<dcterms:abstract xml:lang="fr">Cette thèse de recherche-création explore les potentialités de l'univers percussif afro-brésilien pour la composition contemporaine à travers le concept de cavacar comme méthode d'investigation et de création. À partir d'une analyse critique du modernisme brésilien, je démontre comment l'opération de transsubstantiation, théorisée par Mário de Andrade, a fantomisé les matrices africaines et amérindiennes, les vidant de leur puissance épistémologique. En dialogue avec la théorie postcoloniale d'Achille Mbembe et l'hantologie de Derrida, je propose le concept d'assombralidade comme modalité spécifique de présence-absence qui, au lieu d'exorciser ces fantômes, permet de les habiter consciemment. M'inspirant de la tradition cosmogrammatique d'Afrique centrale et du concept de Ntunda (indissociabilité espace-temps), je développe une approche compositionnelle articulée en cinq dimensions du cavacar : creuser, fouiller, faire émerger, contourner le vide et collaborer. Le concept de HaKuMu(s) comme configuration sonore dotée d'une pulsation intrinsèque permet de traiter le rythme non comme structuration temporelle, mais comme champ complexe de médiations où la matière sonore est fondamentalement animée. Cette reconceptualisation transforme la relation entre compositeur, interprète et matériau sonore, proposant une éthique compositionnelle basée sur la collaboration et la reconnaissance mutuelle.</dcterms:abstract>
<dcterms:abstract xml:lang="en">This research-creation thesis explores the potential of the Afro-Brazilian percussive universe for contemporary composition through the concept of cavacar as a method of investigation and creation. Through critical analysis of Brazilian modernism, I demonstrate how the operation of transsubstantiation, theorized by Mário de Andrade, ghosted African and Amerindian matrices, emptying them of their epistemological power. In dialogue with Achille Mbembe's postcolonial theory and Derrida's hauntology, I propose the concept of assombralidade as a specific modality of presence-absence that, rather than exorcising these ghosts, enables their conscious inhabitation. Drawing on the cosmogrammatic tradition of Central Africa and the concept of Ntunda (space-time indissociability), I develop a compositional approach articulated through five dimensions of cavacar: excavating, mining, bringing forth, circumventing the void, and collaborating. The concept of HaKuMu(s) as a sonic configuration endowed with intrinsic pulsation allows rhythm to be treated not as temporal structuration, but as a complex field of mediations where sonic matter is fundamentally animated. This reconceptualization transforms the relationship between composer, performer, and sonic material, proposing a compositional ethics based on collaboration and mutual recognition.</dcterms:abstract>
