I'm rating this book with just one star because the other reviews are too good, otherwise I may give it "two stars" but no more.
I bought this book because of the positive reviews and I was sorely disappointed. I was expecting a book about the metaphysics of sound. What I got was the superficial text of a rambling enthusiast. The variety of topics covered is interesting and the style is engaging... during the first couple of chapters. After that, Berendt needs a good editor. For example, several times we find quotations of the type (not verbatim): "Some author says that the molecules of hydrogen resonate with a major third interval: <<The molecules of hydrogen resonate with a major third interval>>" This kind of quotation adds nothing and explains less. I am still wondering what kind of analogy is it they were talking about. Besides, the second part of the book consists of a few miscellaneous articles on Zen, jazz, etc., unrelated to what should be the main topic of the book.
On the good side, it showed me some threads to follow... but nothing that can't be found elsewhere, I'm afraid.
