discovers the blend of Chinese and Western cultures throughout Chen Yi's music. Chapter Four discusses the performance aspect of these compositions through the author's recording experience. In this chapter, the author provides background information as well as suggestions on specific performance practice. The last chapter summarizes the entire dissertation. / Dissertation/Thesis / Variations on "Awariguli" / Duo Ye / Guessing / Two Chinese Bagatelles: Yu Diao / Two Chinese Bagatelles: Small Beijing Gong / Ba Ban / Singing in the Mountain / Ji-Dong-Nuo / D.M.A. Music 2012

abstract: In an interview with the author, composer Chen Yi shared thoughts regarding her inspiration to compose the piece As in a Dream. She composed the first version in 1988 for soprano, violin, and cello. Left unpublished, this work was re-done in 1994 with the Chinese instruments zheng and pipa in place of the violin and cello. As in a Dream is a setting of two linked poems of six lines each by Qingzhao Li, one of the earliest female poets in China. Chen Yi kept the voice part the same in the two versions, but adapted the accompaniment to suit the Chinese instruments. This study of As in a Dream focuses on the 1994 version, and especially on the first song, with a view to introducing the singer to its Chinese elements. To help performers to understand better the text of the set, a translation and transliteration of the two poems by Qingzhao Li are offered with line-by-line interpretation. An introduction to the history and characteristics of the zheng and the pipa is supported by examples of the uses of these instruments in the songs. Drawing upon information provided by Chen Yi in the interview with the author, a discussion follows of Mandarin speech tones and their effect on the melodic design of As in a Dream, with music examples. An examination of traditional Beijing Opera styles of singing, with insights provided by Rao Lan, the soprano for whom the work was written, leads to a description of the fusion vocal technique required for performance of As in a Dream and some of the rules for diction in Mandarin Chinese. Intended as an introductory guide for the soprano contemplating performance of Chen Yi’s As in a Dream, this study also reveals the combination of Eastern and Western musical characteristics in these songs and gives examples of how the music interprets the veiled meaning of the poetry. / Dissertation/Thesis / Doctoral Dissertation Music 2015

Since the founding of "New China" in 1949, the musical culture has undergone numerous periods of identity crisis, particularly during the ten-year "Cultural Revolution," due to the fact that music had always been used to serve the needs of political propaganda. Even the development of a "National Style" encouraged by the central government was a political "brainchild" under the socialist ideology. Nevertheless, professional musicians struggled to create a new path in musical composition while walking on the thin ice of harsh political climate. Isolated from the rest of the world for almost two decades, China's musical development had not been able to keep pace with the world until the late 1970s, when the central government reevaluated its agenda on how to lead the country. This change of political environment eventually led to a more open society. The newly established contact with the outside world in the musical scene lent great opportunities for Chinese musicians to study the newest thinking about music, which ultimately, in the early 1980s, fostered the emergence of a new "National Style"- the so-called "New Wave." The style of "New Wave" differs drastically from the earlier "National Style" in that it employs primarily twentieth-century compositional techniques in the course of processing nationalistic elements. Throughout the development of "New Wave," Chen Yi was one of the most avid proponents and leading figures.

近幾年，等候系統開始被廣泛的應用於分析工作上可能產生的延遲。 平均花費在系統中和等候線上的時間成為描述等候系統行為兩個最基本的數量。除了工作的延遲外，我們考慮顧客在等候線上的延遲也會受到滿意度的影響。由於顧客滿意度會影響顧客的到達率，因此系統到達率和系統服務率變成模糊集合。我們建構一個模糊的等候系統並且提出一個去模糊化的方法。這篇論文研究的目的在於呈現一個分析系統的方法，利用此方法解決模糊的系統中最佳化的問題。 關鍵字: 模糊等候，最佳化。 / Queueing models for analyzing the possible delay of tasks have been studied for past several decades. Since then, the average time spent in the system and the average time spent in queue have become two of the most fundamental quantities describing a queueing system's behavior. In additional to the delay of tasks, we consider the satisfaction of customers affected by several factors in system. Since the satisfaction reflects the arrival rate and service rate, the arrival rate and the service rate seem more close to the fuzzy sets. We construct a fuzzy queueing model and introduce an optimization problem of a fuzzy queue. The objective of this optimization problem is to present an approach that analyzes the model and decide the optimal number of servers while minimizing the total cost which is a fuzzy set. As a result, we provide a solution procedure to compute the required performance measure in a service-oriented environment. Keywords: Fuzzy Queue, Optimization
