Three original software programs utilizing improvisation and live sampling are presented here, along with a discussion of aesthetic issues raised by each. They are entitled Zur Elektrodynamik bewegter Musiker, Motet, and Gamepad Sampler. These programs vary in the degree of required interaction and in the kind of user control. They are each studies in imitative counterpoint through live sampling, with an approach seeking elegance before solutions. Because of the improvisational nature of these works, there is no standard musical score. Instead the complete Max/MSP source code and a sound recording of performances making use of these programs in varied situations are included. A discussion of issues raised by these works includes aesthetics, ontology, performance, and the role of the composer. Non-interactive indeterminate compositions are ontologically thin, because some composerly agency is required of the performer. An interactive work can be ontologically substantial if it makes distinct and significant contributions to performance, even though it may not make sound on its own. Although reproducibility reduces ontology and eliminates aura, live sampling within a performance can deepen the ontology of the performance by recontextualizing previous events, reframing the original event as the first reference to an abstract musical idea that lies outside …

Charlotte Moorman (1933–1991) was a Juilliard-trained cellist whose life and work made an indelible mark on the development of the American avant-garde. In her career, Moorman acted as a performer, collaborator, composer, administrator and muse. She solely founded the inaugural New York Avant Garde Festival, and subsequently directed fifteen of these festivals between 1963 and 1980, the feat for which she is most widely acknowledged today. Yet, her revolutionary performance practice, which blurred the lines between her life, her body, and her work, and brought into focus the dynamics of corporeality, the feminine body, female nudity and sexuality, and gendered politics within the contexts of musical performance, has so far escaped serious consideration in the written histories of the American avant-garde. This dissertation describes the nature of Moorman's practice as one that evolved to become inherently and irrevocably embodied, explores how this approach fell at odds with the pervasive avant-garde philosophies of music, and illustrates how her work troubles even a feminist musicological analysis. Further, through a contemporary critique of Moorman's oeuvre which centralizes the social, cultural, and political implications of her body in performance as integral to the work, this project offers a retrospective visibility to the artist which …

This dissertation investigates how W. A. Mozart applies the concept of key characteristics—the affective properties of each tonality—as discussed by three of his contemporaries, Johann Mattheson, C.F.D. Schubart and G.J. Vogler, to four soubrette and four prima donna characters from four of his late Italian operas: La Contessa and Susanna in Le nozze di Figaro; Donna Anna and Zerlina in Don Giovanni; Fiordiligi and Despina in Così fan tutte; Vitellia and Servilia in La clemenza di Tito. The analytical method of this dissertation provides a hermeneutical tool to search for meanings in Mozart's music. The application compares the libretto text and its corresponding tonal center with the description of key characteristics on a micro level, to reveal significant dramatic and practical implications from Mozart's key usage in his operas.

In 2003, Jan Bach completed his monumental Concerto for Tuba and Chamber Orchestra. This concerto requires unique performance techniques and technical skills unlike the majority of available tuba repertoire. In addition to these techniques, the guide explores the influence of popular songs, jazz/rock/funk styles, implied humor, and personal experience through an interview with the composer.

The Concerto for Trumpet and Orchestra and the Sonata for Trumpet and Piano by Karl Pilss were written in 1934 and 1935, respectively. They are examples for solo trumpet of the late German Romantic style of melody, harmony, form and structure. Musicians and audience often overlook composer Karl Pilss outside his native Vienna. His ties to the Trompeterchor der Stadt Wien and the National Socialist Party during the years preceding the Second World War have limited widespread acceptance of this composer. Pilss' output includes concertos for trumpet, horn, bass trombone, and piano, sonatas for trumpet, violin, and oboe, wind quintets and octets, piano pieces, choral works, and numerous large and small brass works. Pilss' teacher Franz Schmidt is more widely known. His four symphonies provide examples of post-Romanticism at the beginning of the twentieth century. His characteristic use of melody, harmony, form and structure is in the mold of Richard Strauss. Schmidt did not write any works for solo trumpet. However, his Symphony No. 4 begins and ends with extended passages for solo trumpet. Pilss inherited and adopted many of Schmidt's melodic, harmonic and formal traits. These can be clearly heard in his Concerto for Trumpet and Orchestra and the …
