Karlheinz Stockhausen’s Kathinkas Gesang als Luzifers Requiem presents mental, physical, and musical challenges that go beyond the usual expectations of an instrumentalist, extending and redefining the traditional idea of virtuosity. Using firsthand performance experience, score and recording study, and flutist interviews, this document explores the effects of some of these heightened demands and argues that the particular performance situation presented by Kathinkas Gesang brings up critical questions about the performer’s role, the nature of performance and of the musical work, and the existence of an authoritatively “authentic” interpretation. Employing an expanded definition of virtuosity that includes interpretation and encompasses both choices and actions, the document discusses the extensions of virtuosity into two main areas: first, memory; and second, staging and movement, covering both practical suggestions and larger implications. Finally, it examines how the performer’s negotiation of these challenges relates to questions about authenticity and agency. Performance is defined here as a creative and collaborative act, not attempting to duplicate previous performances or recordings, but rather to give the best realization of the piece possible in the given circumstances, according to the individual’s interpretation of the score’s directions. There is no single “authentic” interpretation, but rather a rich multiplicity of possibilities, …

This dissertation focuses on three of Busoni’s late orchestral works known as “orchestral elegies”: Berceuse élégiaque (Elegie no. 1, 1909), Gesang vom Reigen der Geister (Elegie no. 4, 1915), and Sarabande (Elegie no. 5, 1918-19). The study seeks to provide a better understanding of Busoni’s late style as a crucial bridge from late nineteenth-century chromaticism in the works of Liszt, Wagner, and others to the post-tonal languages of the twentieth century. At the heart of this study lies a particular concept that forms the basis of many characteristic features of Busoni’s late style, namely the concept of polyphonic harmony, or harmony as a cumulative result of independent melodic lines. This concept is also related to a technique of orchestration in which the collective harmony is sounded in such a way that the individual voices are distinct. In the highly personal tonal language of Busoni’s late works, passages often consist of a web of motives weaved throughout the voices at the surface level of the music. Linear analysis provides a means of unravelling the dense fabric of voices and illustrating the underlying harmonic progressions, which most often consist of parallel, primarily semitonal, progressions of tertian sonorities. Chapter 1 provides a backdrop …

Pedagogical methods in piano instruction are constantly evolving. Traditional approaches for beginning students typically focus on teaching music theory and developing the skills necessary to read music. Some contemporary methods, however, are centered on training students to use their whole body while playing the instrument. These more recent methodologies allow students to bond with the piano in a more personal manner, as if they were playing a game with a big toy. One of the most representative works of this approach is the eight-volume collection Játékok (1973) by György Kurtág (b.1926). Volume 1 of Játékok consists of short pieces featuring a new graphic notation devised by Kurtág himself. It also incorporates the use of unusual piano techniques, such as playing with the palm, fist, and forearm. The method also explores the use of the entire range of the instrument. Though the work is over 40 years old, Játékok is only infrequently used as a teaching tool for piano instructors in Hungary, and is unknown in the United States. This probably stems from the fact that it presents students and teachers with atypical musical elements such as unusual notation, use of an unlimited register, and pieces that feature varying degrees of …
