Thesis (MMus (Music))--University of Stellenbosch, 2009. / The relationship between music and mathematics has been subjected to debate for centuries. There are two schools of thought with the one viewpoint holding that the relationship between mathematics, which is conceived as an abstract and cold discipline, compared to music, which is rich with emotion, must be very limited. Arguments for this view draws, for example, on recent research which indicates that musical talent is not inherently linked to mathematical capability. On the other pole of the debate is the belief that although music and mathematics contribute to different parts of society, there is a very important inter-relationship between the two fields. Of great interest to the latter is the Greek composer Iannis Xenakis whose musical aesthetics incorporates this philosophy. As composer, Xenakis used mathematical theories as basis for his musical works. He not only incorporated well known mathematical principles such as the Golden Section into his compositions but went further and, for instance, utilized Boolean Algebra, Probability theory and Stochastic processes in his music. His composition method based on these mathematical principles became known under the term Stochastic music and forms the focus of this thesis. The research project concentrates on the early part of Xenakis’ life in order to provide insight into the development of his composition methods. The mathematical principles at the centre of his stochastic compositions receive specific rationalisation. In doing so, the most significant probability distributions (Linear, Exponential, Poisson and Normal distribution) are defined in terms of their properties and Xenakis’ use of them. The application of these distributions is considered by looking at the early works Metastaseis (in which Xenakis confronted most of his musical problems and which formed the basis for his musical style) and Achorripsis (where he fully developed their implementation). An in-depth examination of the construction of Achorripsis is performed while scrutinizing Xenakis’ calculations. Specific attention is drawn to alterations and adjustments made to the calculations. His implementation of them into the final score is furthermore examined and it is shown where he deviated between the calculations and score. The thesis concludes by considering the extent and significance of the adjustments made by the composer in the name of artistic freedom.

This thesis focuses on the two selected works of the architect/engineer/composer Iannis Xenakis (1922-2001) / Philips Pavilion (1956-58) and Le Diatope (1978). It places these works at the intersection of architecture and music by showing how they combine spatial, musical and visual performances. Accordingly, it discusses them as exceptional twentieth-century examples of Gesamtkunstwerk / &ldquo / total work of art.&rdquo

<p>EVOLUTIONARY SKETCHES is a three-movement sextet composition for flute, clarinet in Bb, percussion, piano, viola, and cello. The idea of the piece is based on the study of applying scientific evolutionary theories to compositional techniques. The first movement reflects my attempt to realize the generic process of development from one generation to the next by natural selection, crossover, or mutation. In the second movement, I conceive an image of evolution in which changes take place through battles among different evolutionary factors over progress. The structure of the third movement explores the extensive use of cellular automata.</p> / Dissertation

Inicialmente, o fenômeno sonoro é analisado dentro de suas três dimensões – altura (freqüência), intensidade (pressão sonora) e tempo (duração) – considerando as pesquisas de Pierre Schaeffer e Abraham Moles. Segue-se a este tema uma análise especifica sobre a dimensão do tempo. A fim de construir uma visão abrangente sobre as acepções deste conceito, propomos uma divisão entre tempo objetivo (visão dos filósofos da Grécia Antiga) e tempo subjetivo (visão de Santo Agostinho e Kant). Ademais, são detalhadas as acepções sobre o tempo propostas por Husserl, Bergson e Bachelard. Sempre que possível, articulamos o pensamento de Xenakis aos conceitos apresentados. A partir deste referencial teórico, realizamos uma análise de três obras de Xenakis: Metastaseis (1953 – 54), Concret PH (1958) e Bohor (1962), retomando as categorias temporais definidas por ele, além de abordar seu método composicional implementado nos anos 1950, a música estocástica. Seu trabalho composicional tem como principais características multidisciplinaridade (sua obra musical abarca conceitos arquitetônicos, filosóficos e científicos) e a indissociação dos conceitos de tempo e espaço, formando um esquema no qual os eventos musicais são justapostos ou sobrepostos. Em anexo a este trabalho, apresentamos quatro composições nas quais o tempo musical foi refletido e trabalhado a partir do referencial teórico adquirido durante esta pesquisa / This work intends to investigate and analyze the temporal dimension of the sound, departing from the temporal categories proposed by Iannis Xenakis: outside-time, in-time and temporal. Initially, the sound phenomenon is analyzed in its three dimensions – pitch (frequency), intensity (sound pressure) and time (duration) – considering the investigations of Pierre Schaeffer and Abraham Moles. Following to this topic, a specific analysis of the dimension of time is presented. In order to elaborate a comprehensive view about the meanings of this concept, a division between objective time (ancient Greek philosophers’ view) and subjective time (Saint Augustine and Kant’s view) is proposed. Moreover, significations of time by Husserl, Bergson and Bachelard are detailed. Whenever possible, Xenakis’ thought is linked with the presented ideas. From this theoretical reference, three works of Xenakis are analyzed: Metastaseis (1953 – 54), Concret PH (1958) and Bohor (1962), recovering the temporal categories defined by him, and also addressing his compositional method implemented during the 1950’s: stochastic music. His compositional work is characterized by multidisciplinarity (his musical work comprehend architectural, philosophical and scientific concepts) and by the indissociation of time and space concepts, conceiving a model in which musical events are juxtaposed or superposed. Attached to this work, four compositions are presented, in which musical time is thought and manipulated regarding the theoretical references acquired during this research

Cette thèse explore les rapports entre la formalisation mathématique, ses implications dans les pratiques compositionnelles et ses répercussions sur l’interprétation analytique. Elle se base sur l’étude de Semi-Simple Variations pour piano (1956) de Milton Babbitt, de Nomos Alpha pour violoncelle (1965-1966) de Iannis Xenakis (1921/22-2001), et d’une sélection de textes théoriques publiés par les compositeurs autour de ces deux œuvres.L’argumentaire est divisé en trois parties. La première étudie les textes théoriques afin d’en dégager les éléments formalisés (ou résultant de la formalisation) ainsi que les indices permettant d’en retracer les implications dans les pratiques compositionnelles. Ces éléments sont précisés dans la deuxième partie via la reconstitution des traces laissées par les composantes formalisées dans les textes musicaux (« modèles théoriques »). Ce travail est mené sur les deux œuvres proposées à l’analyse puis élargi à d’autres œuvres. Les modèles théoriques de deux d’entre elles étaient jusque-là restés inédits : Three Compositions for Piano de Babbitt (1947-1948) ; et Akrata de Xenakis pour 16 vents (1964-1965). La troisième partie soumet Semi-Simple Variations et Nomos Alpha à deux analyses : la première étudie les modèles théoriques, directement liés aux univers formels, alors que la seconde examine les surfaces sonores et comment elles articulent et/ou contredisent les éléments dégagés au niveau des modèles. Tout en soulignant le rôle fondamental, quoique très différent, joué par la formalisation dans les univers compositionnels de Babbitt et de Xenakis, la distance séparant les modèles théoriques des surfaces sonores amènent à considérer l’apport des premiers dans l’interprétation analytique comme étant de nature avant tout heuristique. En tant que traces de la pensée du compositeur, les modèles théoriques peuvent néanmoins suggérer de nouvelles pistes et méritent d’être intégrés à des recherches futures. / This thesis explores the links between mathematical formalization, its implications in compositional practices, and its repercussions on the analytical interpretation. It is based on the study of Milton Babbitt’s Semi-Simple Variations for piano (1956), on Iannis Xenakis’ Nomos Alpha for violoncello (1965-1966), and on a selection of theoretical texts published by the composers around these two works. The argumentation is divided in three parts. The first studies the theoretical texts with the aim of extracting from them the components that are formalized (or result form formalization) as well as the indices pointing towards their implications in the compositional practices. These are then put into sharper view in the second part, through the reconstruction of the traces left by these components in the musical texts (“theoretical models”). This reconstruction is first conducted on the two main works considered before other works are considered. The theoretical models of two of them had until now remained unknown: Three Compositions for Piano by Babbitt (1947-1948) ; and Akrata for 16 winds (1964-1965) by Xenakis. The third part submits Semi-Simple Variations and Nomos Alpha to two analyses: one is aimed at the theoretical models, directly linked to the formal universes, the second examines the musical surfaces and at the way they articulate and/or contradict the elements observed in the models. While underlining the fundamental - though very different - role played by mathematical formalization in Babbitt’s and Xenakis’ compositional universes, the distance that separates the theoretical models from the musical surfaces brings one to consider the role of the former within the analytical enterprise as essentially heuristic. As traces of the composer’s thinking, the theoretical models may however suggest new approaches and deserve to be fully integrated in future research.

In the essay A Rhetorical Guide to Ebb I explore the diverse array of influences in art, and music that guided the creation of the composition Ebb, for 13 musicians and electronics. Of those influences, the boxes of the American artist Joseph Cornell played a particularly important role. Having based the conceptual framework for Ebb on ideas taken from Cornell, the essay, instead of being driven by a single thesis, involves the creation of conceptual boxes. These conceptual boxes emphasize the influence of the artist Joseph Cornell, along with the composers Iannis Xenakis and Gérard Grisey. In addition, a time line documenting the stages in Ebb's creation is included.
