Sonidos e imágenes en la construcción de la persona mbyà-guaraní en el sur de Brasil

The mbya-Guarani sound world is an important dimension of theirexistence as well as their children are, through their presence and their songs, which occupy a central place in the oguata pora (Guarani sacred walk towards perfection). In this paper, I present ethnographic data on body processes and treatments as well as theories of visual and sound-performative practices that are part of the mbya way of being / living. the paper is, based on an ethnomusicological research among mbya groups in southern Brazil. From ethnographic descriptions an interpretation is built: a «cosmo-sonic» domain of ontology and epistemology of this Amerindian people, that is to say, that the construction of the mbya person— and the construction of knowledge are closely linked with sound processes, as well as to imagery, kinetic and material performances, that strengthen the listening and the resonance of the being.
