Music therapists have traditionally worked with survivors of different types of trauma. But they are increasingly involved in providing services to war trauma survivors. In the post 9/11 world, many have been, and continue to be traumatized by war, acts of terrorism, and violence worldwide. Some music therapists have sought to respond actively to these events and the resulting trauma, by reaching out to trauma survivors. In addition, some are also involved in peace advocacy. From information obtained from interviews conducted with eight music therapists regarding the nature and outcomes of these therapeutic practices and their involvement in peace advocacy (as applicable), the relevance of this realm of work within the Singaporean context is explored.
