I think this is an earth-shaker! The short summary is that it's a very thorough and detailed investigation of the interrelationships between tuning and timbre. Both at a theoretical and practical level. And I say theoretical and practical both in the musical and psychoacoustic senses of the words. It comes with a CD of auditory illustrations of the phenomena he describes. You essentially hold the CD on pause as you read the book, and when you get the cue from the text, you hit the play button for that particular band. The book opens with a really killer illustration, I think: After quoting several "authoritative" comments about how fundamental the octave is to our ears, he shows how easy it is to construct an only slightly contrived-sounding timbre that makes an exact 2:1-frequency-ratio octave sound utterly horrendous, and 2.1:1 ratio sound as though it were an octave! I haven't read it cover-to-cover yet, but two things are apparent to me from what I have read about it: 1. This book is one of a very few I've read that very clearly breaks basic new ground in the field of unusual tunings. 2. This book brings together the all-too-often separated fields of just intonation and temperament into a realm where they can be related to one another on equal terms.
