This article outlines the development of an appropriate research approach, including methods from diverse disciplines, for researching the Colombian state-funded social music programme Music for Reconciliation ("Música para la Reconciliación"). After outlining the Colombian context and the literature, a pilot with ten participants is discussed. Findings show the contributions of sound postcards as part of life histories for capturing the experiences of displaced people in a country recovering from war. Their evocative capacity enriched the interviewees' narrative, illustrating diverse sonorous landscapes throughout their lives that evidenced the changes generated by both the violence and programme participation. The conclusions offer suggestions for readers based in the arts, health, social sciences and beyond, interested in the uses of music and music education for other-than-musical purposes.
