Don Cambell writes in a personal, engaging style, making the readers enjoy pursuing the premises which he purports to explore. Ranging in style from personal anecdotes to hard scientific evindence from peer-reviewed journals, Campbell attempts to build a case for the ability of music to heal a wide range of mental and physical ills.
Unfortunately, the evidence simply is not there on a scientific level. Though there are an impressive number of success stories in the book, the actual, citable research is scarce, especially for effects of music on physical health. Most of the replicable research to date concerns itself with effects mediated though stress reduction pathways: heart rate, blood pressure, and the like. When one looks for evidence of music altering immune function and disease course, the evidence becomes almost nonexistent.
Campbell seems to treat almost all forms of evidence as equal; from anecdotes to articles in the popular press, to scientific ! ! studies. A more stringent review of these pieces of evidence would be of greater service to the reader, if more difficult to get through. This is especially the case in the last segment of the book, which reads like a "laundry list" of disorders ranging from cancer to international aggression (!), but is generaly one "success story" after another, with little evidence and no critical review of how general these phenomena are.
Many other books in press today fall into similar traps. In defense of Mr. Campbell, it should be pointed out that when he writes of "healing," he does not generally mean "improvement in physical integrity." Rather, he appears to be more concerned with emotional/spiritual well-being. Unlike many other writers, Campbell does the reader the courtesy of explicitly stating this at several points during the book. Mr. Campbell also displays more integrity than most in the disclaimer on the bibliographic inform! ! ation page: that the book, and its recommendations, are no! substitute for care by a competent trained health care professional.
Overall, then, the book is enjoyable to read, but does not succeed in building a credible scientific case for the "healing" powers of music.
