Music is an alternative for peacebuilding. This art is a tool to break the silence and narrate through melodies, lyrics and rhythms, not only the memories of death, forced displacement, impunity and disregard, but also of resistance, future dreams and hope. Despite the recent popularity and visibility of these initiatives, there is a conceptual gap that limits the capacity for analysis, feedback, innovation and expansion of this musical phenomenon that seems to have high potential in the field of peace research. This qualitative study invites the readers to go on a journey where sound will guide their transit through the pages of a text that seeks to articulate the peacebuilding theory of John Paul Lederach with Steven Feld s idea of acoustemology. According to Lederech, moral imagination and creativity play a key role in the consolidation of sustainable peace initiatives, and Feld proposes to embrace the sonorous as a source of knowledge about social life. Together, these theories form a bridge to answer the question: How do sonic practices currently contribute to peacebuilding in the urban area of San Andres de Tumaco?.
