An analysis of the role which music played in shaping communities which remained peaceful and intact during the siege of Sarajevo, Bosnia-Herzegovina, during the war of the 1990s. Based on field research, this thesis concludes that music greatly strengthened communities through the building of musical capital, a synthesis of the many positive effects of music further analyzed in the work. Implications of the research suggest that music should be used in post-conflict community building, civic society development, and peace-building efforts.
