Ce mémoire traite de l'acoustique de la clarinette et du rôle de l'anche, résumant des travaux menés entre 2001 et 2018 sur divers sujets :I) Étude de modèles analytiques élémentaire focalisée sur : 1) le rôle des pertes. 2) les cartes itérées, mettant en évidence divers régimes de fonctionnement, utiles aussi pour la pédagogie instrumentale. II) Étude de caractérisation des anches : 1) Étude dynamique des résonances de l'anche réalisée par holographie. Elle conduit à un modèle de matériau viscoélastique expliquant certaines différences observées dans les fréquences des 15 premiers modes de l'anche. 2) Étude statique des caractéristiques mécaniques et aérauliques de l'excitateur (anche+bec+lèvre). La méthode mesure précisément la quantité d'air entrant dans l'instrument en fonction de la pression de lèvre et d'air. III) Synthèse sonore par modèle physique en temps réel : 1) Modélisation mécanique et aéraulique de l'anche, d'après mesure. Le modèle de ressort raidissant non linéaire proposé autorise une simulation dynamique efficace. 2) Estimation modale de l'impédance d'entrée (mesurée) des instruments à vent. On montre les techniques de conception de filtres numériques précis et passifs à toute fréquence. 3) Modélisation et simulation instruments à vent au moyen de guide-ondes, par estimation modale, implémentée dans un logiciel en C++. IV) Une étude de jouabilité d'un panel de 40 anches par analyse canonique des corrélations révèle des liens statistiquement solides entre mesures physiques, évaluations subjectives et synthèse sonore. Elle autorise une caractérisation des anches pouvant être réalisé par le fabricant, selon au moins 4 facteurs indépendants. / This thesis deals with the acoustics of the clarinet and the role of the reed, summarizing studies carried out between 2001 and 2018 on various topics : I) Study of elementary analytical models, focused on 1) role of losses. 2) iterated maps, highlighting various operating regimes, which are also useful for the instrumental pedagogy. II) Reed characterization study : 1) Dynamic study of the reed resonances, by holography. It leads to a model of viscoelastic material explaining some differences observed in the frequencies of the first 15 modes of the reed. 2) Static study of the mechanical and aeraulic characteristics of the exciter (reed + mouthpiece + lip). The method accurately measures the airflow entering the instrument as a function of lip and air pressure. III) Sound synthesis by physical model in real time : 1) Mechanical and aeraulic modeling of the reed, according to measurements. The proposed nonlinear stiffening spring model allows for an efficient dynamic simulation. 2) Modal estimation of the (measured) input impedance of wind instruments. Design techniques for accurate digital filters, passive at any frequency, are described. 3) Modal estimation and simulation of wind instruments by waveguides, implemented in C ++ software. IV) A playability study of a panel of 40 reeds by canonical correlation analysis reveals statistically strong links between physical measurements, subjective evaluations and sound synthesis. It allows a characterization of the reeds that can be made by the manufacturer, according to at least 4 independent factors.

Max Reger was a prolific composer on the threshold of modernism. The style of his extensive musical output was polarizing among his contemporaries. A criticism of Reger's music is its complex and dense musical structure. Despite writing tonal music, Reger often pushes the boundaries of tonality so far that all sense of formal organization is seemingly imperceptible. In this dissertation, I offer what I observed to be a new way of discerning Reger's motivic relationships and formal structures within and between movements. There are three primary tools and methods I incorporated to make these observations: Schoenberg's developing variation; melodic contour analysis as discussed by Elizabeth West-Marvin and Diana Deutsch; and Janet Schmalfeldt's motivic cyclicism stemming from internal themes. In this dissertation I examine five different musical works by Reger: D minor Piano Quartet, Clarinet Quintet, Piano Concerto, String Quartet, op. 121 and E minor Piano Trio, op. 102. My analysis shows how Reger relies on melodic contours of his motives to connect musical moments across entire movements and entire works with multiple movements. These motives are developed and often mark structurally significant moments providing the organization often perceived as missing in Reger's music.

Among the Voices Voiceless is a composition for flute (doubling piccolo), clarinet (doubling bass clarinet), viola, cello, percussion, piano, and electronics, based on the poem "What would I do without this world faceless incurious" by Samuel Beckett. The piece is a setting for disembodied voice: the vocal part exists solely in the electronics. Having no physical body, the voice is obscured as the point of empathy for the audience. In addition, instrumental solos compete for focus during the work's twenty minute duration. In passages including a soloist, the soloist functions simultaneously as antagonist and avatar to the disembodied voice. Spoken word recordings and electronic manipulation of instrumental material provides further layers of ambiguity. The companion critical essay "Among the Voices Voiceless": Setting the Words of Samuel Beckett proposes the distillation of Beckett's style into the elements of prosaicness, repetition, fragmentation, ambiguity, and symmetry. Discussions of Beckett's works such as Waiting for Godot and Molloy demonstrate these elements in his practice. This framework informs the examination of two other musical settings of Beckett's poetry: Neither by Morton Feldman and Odyssey by Roger Reynolds. Finally, these elements are used to analyze and elucidate the compositional decisions made in Among the Voices Voiceless.

The career of Osvaldo Lacerda (1927-2011) spanned a critical time in the development of Brazilian nationalist music. Though he was an outspoken nationalist composer, he was also influenced by European trends and training. Even within his nationalist compositions, evidence of a shift in style that mirrors the European movements of Modernism and Postmodernism is found in his works. Among his thirty-six chamber works, three are wind quintets, written between 1962 and 1997. Although all three works warrant extended discussion, Variações e Fuga para quinteto de sopros is particularly valuable for studying Lacerda's musical language. It was originally written in 1962. However, Lacerda made significant revisions in 1994, completely rewriting and expanding it. Through comparing the 1962 and 1994 versions of Variações e Fuga and analyzing the significant differences between the two, this document aims show that even with his strong stance as a Brazilian nationalist composer, Lacerda was clearly influenced by the movements of the broader music world. Examples from his other two woodwind quintets, Quinteto de sopro and Suíte pra cinco, written in 1988 and 1997 respectively, help to support the idea that this change in his musical language was not an anomaly, but rather a true evolution of style impacted by his own culture and that of the classical music world around him.

The purpose of this study is to explore the literature for textless voice and woodwind instruments. The primary focus concerns the timbral and ensemble possibilities exploited in three twentieth-century works in which the voice is treated as an instrument i.e., without the usual preoccupation with textual meaning. An historical overview of vocal works with obbligato woodwinds and concerted works for textless voice serves as an introductory chapter. The variables of voice and instrument acoustical makeup, vocal vowel formation and instrumental voicings, volume, vibrato, resultant tones, range, and extended techniques (fluttertongue, special vibrato demands, non-vibrato, etc.) are the focus of the performance considerations for this study. Over thirty twentieth-century textless works for voice and at least one woodwind instrument were located. The three, chosen for this study represent different periods in the century, and present contrasting styles and musical merit: Aria (1931) by Jacques Ibert, Three Vocalises (1958) by Ralph Vaughan Williams, and Duos I (1976) by Nancy Chance. A style and performance analysis of these works with pertinent research on the composers is presented. Appendices include an annotated bibliography of selected works for the medium, a written interview with Nancy Chance, and performance notes provided by the composer, concerning Duos I.

Younghi Pagh-Paan is an internationally renowned contemporary Korean-German composer. While her music has been strongly influenced by German contemporary musical aesthetics, her compositions also possess Korean musical and cultural influences. In her works, Pagh-Paan employs Western instruments and musical languages that incorporate contemporary techniques such as vibratos, flatter tonguing, pitch bends, and legato glissandi. These effects are thought to imitate the sounds created by traditional Korean instruments. Man-Nam I, for clarinet and string trio, was the second work that Pagh-Paan composed following her move from Korea to Germany. The piece includes many sounds representative of traditional Korean instruments, along with significant symbolism of the sociological background, culture and history of Korean people. The study of Man-Nam I focuses on unraveling hidden elements of Korean traditional music and culture, and addresses the need for the performers to understand its rich Korean influences in order to reach a deeper interpretation of Pagh-Paan's work.

Det här arbetet diskuterar ett utforskande musikaliskt gestaltningsprojekt, Från botten av en brunn, som utgörs av fyra satser för klarinett, cello och modulärt synthesizersystem baserat på var sin person ur den japanska författaren Haruki Murakamis roman Kafka på stranden (Umibe no Kafuka, 海辺のカフカ) från 2002. Arbetet har utgått ifrån en metodisk bearbetning av romantexten med hjälp av grundad teori för att skapa både syntetiska och samplade klanger och komposition ur texten. Grundad teori togs ursprungligen fram inom sociologi för att forma ny kunskap ur kvalitativ data med hjälp av en rigorös process, där teoretisk känslighet stödjer och vägleder tolkningar. I mitt arbete har det här snarare handlat om estetisk sensibilitet som väglett mina tolkningar av texten, hjälpt mig att göra urval och omforma romanen till musik och framförande. / This work discusses an exploratory musical composition project, From the bottom of a Well, which consists of four movements for clarinet, cello, and modular synthesizer system, where each movement is based on each person from the Japanese author Haruki Murakami's novel Kafka on the beach (Umibe no Kafuka, 海辺のカフカ) from 2002. The work has been based on a methodical processing of the novel text with the help of grounded theory to create both synthetic and sampled sounds and composition from the text. Grounded theory was originally developed in sociology to shape new knowledge from qualitative data using a rigorous process, where theoretical sensitivity supports and guides interpretations. In my work, this has rather been about aesthetic sensibility that has guided my interpretations of the text, helped me to make selections, and to transform the novel into a music composition and a performance.

This document focuses on background and performance practice of various musical styles encountered in Paquito D'Rivera's The Cape Cod Files. More specifically, the musical styles examined include: boogie-woogie, Argentine milonga, classical and popular Cuban music, American twelve-bar blues, contemporary atonal music, and Cuban danzón. A brief biography of Paquito D'Rivera is included to establish context of the composer's musical background. Each chapter examines one of the four movements and the musical styles found within that movement. A brief history of each musical style is provided to inform appropriate performance practice decisions.
