A cautionary note is that music can occasionally trigger PTSD. A number of veterans report that when they hear music they were listening to in combat prior to a traumatic event, it brings up the mood they were in during the trauma. This trigger can put them into a hypersensitive and hypervigilant state. It doesn’t just happen to people who were in combat. There are pieces of music that remind us of relationships gone bad, and the mere hearing of them can send us into a tailspin.
