In Chapters 1 and 2 there are definitions and a review of electroacoustic music, and then visualization generally and as applied to music. Chapter 3 is a review of specific and relevant literature as regards to the visualization of electroacoustic music. Chapter 4 introduces the concepts of imagining as opposed to discovering new sound, and what is important to this research about these terms; in addition what is meant and indicated by them. Chapter 5 deals with the responses that composers currently working have made to the enquiry concerning visualization. In this chapter these responses are dealt with as case studies. In a similar way, Chapter 6 looks at some examples of historical work in electroacoustic music, again as case studies. In Chapter 7 a taxonomical structure for the use of visualization in electroacoustic composition is established and derived from the case study results. Chapter 8 looks at relevant examples of software and how they offer visualization case studies. Chapter 9 looks at the place of the archive in various stages of the compositional process. Chapter 10 investigates the problems of visualizing musical timbre as possible evidence for future strategies. Chapter 11 offers some conclusions and implications as to the main research questions, as well as more specific outlines of potential strategies for the visualization of electroacoustic music.

White Dawn Streams is a composition for orchestra with tape. The orchestra includes woodwinds (flute, oboe, clarinet, bassoon), brass (horns(2), trumpets(2), trombone, tuba), percussion (timpani, bass drum, snare drum, tom-toms, timbales, temple blocks, suspended cymbal, triangle, xylophone), and strings. The tape was produced using a Synclavier digital synthesizer. The work consists of a single movement approximately eleven minutes in duration. The pitch materials in the work are derived from a single series of pitches and are used in a contrapuntal texture.

Perante a confirmação da incidência de influência oriunda do modelo contrapontístico sobre a concepção do modelo micropolifônico (MARTÍN, 2001; HOLLOWAY, 2004; HALSEY, 2012; FERRAZ, 2010; CLENDINNING, 1989; GRIFFITHS, 1983; BERNARD, 1994; RODRIGUES, 2008; STEINITZ, 2003), ficou latente a hipótese de que o modelo contrapontístico pudesse ser mais um elemento fundamental a esta desta confluência. Desta maneira, a presente tese visa investigar se o modelo micropolifônico consiste em uma tríplice confluência entre os modelos serial, eletrônico e contrapontístico - de maneira que estes três modelos sejam caracterizados enquanto indissociáveis perante o conceito de micropolifonia. A metodologia baseia-se fundamentalmente na análise das obras concluídas durante a fase micropolifônica de Ligeti (1957-1967), orientada sob a ótica da tríplice confluência aqui posposta. A investigação da hipótese aqui levantada, assim como de suas implicações e, consequentemente, da maneira como teria se dado esta reação, constam como objetivos fundamentais à presente pesquisa. / Abstract: "The triple historical-technical confluence in the concept of micropolyphony by György Ligeti (1957-1967): the conception of a hybrid technomorphic stylema" has as its starting point the discussions in "Historical-technical confluences in the concept of micropoliyphony (1956-1966)" (SOUZA, 2014). Due the confirmation of the influence of the counterpoint model on the conception of the micropoliphonic model (MARTÍN, 2001; HOLLOWAY, 2004; FERRAZ, 2010; CLENDINNING, 1989; GRIFFITHS, 1983; BERNARD, 1994; RODRIGUES, 2008; STEINITZ, 2003), it was hypothesized that the counterpoint model could be a fundamental element to this confluence. In this way, the present thesis aims to investigate wether the micropoliponic model consists of a triple confluence between the serial, electronic and counterpoint models - so that these three models are characterized as inseparable in the concept of micropolyphony. The methodology is based fundamentally on the analysis of the works completed during the Ligeti's micropolyphonic era (1957-1967), oriented under the perspective of this triple confluence. The investigation of the hypothesis as well as of its implications and consequently of the way in which this reaction would have occurred are presented as fundamental objectives to this research. / Doutor

這作品集共有三首作品：“謎語 I, 110806“ 為四個家居電話而作, “ 影。空“ 一首電子音樂作品, “交響詩“ 為管樂團而作 / 我嘗試在作品集當中運用一些以前我並不經常使用的作曲概念、作曲技巧，及配器法和一些樂器組合，以致我可以創作一些突破我以往風格的作品。以上三首作品都屬於不同類型，也有作不同的特質；樂曲順著創作日期先後而排列。我嘗試在 “謎語 I, 110806 和 “影。空 這兩首較早期的作品中實驗一下當時對我而言是創新的樂曲種類和作曲技巧。較近期的作品“交響詩是為管樂團而作。因為我學習圓號多年，所以這是我最熟悉的樂曲類型。 / “謎語 I, 110806“ / 這是一首為四個電話而作的實驗性作品，藉此表達出我們每天都在經歷充滿戲劇性的人生。電話可以產生出脈衝和音頻聲響，無疑是一件樂器。其實很多圍繞著我們的事物都可以用來創作音樂。我為這首樂曲的演出預先預備了一些錄音以在樂曲中特定的時間播出。演奏者可以按他們自己的喜惡以其他錄音代替。 / “影。空“ / 這是一首揉合電子合成器所產生的電子音效和真實錄音的電子音樂作品。創作靈感來自<聖經>的<傳道書>，我特別是被當中認為人生在世一切都如捕風捉影所觸動。我在音樂中使用了風聲作為一固定反復的樂句以貫穿全曲。有此作為一個無間斷的承托部分令到一些不可能在真實樂器演奏中發生的細緻音樂元素可以在這首樂曲中呈現。 / “交響詩“ / 這首樂曲的最大特點是我選擇在這首管樂團作品中運用了豎琴和馬林巴琴的二重奏。樂曲起始是一些精簡又有著強烈對比的樂段，這些樂段在樂曲較後部分融合一起，並發展成一長樂段。我在樂曲中主要著意於創造優美的旋律，當中蘊含著不規則的分句，卻不影響樂曲本身的流暢性。 / This portfolio consists of three pieces: Enigma I, 110806 for four domestic telephones, In Vain Like A Shadow an electronic piece, A Symphonic Poem for concert band / In my portfolio, I have attempted to use the compositional concepts and techniques, as well as orchestration and instrumentation method that were unfamiliar to me before, so as to ensure that I was writing works that would stretch beyond my usual musical tendencies. The three pieces in my portfolio all have distinctive styles and genres; each will be presented chronologically according to its completion date. In my two earlier pieces, Enigma I, 110806 and In Vain As A Shadow I wish to experiment with the genres and techniques that were new to me at the time. The most recent work, A Symphonic Poem, is composed for concert band. It is the genre that I am most comfortable and familiar with, owing to my years of training on the French horn. / Enigma I, 110806 / This is an experimental piece composed for four domestic telephones. This came out of my idea of creating a work that would enable music to express the drama we encounter in our daily lives. The telephone is no doubt a musical instrument--it can generate pulses and pitched tones. In fact, many objects that surround us can be used to create music. For the performance of this work in the past, I have prepared some pre-existing recorded sound tracks that can be played alongside at particular moments in time. However, those who wish to make their own sound tracks to substitute mine for the performance are welcome to do so. / In Vain As A Shadow / This is an electronic piece that combines recorded live sounds with effects that are produced by a synthesizer. While composing this work, I was inspired by the book Ecclesiastes from the Holy Bible; in particular, I was struck by the part about how the life of a man is a vanity. In my music, I have used a drone-like ostinato that permeates throughout the entire work. Using this as the long, seamless foundation of my piece, while delicate gestures are introduced up above, is something that would have been impossible if only acoustic instruments are used. / A Symphonic Poem / What is most unusual in this work is probably my choice to feature a duet for harp and marimba within a wind band. This piece begins with a few short, contrasting sections that are later combined with one another, and eventually grow to become one long stretch. Much of my attention in working through this piece has been focused on creating beautiful melodic lines that have irregular phrasings, yet will not interfere with the continuous musical flow. / Detailed summary in vernacular field only. / Detailed summary in vernacular field only. / Detailed summary in vernacular field only. / Detailed summary in vernacular field only. / Detailed summary in vernacular field only. / Detailed summary in vernacular field only. / Detailed summary in vernacular field only. / Detailed summary in vernacular field only. / Cheng, Ming Hin Henry. / "December 2012." / Thesis (M.Mus.)--Chinese University of Hong Kong, 2013. / Electronic reproduction.

Digital technology provides a very powerful medium for musical creativity, and the way in which we interface and interact with computers has a huge bearing on our ability to realise our artistic aims. The standard input devices available for the control of digital music tools tend to afford a low quality of embodied control; they fail to realise our innate expressiveness and dexterity of motion. This thesis looks at ways of capturing more detailed and subtle motion for the control of computer music tools; it examines how this motion can be used to control music software, and evaluates musicians' experience of using these systems. Two new musical controllers were created, based on a multiparametric paradigm where multiple, continuous, concurrent motion data streams are mapped to the control of musical parameters. The first controller, Phalanger, is a markerless video tracking system that enables the use of hand and finger motion for musical control. EchoFoam, the second system, is a malleable controller, operated through the manipulation of conductive foam. Both systems use machine learning techniques at the core of their functionality. These controllers are front ends to RECZ, a high-level mapping tool for multiparametric data streams. The development of these systems and the evaluation of musicians' experience of their use constructs a detailed picture of multiparametric musical control. This work contributes to the developing intersection between the fields of computer music and human-computer interaction. The principal contributions are the two new musical controllers, and a set of guidelines for the design and use of multiparametric interfaces for the control of digital music. This work also acts as a case study of the application of HCI user experience evaluation methodology to musical interfaces. The results highlight important themes concerning multiparametric musical control. These include the use of metaphor and imagery, choreography and language creation, individual differences and uncontrol. They highlight how this style of interface can fit into the creative process, and advocate a pluralistic approach to the control of digital music tools where different input devices fit different creative scenarios.

The aim of this thesis is to investigate techniques for, and applications of automatic sound synthesizer programming. An automatic sound synthesizer programmer is a system which removes the requirement to explicitly specify parameter settings for a sound synthesis algorithm from the user. Two forms of these systems are discussed in this thesis: tone matching programmers and synthesis space explorers. A tone matching programmer takes at its input a sound synthesis algorithm and a desired target sound. At its output it produces a configuration for the sound synthesis algorithm which causes it to emit a similar sound to the target. The techniques for achieving this that are investigated are genetic algorithms, neural networks, hill climbers and data driven approaches. A synthesis space explorer provides a user with a representation of the space of possible sounds that a synthesizer can produce and allows them to interactively explore this space. The applications of automatic sound synthesizer programming that are investigated include studio tools, an autonomous musical agent and a self-reprogramming drum machine. The research employs several methodologies: the development of novel software frameworks and tools, the examination of existing software at the source code and performance levels and user trials of the tools and software. The main contributions made are: a method for visualisation of sound synthesis space and low dimensional control of sound synthesizers; a general purpose framework for the deployment and testing of sound synthesis and optimisation algorithms in the SuperCollider language sclang; a comparison of a variety of optimisation techniques for sound synthesizer programming; an analysis of sound synthesizer error surfaces; a general purpose sound synthesizer programmer compatible with industry standard tools; an automatic improviser which passes a loose equivalent of the Turing test for Jazz musicians, i.e. being half of a man-machine duet which was rated as one of the best sessions of 2009 on the BBC's 'Jazz on 3' programme.

The PhD consists of a portfolio of electric-acoustic compositions and is accompanied by a scholarly dissertation. The portfolio of works explores the development of real time electro-acoustic composition techniques using microphone-captured audio. The portfolio focuses particularly on the voice as a sound source and aims to bring together the author’s background as a popular vocalist with her ‘music-concrete’ influenced electro-acoustic compositional work. The portfolio culminates in the development of a HCI (Human Computer Interface) called the eMic (eMic extended Mic-stand interface controller) which allows the performer to control sound parameters in real-time via common music performance gestures. / Doctor of Philosophy (PhD)
