While the other reviewers here are correct in noting many errors and misinterpretations in this little book, I wanted to insert what I think is useful information about the nature of the book, especially what audience the author seems to address. I bought this book as one of the required texts for a grad course in music perception and cognition the year it came out (92). Looking at it now, it definitely does not seem to be the best book for that context, but I think the professor may have wanted the class to have an easy read that introduces concepts rather than focusing on specifics. (The course had plenty of readings of anatomical and psychological studies and the like.)
In looking back at this book, I realize how easy it is to read, and how the author is able to address basic acoustical concepts in a relatively thorough and comprehensible way. His writing style is largely informal, yet inviting. It's certainly not intended as an authoritative science book, but it covers a broad range of subjects at an introductory level. For example, there is a chapter on "Perception, Illusion, and Effect" that is a mere 15 pages long, including illustrations.
This book is for people who want a basic, relatively thorough, well-explained education in musical acoustics, and who can tolerate a few errors in exchange for an easily understood big picture perspective.
