Isang Yun (1917-1995), one of the most important avant-garde German-Korean composers, is perhaps best known for his success at integrating Korean musical elements into traditional Western styles. His Concerto for Oboe, Oboe d'amore, and Orchestra incorporates many traditional Korean elements, and uses techniques such as Hauptton, Hauptklang, and Umspielung to blend these elements into a Western musical style. This study explores the elements of traditional Korean music and instruments present in Yun's score, examines his compositional techniques, and makes practical performance suggestions that allow performers to properly convey his intentions. This dissertation includes six chapters. The first chapter discusses the purpose and importance of the study. The second chapter reviews Isang Yun's biography and works, based on a published interview with Yun and a biography written by his wife of many years. The third chapter introduces the characteristics of traditional Korean woodwind instruments relevant to the work. The fourth chapter examines Yun's compositional techniques of Hauptton, Hauptklang, and Umspielung in the work and their relationship with the main-tone and Sigimsae techniques. The fifth chapter introduces and explores different types of Sigimsae in the work, with suggestions for quarter-tone performance techniques. The sixth and last chapter is a conclusion.

The first Western opera to be performed in Korea was Verdi's La Traviata on January 16, 1948, by the Joseon Opera Company. The first Korean opera, Chunhyangjeon by Jae Myung Hyun, premiered at the Korean National Theater in May 1950, just before the outbreak of the Korean War. Daejeon.go.kr reports that since that year approximately 200 Korean operas have been produced in Korea. Nevertheless, there have been consistent efforts to create and introduce Korean operas to the public. Most of them ended up being "one-off" performances with a single production. Most research on Korean opera has focused on its history, the challenges of producing new operas, or an analysis of selected Korean operas. This study equips singers with the following: pertinent historical background with the libretto, a synopsis, research regarding the composer and librettist, a character analysis, vocal and textual analysis of the selected opera arias, instruction regarding the Korean language, IPA, and a word-by-word translation of the text. I also make recommendations for tenor arias from Korean operas for singers with specific voice types.
