Query: Toots his horn too much

I was looking for a book to enrich my knowledge of acoustics and musical instruments. Having a BS in mechanical engineering, I am not a stranger to differential equations, but I don't particularly want to spend my leisure time solving them. This book is not for someone like me. This book is for someone who wants to read a novel about musical acoustics. Physical descriptions are not concise, but rife with draw out analogies. The ideas are miles apart. After having read a good deal of technical material I have come to expect a certain cold precision in descriptions of physical phenomena. This book doesn't deliver what I wanted. Now I get to decide if it is really worth the effort of extracting whatever knowledge I can.
