This portfolio comprises of a collection of acousmatic works which investigate the role of source bonding in music – the tendency of listeners to relate sounds to their real-world sources and the signifying implication of such a link – with a particular focus on how spatial design can contribute towards source-bonding in the music’s perception as a holistic spatio-sonic entity. A number of compositional strategies, multichannel formats and spatial audio technologies are investigated, with their merits assessed based on their suitability for shaping the qualities of musical space explored. The discussion in this commentary will show how these holistic spaces can have similar qualities of perceived ‘reality’ and ‘abstraction’ to the individual sounds, and how this is investigated in the musical works. I shall also show how the contrasting environmental qualities of these spaces became a source of of inspiration for structuring the development of my music, and how they might evoke subsequent meaning in their experience based on the listener’s understanding of the spatial source bonds.

The five-course guitar was used as an instrument of accompaniment from the mid-sixteenth to the late-eighteenth century, yet its importance in this role has largely been overlooked in scholarship to date. While there are some isolated studies of individual sources, this is the first comprehensive study of the substantial body of extant guidelines with a view to understanding the styles of accompaniment on the instrument and how their practices developed during this period. This thesis documents the chronological development of the performance practices in such a way that parallels may be drawn between these sources and treatises for other instruments of accompaniment. Guitar accompaniments were, however, also strongly influenced by the performance practices associated with alfabeto chord symbols. Thus, to enable an understanding of the more idiomatic characteristics of guitar accompaniment stemming from alfabeto practices, a detailed evaluation of the true sophistication of the language of alfabeto is provided for the first time. This study provides a complete re-evaluation of the five-course guitar as an instrument of accompaniment; it challenges the past relegation of the instrument to ‘light’ or ‘frivolous’ musical repertoires; and it highlights the various approaches that were adopted in diverse performance contexts.

This research forms part of a performance practice degree and focuses on the performance of British organ music written in the period 1945 to 1970. This period was a turbulent time for all those with an interest in the pipe organ, whether they were performers, consultants, organ builders or listeners. The considerable change in the approach to the design, construction and voicing of pipe organs, influenced by the Organ Reform Movement (Orgelbewegung), resulted in strong feelings both for and against the neo-classic organ, and the consequent tensions tested the typical British reserve of many of those directly involved. The challenge for the performer of today is to understand the strengths and weaknesses of British organs in the period and to connect these instruments with the music written for them. The original contribution this research provides is to focus firstly on the organ's mechanisms, including key actions, registration aids and console design and, secondly, on the tonal designs of the organs of the period. Case studies of music are presented, featuring three composers for the organ in this period, Howells, Leighton and Whitlock, the findings of which inform the associated recital which features contrasting pieces from the period 1945 to 1970.

The current thesis is a portfolio of ten musical works composed during the period of 2011 and 2015, including instrumental, mixed media and acousmatic (stereo and multichannel) compositions. These works were developed and composed at my home studio in Oporto (from 2011) and at the Electroacoustic Music Studios at the University of Birmingham (2014 – 2015). This thesis also features observations and commentaries about technical and aesthetical issues that were objects of study during my creative process, which uses musical elements from my culture as inspiration for new musical works. Hence, it presents a reflection on and the validation of results that came from the exploration of several procedures during my development at the University of Birmingham Electroacoustic Music Studios and a chapter dedicated to the traditional instrument from the Azores – the viola da terra – and the two compositions that focus on this instrument. A USB stick is attached to this thesis, containing the audio performances of all musical works, scores and electronic version of this document.

This thesis presents the librettos, scores and CD recordings of two contemporary operas – The Wings of Daedalus and Alexandros – conceived, composed and, in the case of The Wings of Daedalus staged, by myself, along with detailed analysis of the development phases of various different aspects (such as dramaturgy, libretto, staging and characterisation, and particularly the composition of the vocal line and electronic accompaniment of each opera), following them from the initial idea to the final result. All this is paralleled with the period in the development of Western music four hundred years ago that led to the birth of opera. That transitional phase is correlated with my work and its contemporary context, as seen from various viewpoints. I have chosen The Theory of the Affections as an exemplary connecting point between these chronologically distant eras in music, and used it to identify important links between compositional intention and vocal practice in the years leading up to 1600 and those leading up to 2000. This in turn leads me to explain specifically my own compositional techniques - many of which are radically unusual and correlate them with The Theory of the Affections as approaches to creating opera.

Estudos petrográficos, mineralógicos e isotópicos (radiogênicos (Sm/Nd) realizados em xenólitos mantélicos registrados em kimberlitos de Juína sugerem que o manto superior abaixo dessa região é composicionalmente estratificado e composto principalmente de peridotitos e eclogitos. Entre os xenólitos encontrados, peridotitos são os mais abundantes e representados por granada peridotitos e granada \'+OU-\'espinélio peridotitos. Granada \'+OU-\' espinélio peridotitos exibem texturas equigranulares e intensa silicificação substituindo olivina e ortopiroxênio por quartzo criptocristalino, assim podendo ser subdivididos em granada \'+OU-\' espinélio peridotitos com assinatura de eclogitos (GEPE) e granada \'+OU-\' espinélio peridotitos silicificado (GEPS). GEPE exibem abundantes agulhas de rutilos incluídas em clinopiroxênios(CPX) e granadas(GRT). Nestes xenólitos ocorrem os CPX com os maiores conteúdos de \'AL IND.2\'\'O IND.3\' e as GRT com os menores teores de CaO de todos os peridotitos. GEPE apresentam elevado conteúdo de elementos incompatíveis, e (até 2.313 vezes ao do manto primitivo) e enriquecimento em ETRs leves nos CPX, com [\'La/Yb] IND.N\'\'>OU=\'1. São caracterizados por equilíbrio em temperaturas (881 a 907°C) e pressões (26 a 33 kbar) relativamente baixas. Mostram valores negativos de \'\'épsilon\'IND. Nd\'(-11,06) e idade modelo (\'T IND.DM\') de 1.884 Ma. GEPS representam os xenólitos mais abundantes dos peridotitos. Contêm menores inclusões de rutilo e forte modificação por processo de silicificação. Apresenta CPX com maior conteúdo de MgO e enriquecimento nos incompatíveis e ETRs [\'La/Yb] IND.N\'\'>OU=\'1, e GRT com conteúdo intermediário de \'Cr IND.2\'\'O IND.3\' e empobrecimento em ETRs pesados [\'Dy/Yb] IND.N\' < 1, se comprado aos demais. Foram equilibrados em temperaturas e pressões respectivamente entre 1077 a 1353°C e 50 a 63 kbares. Mostram valores negativos \'épsilon\'Nd (-8,35 a -11,31) e idade modelo (\'T IND.DM\') de 1.842 a 1114 Ma. Granada peridotitos com texturas 1 e 2 (GPT1 e GPT2) exibem severas texturas de deformação, com formação de neoblastos de olivina principalmente. GPT1 mostra-se mais enriquecida em porfiroclasto de olivina e menor conteúdo de granada, com CPX tendo maior conteúdo de CaO; já no GPT2 a GRT é mais enriquecida em \'TiO IND.2\'. GT1 e GT2 apresentam os menores conteúdos de elementos incompatíveis (ETRL~10 vezes o do condrito) dos peridotitos. Foram equilibrados em temperaturas e pressões entre 1084 a 1473°C e 37 a 58 kbares no GPT1 e 1263 a 1408°C e 40 a 60 kbares no GPT2. Mostram valores negativos de \'épsilon\' Nd(-3,24) e idade modelo (\'T IND.DM\') de 1.242 Ma. O conteúdo elevado de elementos incompatíveis, com enriquecimento de ETRs leves no CPx e empobrecimento na GRT, sugere que os xenólitos peridotíticos representam uma fonte de manto enriquecida do tipo EM, com \'\'épsilon\' IND.Nd\' negativos e razão Sm/Nd <1. Assim pode-se inferir que esses peridotitos foram formados por fracionamento ígneo no manto superior, litosfera para GEPE e GEPS e astenosfera para GPT1 e GPT2, sendo assim resíduo de extração de líquido basáltico (Ex.: vulcânicas do Grupo Roosevelt). Peridotitos messomatizados (MARID) representam a cristalização de minerais metassomáticos (Modal) e enriquecimento anômalos de elementos traços e ETRs, e poderiam estar associados a uma origem concomitante com o evento carbonatitíco - kimberlítico. Os xenólitos de eclogitos são mais raros e podem ser divididos em três grupos: i) Eclogitos bi-minerálicos (EB), ii) Ortopiroxênio - rutilo eclogitos (ORE); e iii) Sanidina - quartzo - coesita eclogitos (SQC). O conteúdo modal de granada aumenta do ORE para EB até SQC. Neste mesmo sentido ocorre um aumento da molécula de grossularita na granada e do teor de \'AL IND.2\'\'O IND.3\' em clinopiroxênio. EB e ORE apresentam composição química de eclogitos do Grupo A ou I. SQC têm composição similar aos do Grupo B ou II. Apresentam razões isotópicas variáveis desde positiva \'\'épsilon\'IND.Nd\' + 0,16 (ORE) até valores negativos elevados \'\'épsilon\'IND.Nd\' - 13,03 (EB), e idade modelo (\'T IND.DM\') entre 1166 a 1648 Ma. A isócrona interna entre CPX, GRT e rocha total de dois eclogitos (EB e ORE) apresentou uma idade de cristalização e/ou recristalização de 200 Ma, corroborando assim a hipótese de que os eclogitos foram formados por subducção de crosta oceânica (Pro-Pacífico) em baixo do Supercontinente Gondwana durante o Mesozóico. Porém, não se descarta a hipótese de que os eclogitos (EB e ORE) poderiam ser considerados cumulados ígneos de alta pressão e/ou resíduo de fusão de líquidos basálticos durante eventos Mesoproterozóicos. A suíte de megacristais (LICPX) apresenta conteúdo de baixo cromio e portanto com afinidade aos eclogitos. Pode ser interpretada como formada durante co-precipitação de clinopiroxênio pobre em cromo e picroilmenita a temperatura entre 1264°C e 1308°C, em um líquido proto-kimberlítico. / Mineralogical, petrographic and isotopic studies (radiogênicos (Sm/Nd) mantélicos xenoliths in kimberlites of Juína suggest that the upper mantle below this area is compositionally stratified and composed mostly of peridotite and eclogite. Between xenoliths found, peridotite are the most abundant and represented by granada and granada \'+OR-\' spinel peridotite. Granada \'+OR-\' spinel peridotite exhibit intense silicification and equigranulares textures by replacing olivine and orthopyroxene by criptocristalino quartz, so can be subdivided into granada \'+OU-\' spinel peridotite with signature of eclogite (GEPE) and granada \'+OR-\' spinel peridotite silicificado (GEPS). GEPE display abundant rutilos needles included in clinopiroxênios (CPX) and grenades (GRT). In these xenoliths CPX occur with the highest content of Al2O3 and the GRT with the lowest levels of all of peridotite. GEPE have high contents of incompatible elements, and (until 2,313 times primitive mantle) and enrichment in light in CPX, ETRs with [\'La/Yb] IND.N\'\'>OU=\'1. Are characterized by balance in temperature (881 to 907°C) and pressures (26 to 33 kbar) relatively low. Show negative values of \'\'épsilon\'IND. Nd\' ( -11.06) and age model (TDM) of 1,884 Ma. GEPS represent the most abundant xenoliths of peridotite. Contain rutile inclusions and strong minor modification by silicification process. Presents more MgO content CPX and enrichment in incompatible and ETRs [\'La/Yb] IND.N\'\'>OR=\'1, and GRT intermediate content of Cr2O3 and impoverishment in heavy ETRs [\'Dy/Yb] IND.N\' < 1, compared to others. Were equilibradoss in temperatures and pressures respectively between 1077 the 1353° C 50 to 63 and kbares. Show negative values of \'épsilon\'Nd (-8.35 to -11.31) and age model (TDM) of 1,842 the 1114 Ma. Garnet peridotite with textures 1 and 2 (GPT1 and GPT2) exhibit severe deformation textures, with formation of neoblastos of olivine. GPT1 shows more enriched in olivine porfiroclasto and lower contents of garnet, with higher CaO content in the CPX, while the GRT GPT2 is more enriched in TiO2. GT1 and GT2 have the smallest contents of incompatible elements (ETRL ~ 10 times the chondrite) of peridotite. The equilibrium temperatures and pressures were between 1084 and 1473 ºC, and 37 to 58 kbars for GPT1, respectively, and 1263 to 1408°C and 40 to 60 Kbars for GPT2. Show negative values of \'épsilon\'Nd (-3.24) and age model (TDM) of 1,242 Ma.The high content of incompatible elements, with enrichment of light in CPX and ETRs impoverishment in GRT, suggests that the xenoliths represent a enriched mantle source type, with negative \'épsilon\'Nd and Sm/Nd < 1. It could be inferred that these were formed by igneous fractionation peridotite in the upper mantle, then lithosphere for GEPS and GEPE and asthenosphere for GPT1 and GPT2, being basaltic liquid extraction residue (e.g. Group volcanic Roosevelt). Metasomatized peridotite (MARID) represent the crystallization of metasomatic minerals (Modal) and anomalous enrichment of trace elements and ETRs, and it could be associated with a concomitant with the event source carbonatitic-kimberlitic. Xenoliths of eclogite are rare and they can be divided into three groups: i)bi-minerálicos Eclogite (EB), ii) Orthopyroxene-rutile eclogite (ORE); and iii) Sanidinequartz-coesite eclogite (SQC). The modal content of garnet increases of the ORE for EB to SQC. In this same sense is an increase of grossularite molecule in garnet and Al2O3 in clinopyroxene. EB and ORE present chemical composition of group. A or Group I eclogite. SQC have composition similar to group B or II. Exhibit isotopic variables from positive reasons \'épsilon\'Nd + 0.16 (ORE) until negative values high \'épsilon\'Nd -13.03 (EB), and age model (TDM) between 1166 to 1648 Ma.The internal isochrone CPX and GRT, and two whole rock eclogites (EB and ORE) presented a crystallization age and/or recrystallization of 200 Ma, corroborating the hypothesis that the eclogite were formed by the subduction of oceanic crust (Proto) at the bottom of the supercontinent of Gondwana during the Mesozoic.However, do not rule out the hypothesis that the eclogite (EB and ORE) could be considered cumulus of high-pressure igneous and/or melting basaltic liquid residue during mesoproterozoics events.The megacristais suite (LICPX) features low Cr content, with affinity to eclogite. Can be interpreted as formed during the co-precipitation of low chromium clinopyroxene and picroilmenite, below temperatures between1264° C and 1308° C in a liquid proto-kimberlitic.

The current submitted work consists of a portfolio of musical works, visual pieces and thoughts that preoccupied me over a period of research and creation from late 2014 to 2017. Pieces described in this thesis developed into an overall artistic research and craft which led to a specific workflow serving a new personal aesthetic. Two parts describe two seemingly antonymous automatic creation processes: automatic versus automatic. The first part describes my inspirations together with a consequent formal-ization of my composition techniques. I render generative automatic music both emerging from finite state computation and infinitesimal interference. The second part shows that I often perform my music in specific sites with challenging conditions. I consider them as constraints that eventually also be-come part of the composition system. The materialization of a piece involves aback-and-forth process, between concepts and realities, that I finally transcend in the sense of surrealist automatism. This mechanical and human process is a necessity for the authenticity to my pieces.

This text is a commentary on my preoccupations over the course of my doctoral research from 2013 to 2017. It accompanies a portfolio of works realized and submitted as part of this doctoral thesis, which looks more specifically at feedback as an iterative process between myself as instrument-builder, composer and performer. This approach, which puts sound center stage as the primary material, emphasizes the organic and bidirectional internal influences among these three creative poles. This thesis is devoted to the main subject of my doctoral research: the notion of creative feedback among instrument-builder, composer and performer. It is in five parts: 1. A definition of my principal influences and aesthetic biases; 2. A portrait outlining the connections of influence among the instrument-builder, composer and performer; 3. A discussion of relationships outside the creative process itself, that is to say the influence of other artists (composers, musicians, other instruments) in my approach to research creation; 4. A demonstration of how I use the influences of other composers, other musicians and even other artists whose works speak to and inspire me; and 5. A presentation of three concrete examples from the portfolio realized during my doctoral research The body of work submitted includes: three new instruments, two sound installations,four compositions and three comprovisations.

O mapeamento geológico (esc.1:100.000) realizado na região do Distrito de Cachoeirinha, sudoeste de Mato Grosso, revelou a existência de dois grandes conjuntos de rochas: o Grupo Alto Jauru, uma sequência vulcano-sedimentar do tipo greenstone belt, e as Unidades Intrusivas representadas por gnaisses granodioriticos (Gnaisses São Domingos) e monzograniticos (Gnaisses Aliança), tonalitos orientados (Tonalito Cabaçal), um batolito monzogranitico com sienogranitos e granodioritos minoritários (Suíte Intrusiva Santa Cruz) e, finalmente, monzogranitos maciços (Suíte Intrusiva Alvorada). O Grupo Alto Jauru exoõe-se como um cinturão estreito e alongado (Sinforme da Fazenda Sudam) com orientação em torno de N20°W ou como megaxenólitos distribuídos no interior das Unidades Intrusivas. Os fragmentos são essencialmente hor nblenda anfibolitos cinza escuro, orientados, de granulação fina a média. A parte exposta no cinturão foi dividida em duas unidades informais: a unidade dos biotita-muscovita-granada gnaisses e dos muscovita-sillimanita-biotita xistos. A primeira ocorre na região mais externa da sinforme, constitui-se essencialmente por biotita-muscovita-granada gnaisses com intercalações subordinadas de tremolita-clorita xistos, tremolita-actinolita anfibolitos muscovita-quartzo xistos; a outra unidade, constitui-se de granada-muscovita-sillimanita-biotita-xistos e se restrige ao núcleo da estrutura dobrada. As rochas gnáissicas são representadas pelos Gnaisses São Domingos e Aliança que, na ausência de dados conclusivos, foram posicionados como contemporâneos. O primeiro é composto por gnaisses cinza escuros e cinza escuro rosados, equigranulares, de granulação média a grossa, de composição modal equivalente a dos granodioritos. Os Gnaisses Aliança são cinza claros, de granulação média e raramente grossa e possui composição modal monzogranitica. Integram ainda as Unidades Intrusivas: o Tonalito Cabaçal, um corpo estreito e alongado, constituído por rochas cinza escuras, de granulação média a grossa, equigranulares, fortemente orientados e com milonitização nas bordas; a Suíte Intrusiva Santa Cruz, um batólito alongado, composto por duas facies distintas: uma, a base de rochas róseas, grossas, orientadas, de composição monzogranitica e raramente sienogranitica, e outra composta por granodioritos grossos, equigranulares e orientados: finaliza o magmatismo, um conjunto de stooks circulares a subcirculares constituídos por rochas cinza claras e rosa acinzentadas, equigranulares, granulação fina a média e composição mozogranitica (Suíte Intrusiva Alvorada). A análise estrutural revelou uma história deformacional com pelo menos três fases super impostas de dobramentos. A primeira (D1) caracteriza-se pelo desenvolvimento de uma foliação penetrativa S1 (bandamento ou xistosidade) com orientação em torno de N50°-60°W/60°-70°NE e raramente SW, observada no Grupo Alto Jauru, Gnaisses São Domingos e Aliança. A fase Dz é marcada pelo desenvolvimento de dobras apertadas a cerradas, assimétricas, isoclinais, desenhadas pelas superfícies S1. A foliação Sz é principalmente uma clivagem de crenulação ou uma xistosidade paralela a S1 e visível nos Gnaisses e supracrustais. No tonalito Cabaçal e Suíte Santa Cruz é definida por uma xistosidade com atitude em torno de N50°-60°W/60°-70°NE. A fase Da desenvolveu estruturas localizadas e é marcada por dobras abertas, simétricas a assimétricas, com eixo caindo para NE. A foliação plano axial é uma clivagem de crenulação ou de fratura com orientação de N30°-40°E/65°-75°SE, indicando vergência para SE. / The geologic mapping (scale 1:100.000) made in the region of Cachoeirinha District. Sothwet of the state of Mato Grosso. , has shown the existence of two large sets of rocks: the Alto Jauru Group, a volcano-sedimentary sequence of the greenstone belt lype, and the Intrusive Units represented by granodioritics gneisses (São Domingos Gneisses) and monzogranitics (Aliança Gneisses) oriented tonalities (Cabaçal Tonalite), a monzogranitics batolito with minority sienogranites and granodiorites (Santa Cruz Intrusive Suite) and, finally, massive monzogranites (Intrusive Suite Alvorada). The Alto Jauru Group outcrops as a narrow and alongated belt (sinforme of the Sudam Farm) with orientation of abount N20W or as megaxenolites distributed in the interior of the Intrusive Units. The fragments are mainly oriented light gray hornblende anfibolite, with a fine to medium granulation. The outcropped part of the belt was divided in two informal units: the biolite-muscovite-garnet gneisses and the muscovite-sillimanite-biolite schists. The former appears in the most external region of the sinform, and is mainly composed of biotite-muscovite-garnet gneisses with intercalations subordinated of tremolite-clorite schists, tremolite-acnolite anfibolites and muscovite-quartz schists; the latter is formed by garnet-muscovite-sillimanite-biolite schists and restricted to the folded structure core. The gneissic rocks are represented by the São Domingos and Aliança Gneisses which, in the absence of concluding data, were placed as contemporary. The former is composed by dark-gray and dark pinkish-gray gneisses which are equigranulates, of a medium to thick granulation, and a modal composition equivalent to the granodiorites. The Aliança Gneisses are light gray, of a medium rarely thick granulation and has a monzogranitic modal composition. The Intrusive Units are also composed of Cabaçal Tonalite, which is a narrow and alongated body, formed by dark-gray rocks, of medium to thick granulation, which is equigranulated, strongly oriented and with milonitization in its borders; the Santa Cruz Intrusive Suite, an alongated batolite, composed of distinct facies: one, made of oriented thick pink rocks, of monzogranitic and rarely sienogranitic composition and the other composed of thick, equigranulated, oriented granodiorites; the magmatism ends in a set of circular to subcircular stocks made of loght gray grayish pink rocks, which are equigranulated, of a fine to medium granulation and monzogranitic composition (Alvorada Intrusive Suite). The structural analysis has shown a deformational history with at least 3 superposed folde phases. The former (D1) is characterized by the development of a penetrative foliation S1 (banding or schistosity) with orientation of about N50-60W/60-70 NE and rarely SW, observed in the Jauru Group, São Domingos and Aliança Gneisses. The Dz phase is marked by the development of closed to thick folds, which are assimetric, isoclinal, designed by the S1 surfaces. The Sz foliation is mainly a crenulation cleavage or a schistosity that is parallel to S1 and visible in the Gneisses and supracrustals. A schistosity with attitude of about N50-60W/60-70 NE is defined in the Cabaçal Tonalite and Santa Cruz Suite. The Da phase has developed a localized structure and is marked by opened folds shich are assimetric, with its axis plunging to the NE. The axial plane foliation es either a crenulation or a fracture cleavage with orientation of about N30-40E/65-75 SE, indicating vergence to SE.
