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.

Sechs streichen und sieben ist eine Komplementär-Komposition zu Ittidra von Iannis Xenakis unter Verwendung seiner Kompositionstechnik des „Siebens“. Ein „Sieb“ wird bei Xenakis auf das Klangkontinuum gelegt, so dass nur bestimmte Töne erscheinen können. In das Stück ist ein Zitat von Xenakis zum Begriff der „Schönheit“ in der Kunst eingeflossen. Die Komposition entstand im Kontext des Projektes „Xenakis – RevierWechsel“ anlässlich des 100. Geburtstages von Iannis Xenakis im Jahr 2022 und wurde in Leipzig vom Ensemble El Perro Andaluz uraufgeführt.

Das überschaubare Cembalowerk von Iannis Xenakis ist aus musikanalytischer Perspektive ergiebig. Gerade sein erstes (Khoaï, 1976) und letztes (Oophaa, 1989) Werk für Cembalo zeigen auf, wie unterschiedlich er mit dem performativen Aspekt seiner Musik kompositorisch umgegangen ist. Während in Khoaï zahlreiche Überlegungen zur Spielbarkeit mit einflossen, was gerade anhand der Stellen, die Xenakis aus seinen beiden Klavierwerken Erikhthon (1974) und Evryali (1973) übertrug, deutlich wird, konzentrierte er sich bei Oophaa eher auf das dem Werk zugrundeliegende Konstruktionsprinzip und die architektonische Struktur des Werks, was in unspielbaren Stellen resultierte. Der Beitrag zeigt diese dem Werk Xenakis’ inhärente Dichotomie analytisch auf und untersucht aufgrund dessen zwei interpretatorische Lösungsvorschläge für Oophaa. Der Aspekt der Spielbarkeit bzw. Performance-Überlegungen auf Seiten des Komponisten werden somit als einen die Analyse mitbestimmenden Parameter ernst genommen. / The small harpsichord oeuvre of Iannis Xenakis yields a great deal of insight from a musicanalytical perspective. Especially his first (Khoaï, 1976) and last (Oophaa, 1989) works for harpsichord show how differently he dealt with the performative aspects. Whereas in Khoaï, numerous considerations regarding playability were incorporated, which becomes particularly evident in the passages that Xenakis transferred from his two piano works Erikhthon (1974) and Evryali (1973), in Oophaa, he concentrated more on the underlying construction principle and the architectural structure of the work, which resulted in unplayable passages. This contribution analytically demonstrates this dichotomy inherent in Xenakis’ work and, based on this, examines two proposed performative solutions for Oophaa. Thus, the aspect of playability, or performance considerations on the part of the composer, are taken seriously as a parameter contributing to the analysis.

The first part presents the programs and the program notes of the concerts held on August 23, 2013 and April 25, 2014. The second part presents the paper, which aims to study the use of multiple percussion in Iannis Xenakis solo and mixed chamber music, identifying and discussing performance characteristics of this set of works as well as idiosyncratic elements of percussion written by this composer. The paper begins with the concept of multiple percussion, historically situates the percussion in Western classical music during the twentieth and twenty-first centuries, and underscores the importance of Iannis Xenakis as a composer for this new lineage of percussion. The paper also proposes an approach to the works in which there is one percussionist playing multiple percussion set-ups, in solo or mixed chamber music context. Thus, the selected works are: Psappha (1975), Dmaathen (1976), Komboï (1981), Kassandra (1987), Oophaa (1989), Rebonds (1987/89) and Plektó (1993). After delimiting the repertoire to be studied, this paper identifies and discusses four characteristics of the works: (1) instrumentation, (2) the use of polyrhythms, (3) issues relating to the impossibilities in Xenakis’ music and (4) the use of polyphonic textures. The discussion section suggests traits that characterize the composer’s writing, identifying elements of recurrent use in various works, developing benchmarks, proposing technical solutions and developing interpretive conceptions that seek to contribute in the preparation of the performance of this set of works. / Esta pesquisa está organizada em duas partes: A – Produção artística e B – Artigo. A primeira parte apresenta os programas e as notas de programa dos concertos de qualificação e defesa, realizados, respectivamente, nos dias 23 de agosto de 2013 e 25 de abril de 2014. A segunda parte consiste no artigo, que tem como principal objetivo estudar a utilização da percussão múltipla em obras solo e de câmara mista de Iannis Xenakis, identificando e discutindo particularidades da performance desse conjunto de obras, bem como elementos idiossincráticos na escrita percussiva do compositor. O artigo parte da conceituação de percussão múltipla, situando historicamente a percussão na música clássica ocidental durante os séculos XX e XXI, e ressalta a importância de Iannis Xenakis como compositor para essa nova linhagem do fazer percussivo. O trabalho também propõe dar um enfoque nas obras em que há um percussionista tocando percussão múltipla, seja solo ou em um contexto camerístico misto. Assim, as obras selecionadas e discutidas ao longo deste artigo são: Psappha (1975), Dmaathen (1976), Komboï (1981), Kassandra (1987), Oophaa (1989), Rebonds (1987/89) e Plektó (1993). Delimitado o repertório a ser estudado, este artigo identifica e discute quatro particularidades das obras: (1) instrumentação, (2) uso de polirritmias, (3) questões referentes a impossibilidades na música de Xenakis, e (4) uso de texturas polifônicas. A discussão aponta traços que caracterizam a escrita do compositor, identificando elementos de uso recorrente nas diversas obras, elaborando pontos referenciais, propondo soluções técnicas e desenvolvendo conceitos interpretativos que buscam contribuir para a preparação da performance do conjunto de obras.

PhDr. Jaroslav Bláha, Ph.D. Abstract The thesis deals with a comparative analysis of a project called Poéme électronique in the Philips Pavilion (1958), while an emphasis is put on its mathematical background and broader interdisciplinal contexts. Particular attention is devoted to grand oldman Iannis Xenakis. The thesis tries to interpret the phenomenon of Electronic poetry, which we understand as an effort to design a multimedia "Gesamtkunstwerk". This brings the necessitate of the multi-specialized synthetic approach in searching of a relationship between the kinds of arts, and the analysis of interactions of individual project components.
