A presente pesquisa teórico-prática apresenta uma análise interdisciplinar da poética de obras de performance audiovisual, multimídia e intermídia, com ênfase em como a performatividade e a presença do artista na execução de sua obra estão imbricados na forma do trabalho, cuja composição é permeada por questões relacionadas ao seu dispositivo técnico. Ao abordar situações específicas de obras que imprimem movimento à forma final, a partir das quais consideramos evidenciarse a manifestação da \"mente corporificada\" do criador e inventor como ponto de conexão entre poética e meios empregados para sua execução, chegamos ao princípio das modalidades de presença poética, a partir do qual discutimos as relações entre corporalidade, performatividade e dispositivo técnico. Através de processo laboratorial de instauração de poética de trilogia de performances multimídia intitulado #LiveLivingPerformanceProject chegamos aos pontos teóricos relevantes do trabalho, entre eles os conceitos de mente corporificada (embodied mind), duplo digital (digital double), digital self e audiovisualidade sincrética digital. O projeto artístico multimídia resultante da pesquisa erige-se em um simbolismo transcendental, de livre adaptação e interpretação de arquétipos de mitologias femininas afrobrasileiras e a partir de especificidades da sabedoria dos povos originários, todos relacionados com os elementos da natureza, que serão foco central de instauração de poética do projeto. Calcados nos elementos da natureza, como forças fundantes de personificações simbólicas e psíquicas, demonstraremos como chegamos ao cerne da poética instaurada em #LiveLivingPerformanceProject ao longo do processo de investigação. Ao experimentar variadas interfaces digitais e sistemas audiovisuais, cruzando nossa experiência prática com observação de processos de instauração de trabalhos de performance, formamos nossa análise através da coesão entre processos práticos e operacionalização de conceitos de diferentes campos da filosofia, das artes das imagens em movimento e das performance arts que discutem questões como visibilidade, multimidialidade, intermedialidade, dispositivo técnico, poética, presença e duplo digital. / This practice-based thesis introduces an interdisciplinary analysis of the poetics of audiovisual performance, multimedia and intermedia works. Emphasizing on how the performativity and the presence of the artist in the execution of his work are intertwined in the form of the work; whose composition is permeated by issues related to its technical device. When discussing specific work situations that attach movement to the final shape; from which we consider evidencing the manifestation of the creator / inventor\'s \"embodied mind\" as the connection point, between poetic and the means employed for its execution, we come to the principle of presence modalities, from which we discuss the relationship between corporeality, performativity and technical device. By means of a laboratorial process to establish the trilogy of multimedia performance poetics, entitled #LiveLivingPerformanceProject, we come to the theoretical points that are relevant to the work, as embodied mind, digital double, digital self and digital syncretic audiovisuality. The multimedia artwork that results from the research is built in a transcendental symbolism. Of free adaptation and interpretation of the mythology of female African- Brazilian archetypes, as well as influences of the knowledge of native American peoples; all related to the elements of nature, that will be the central focus of the introduction of the poetics of the project. Paved with the elements of nature as the psychic and symbolic personifications founding forces, we will demonstrate how we got to the heart of the poetics, which is established throughout the research process. When experimenting with various digital interfaces and audiovisual systems, crossing our practical experience by observing establishment processes of performance projects, we form our analysis through the cohesion between practical processes, and operational concepts from different fields of philosophy, arts of moving images and performance arts, which discuss issues such as visibility, multimediality, intermediality, technical device, poetics, presence and digital double.

This dissertation thesis describes the phenomenon of audiovisual performance in different connotations. A substantial part is devoted to psychological survey into my own subconscious and subsequently to metaphorical processing of this introspection. An important part of the work is a resume of the general knowledge of the physical properties and its metaphorical application on mental and creative processes. This analysis and explanation of internal cognitive models are implemented in terms of the study of relationships, interactions based on cooperation or confrontation, but also the inability to grasp the objective reality from the subjective position due to the merged distinctions of real and fictional. The importance of audiovisual performance is also studied in linear perspective of history, in order to point out the general principle of repetition patterns, which reveals that audiovisual performances is an activity which is a necessary expression of life itself and not just the concept in the field of arts.

The goal of this thesis is to describe the influence of technological development on the ways in which the moving image is created and to introduce forms that this medium attains in the area of live audio-visual performances. The theoretical study approaches this topic as a historical overview of technical image, focusing on its connections with music. It thus observes specific creative processes of the avant-garde film and music video and subsequently puts them into the context of current types of moving picture created as a result of software codes. Based on the definitions of digital media's key principles, a theoretical basis is set up and then applied to the description of contemporary forms of audio-visual performances. These principles are also used for the definition of the features of software tools, numeric representations of which make it possible to work with any type of an image as with a set of mathematical functions. The main result of this thesis is thus a presentation of creative possibilities of today's image, which has - thanks to digital devices - disengaged itself from its previous technical limitation and become a fully dynamic element that can be created and modified in real time.

Les moyens technologiques de la musique électronique reconfigurent les pratiques musicales. Du fait des procédures de computation et d’automation inhérentes aux machines qui médiatisent le phénomène sonore, ces moyens ont notamment la particularité d’introduire une rupture dans le rapport causal entre le geste instrumental et le son produit. Que signifie alors jouer de la musique électronique ? Comment comprendre ici les concepts de geste et d’instrument de musique qui sont traditionnellement mobilisés pour analyser les pratiques musicales ?Pour répondre à ces questions, nous avons mené entre 2010 et 2016 un travail de terrain auprès de musiciens professionnels dans des contextes musicaux variés : musique savante avec électronique en temps réel, performance audiovisuelle et musique électronique populaire. Cette approche, focalisée sur l’instrument, permet de questionner la matérialité des pratiques électroniques en la plaçant au premier plan, par-delà les esthétiques musicales. Ce travail consiste donc en une « enquête organologique » sur les pratiques des musiciens ou des groupes suivants : Robert Henke, Alex Augier, Brain Damage, High Tone, Pierre Jodlowski, Jesper Nordin, John MacCallum et Teoma Naccarato, Nicolas Mondon, Greg Beller et le collectif Unmapped. La méthode ethnographique permet de circonscrire l’usage particulier des technologies musicales à différents moments du processus de création : conceptualisation de l’œuvre, collaboration technique, réalisation artistique et performance scénique. À partir de l’analyse de l’activité musicale au prisme des configurations instrumentales, nous proposons une typologie des instruments électroniques dont le critère de classification est le geste, unique résidu du modèle acoustique de l’interaction instrumentale. L’activité corporelle permet donc d’ordonner la diversité matérielle des technologies musicales en même temps qu’elle constitue un vecteur stratégique d’expression de l’interaction instrumentale. / Technological means of electronic music reconfigure musical practices. Because of the machines’ computation and automation capacities that mediate the sonic phenomenon, the causal relationship between instrumental gesture and sound is altered. Therefore, what does it mean to play electronic music? The concepts of gesture and musical instrument are traditionally employed for the analysis of musical practices, but how should they be understood in this context? To address these issues, we conducted an extensive fieldwork between 2010 and 2016 with professional musicians in various contexts: art music with real-time electronics, audiovisual performance, and popular electronic music. Our instrument-focused approach allows us to consider the materiality of electronic music itself, beyond aesthetics. Thus, this work is an “organological inquiry” on the following musicians or bands: Robert Henke, Alex Augier, Brain Damage, High Tone, Pierre Jodlowski, Jesper Nordin, John MacCallum and Teoma Naccarato, Nicolas Mondon, Greg Beller, and the Unmapped collective. The ethnographic method sheds a light on the use of music technologies at different stages of the creative process: conceptualization of the work, technical collaboration, the making of the music and its performance. From this analysis of musical activity captured through instrumental configurations, we offer a typology of electronic music instruments, based on a gestural criterion, which is the only residual aspect of the acoustic instrumental interaction model. The corporeal activity leads to organise the material diversity of music technologies, as well as it constitutes a strategic way to express instrumental interaction.

The subject of the thesis Live images of VJing is an aesthetic activity, based on visual projections and on work with new media in real-time, known as VJing, or more generally "live audiovisual performance". As these performances usually complement auditory events or are supplemented by music. The first part follows the origins of VJing out of three angles: First the historical development of projected image, electronic music and the discourse of synaesthesia principle as an principle joining different sensory perceptions into one. Second part of this thesis is introducing an philosophical perspective and it's defining terms, through which can be glimpsed the tendencies in the development of contemporary art of new media, particularly following the example of the German new-media philosophy with terms like homöotechnik, performativity, mediality and gesture. The outcome of this thesis is the finding, that it's not the media-philosophy bringing the textures and shapes to VJing, but the opposite - VJing as an art form is a valuable contribution to defining of the media-philosophy, which seem to be forming along with the new media itself and with the experimental arts exploring it's radical possibilities.
