This article presents an analysis of students' narratives regarding actions developed in public schools in northeastern Brazil. It is an extension project of doctoral research. These are actions involving music education, eco-political professionalism, and public pedagogy that seek to analyze the applicability of music in basic education with a bias towards acoustic ecology and the use of music as an art that fosters emotional engagement among those involved in environmental issues. This project is based on sustainable development and seeks to reflect on global policies such as the UNESCO 2030 Agenda. Qualitative, phenomenological research that used (auto)biographical narrative methodology to guide practical actions. For data collection, we conducted a focus group with second-year high school students, applied a questionnaire, conducted an eco-pedagogical walk, and hosted a musical event at the school. The authors participated in all stages of the project, which included the ecological musical, called ‘Grito Sonoro’ (Sound Protest), and the recording of a short eco-political, educational, and musical documentary film. The general objective was to investigate the contribution that music can make to students in relation to environmental issues. The specific objective was to foster the students' emotional engagement with sustainability issues and promote reflection on anthropic actions, supported by songs with lyrics that address environmental issues. As a result, the research highlighted environmental issues that directly affect the school and the community, such as the filling in of the lagoon, which is an environmental preservation area near the school. We seek actions that produce significant changes in the profession of music educators and their students. Musicality is inherent to human nature. The relationship that music establishes with the individual in relation to others is a cooperative practice. The value of music lies not only in its performance but also in its role as an educational tool, as it is understood as an important language in education. Through this research, we hope that music education practices—understood as part of a broader process—can serve as a tool for social development and transformation. The goal is to reach the core of the individual, fostering a more compassionate, environmentally conscious person with a broad and sensitive perspective.
