The region of Alcântara, Maranhão, Brazil, is a complex synthesis of a worldculture. Synthesis because it takes place in a microcosm, and complex because of the derivations and ramifications the clash of civilizations has generated as a culture. Reaching/touching a sound is an artistic, scientific and political effort by understanding sound as a world-system that connects everything, places sonic-visual thinking as a means of recognizing popular knowledge and a (trans)historical social critique of the (de)territorialization of Maranhão’s black and indigenous peoples. What results from our phenomenological observation, are photographic and cinematographic records, texts and sound recordings. What results from our methodological construction and interpretation is a film-essay conceived as a score to a live sound performance. On a theoretical level, we have used concepts and observations from sonic and musical studies (Johnson, 2023; Nancy, 2011; Chion, 2010; Jenny, 2001), as well as from visual studies and technical images (Flusser, 2014; Català, 2005; Arnheim, 1998). We started from audiovisual anthropology, bringing it into tension with a vivid dimension of practice as research (Henriques & D´Aquino, 2023), based on the experience of the researchers with sound and visual arts. The results give rise not only to a reflection on the path taken so far, as well as the future challenges in further research, to reverberate the struggle of quilombola people of Alcântara and sense how climate, territory and nature forge sonic culture, translating into language, politics and representation.
