This portfolio of compositions investigates the adaptation of state-space models, frequently used in engineering control theory, to the electroacoustic composition context. These models are mathematical descriptions of physical systems that provide several variables representing the system’s behaviours. The composer adapts a set of state-space models of either abstract, mechanical or electrical systems to a music creation environment. She uses them in eight compositions: five mixed media multi-channel pieces and three mixed media pieces. In the portfolio, the composer investigates multiple ways of meaningfully mapping these system’s behaviours into music parameters. This is done either by exploring and creating timbre in synthetic sound, or by transforming existing sounds. The research also involves the process of incorporating state-space models as a real-time software tool using Max and SuperCollider. As real-time models offer several variables of continuous evolutions, the composer mapped them to different dimensions of sound simultaneously. The composer represented the model’s evolutions with either short/interrupted, long or indefinitely evolving sounds. The evolution implies changes in timbre, length and dynamic range. The composer creates gestures, textures and spaces based on the model’s behaviours. The composer explores how the model’s nature influences the musical language and the integration of these with other music sources such as recordings or musical instruments. As the models represent physical processes, the composer observes that the resulting sounds evolve in organic ways. Moreover, the composer not only sonifies the real-time models, but actually excites them to cause changes. The composer develops a compositional methodology which involves interacting with the models while observing/designing changes in sound. In that sense, the composer regards real-time state-space models as her own instruments to create music. The models are regarded as additional forces and as sound transforming agents in mixed media pieces. In fixed media pieces, the composer additionally exploits their linearity to create space through sound de-correlation.

Electroacoustic music and computer music come along with a vast variety of sources ranging from traditional score to complex digital performance set-ups. Approaches of documentation and archiving yet have not only to deal with the challenge of the rapid technological developments that cause the urge of updates in order to provide access to the content, the constant need of transfer also raises basic historical questions such as e.g. what to consider and thus save as historical testimonies of a musical works and its performances and how to include this instability of the sources within the embedded information. In my contribution, I will reflect on the mutual influence of technological challenges, the state of source material, approaches to documenting and archiving, and what this can mean for establishing new performances of these musical works. Hereby, I am especially interested in a structural reflection on the relationships between these processes and the resulting sources, as well as the question what this can mean for the (future and past) appearance of a musical work.

Theory as an approach to generative composition and interactive computer music. Inspired by the notion of Performance Indeterminacy, software has been developed that attempts to simulate the interactions of improvising performers using a multi-agent system based on the ‘Iterated Prisoner’s Dilemma’. Composition activities and programming activities have formed a symbiotic relationship throughout the creation of the portfolio as each has constantly informed the other. Stylistically, the works presented fall into the experimental genre, although individually they address a wide range of aesthetic goals. The main contribution of this portfolio is a new approach to generative composition based on behavioural models, creating a sense of form bottom-up through modelling the social dynamics of music performance. Through this approach, the direct modelling of musical structures is avoided; instead larger scale forms emerge through the interactions of an ensemble of ‘improvising’ agents. This method offers a departure from previous complex systems work in the area of music, creating computer models of specific musical situations. Links between the Iterated Prisoner’s Dilemma and music are also established and combined with current music technologies. / Thesis(Ph.D.)- University of Adelaide, Elder Conservatorium of Music, 2008

A. Mendes, sob a orientação da Profa. Dra. Aci Taveira Meyer. Teve por finalidade investigar a efetividade de módulos de educação musical, desenvolvidos dentro do Projeto Conexão do Saber da Unicamp, para o ensino musical em escolas brasileiras. Através da confecção de um módulo teste, centrado no parâmetro rítmico e métrico do som, e aplicação do mesmo em alunos de escolas da cidade de Pedreira no estado de São Paulo, foram feitas considerações sobre o impacto de utilização da ferramenta do Conexão do Saber. O teste foi aplicado em laboratórios de informática de escolas públicas. Para a obtenção desses dados, a abordagem metodológica utilizada foi a pesquisa experimental, por meio do delineamento quase-experimental com grupos experimentais e de controle e aplicação de um pré-teste e pós-teste. Investigou-se a eficácia de um módulo educacional mediante comparação de grupos que receberam o tratamento (aula virtual) ou não. Para a confecção do módulo e viabilização da coleta de dados, trabalhou-se com a situação de exploração auto-dirigida, não sendo levada em consideração a presença do professor ou monitor ao lado do aluno. O processo de organização, tratamento e interpretação das informações foi fundamentado em Campbell e Stanley (1979), além de Hosmer e Lemeshow (2000), de modo que foi feita uma análise heurística e um tratamento estatístico das respostas de 130 sujeitos. Neste estudo, percentuais e tabelas caminham lado a lado com reflexões sobre os resultados obtidos. Inicialmente, foi feita uma revisão bibliográfica sobre educação mediada por computador (EMC) na área de Educação Musical brasileira, identificando-se de que maneira o assunto está sendo abordado no país. Em seguida, apresenta-se o Projeto Conexão do Saber, seus módulos educacionais e especificamente as concepções de Educação Musical que permeiam a confecção desses módulos sob a ótica da pesquisadora. Depois, são apresentados os procedimentos metodológicos e a ferramenta do módulo teste. Há então um relato do processo de coleta de dados, expondo-se em seguida os resultados e a discussão das informações reunidas. Ao final, são feitas considerações sobre a eficácia da ferramenta do módulo teste e sobre o impacto pedagógico do Conexão do Saber para o desempenho dos alunos em relação à aprendizagem e, mais especificamente, em relação à aprendizagem musical. / Abstract: The following paper presents the doctoral research which was developed in the Art Institute of Unicamp by Adriana N. A. Mendes, under the guidance of Professor Dr. Aci Taveira Meyer. It aimed to investigate the effectiveness of music education modules, developed at the Conexão do Saber project of Unicamp, for the teaching of music at Brazilian schools. By setting up a test module, focused on the rhythmic and metric parameter of sound, and applying it to students of schools in the city of Pedreira in the state of São Paulo, considerations about the impact of using the Conexão do Saber tool are made. The test was conducted at IT labs of public schools. To obtain this data, the methodological approach used was experimental research, through quasi-experimental delineation with experimental and control groups, having pre-tests and post-tests. The paper investigates the efficiency of an educational module by means of comparisons of groups which received the treatment (virtual class) or not. To set up the module and gather the data, a self-induced exploration scenario was used, not taking into consideration the presence of the teacher beside the student. The process of organization, treatment and interpretation of data is grounded in Campbell and Stanley (1979), as well as Hosmer and Lemeshow (2000), such that a heuristic evaluation and a statistical treatment of the answers of 130 subjects are done. In this study, percentages and tables go hand in hand with reflections on the results obtained. Initially, a bibliographical review on education mediated by computers (EMC) in Brazilian music education was done, identifying the way in which the subject is being approached in the country. Then, the Conexão do Saber project is presented, its educational modules and specifically music education conception which permeate the making of these modules under the researchers view. Later, the methodological procedures and the module test tool are presented. The data collecting process is reported, followed by the exposure of results and discussion of the information gathered. The results are exposed and the data collected is discussed. Finally, considerations about the efficiency of the module test tool and about the pedagogical impact of Conexão do Saber for the students' performance in relation to learning and, more specifically, in relation to music learning are made. / Doutorado / Fundamentos Teoricos / Doutor em Música

Computer-generated music composition programs have yet to produce creative, natural sounding music. To date, most approaches constrain the search space heuristically while ignoring the inherent structure of music over time. To address this problem, this thesis introduces NEAT Drummer, which evolves a special kind of artificial neural network (ANN) called compositional pattern producing networks (CPPNs) with the NeuroEvolution of Augmenting Topologies (NEAT) method for evolving increasingly complex structures. CPPNs in NEAT Drummer input existing human compositions and output an accompanying drum track. The existing musical parts form a scaffold i.e. support structure, for the drum pattern outputs, thereby exploiting the functional relationship of drums to musical parts (e.g. to lead guitar, bru:is, etc.) The results are convincing drum patterns that follow the contours of the original song, validating a new approach to computergenerated music composition.
