How Equal Temperament Ruined Harmony (and Why You Should Care) First Edition
A captivating look at how musical temperament evolved, and how we could (and perhaps should) be tuning differently today.
Ross W. Duffin presents an engaging and elegantly reasoned exposé of musical temperament and its impact on the way in which we experience music. A historical narrative, a music theory lesson, and, above all, an impassioned letter to musicians and listeners everywhere, How Equal Temperament Ruined Harmony possesses the power to redefine the very nature of our interactions with music today.For nearly a century, equal temperament―the practice of dividing an octave into twelve equally proportioned half-steps―has held a virtual monopoly on the way in which instruments are tuned and played. In his new book, Duffin explains how we came to rely exclusively on equal temperament by charting the fascinating evolution of tuning through the ages. Along the way, he challenges the widely held belief that equal temperament is a perfect, “naturally selected” musical system, and proposes a radical reevaluation of how we play and hear music.

I got the feeling Duffin was really fired up to rebut Stuart Isacoff's "Temperment" published awhile back that asserted the Temperment Wars were largely settled by Rameau's time. Isacoff, in addition to being a writer is a pianist, which may make him suspect in Duffin's view.
Fair enough and Duffin's prose is much more pleasant to read than Isacoff's, but beneath the surface, "How Equal Temperment Ruined Harmony" is often circumstantially argued, stuffed to the gills with filler bios (I don't care that Duffin acknowledges the Oxford Dictionary - they deserve co-authorship if not co-royalty for taking up so many pages). And the cartoons are by and large awful and unneccessary. They make the typical Dummies cartoons look like the New Yorker by comparison.
Beyond this Duffin is no doubt a knowledgable and passionate advocate for his view.
He's not asking musicians to abandon "ET" (good luck with that), but instead asking them to broaden their range of intonation possibilities and understand why and when a varied approach to melodic and harmonic adjustment may yield surprising and satisfying results. In asking us to be open and experiment the book serves a purpose. When Duffin implies "try it and you'll never go back", he comes across as somewhat less than open-minded.
I had a general problem with Duffin's tone, which frequently condescends. He seems at times to assert that no one other than himself is in on this long-lost secret wisdom. It might just surprise him to discover that many non-classical musicians are just as sensitive to and deal with intonation issues - even some of us hopelessly mal-intonated players of fretted instruments.
Duffin raises historical questions that are valid, interesting and worth contemplating by all musicians. Unfortunately, many of them can never be definitively answered. Did the tuning system begat the music or did the evolution of musical practice toward greater chromaticism gradually shape the systems? Did the massive popularity of the piano in the nineteeth century as the symbol of middle class culture unduly "mis-condition" generations of naive music lovers into blanket acceptance of the artificial equal termperment? With the overwhelming majority of (western) music possessing both melody and some form of harmony, is Duffin's purist approach really feasible for all but the solo performer?
All interesting ideas worth considering and a good read (and fairly quick if you skip the boring bios).
One reason I like this book is because it puts the "purists" in their place---the people who think Schoenberg is terrible and so on---dopes that think that only traditional harmony gets the stamp of approval from Gawd! These ultimate judges of what is right and wrong might very well dislike Bach if they heard his music in it's original state.
In any case, I love facts that shake up the cobweb laden, old curmudgeon classical zombies that just hate music that they can't comfortably sip wine to.

Why do I say it's terrible? The book is your quintessential word-salad, commonly wrote by those in "higher academia", where the author never wants you to forget they also possess extensive knowledge on fine scotches and vintage wines, never failing to exhaust lofty vocabulary to ensure the fact.
The book offers informative, yet mostly useless for pertinence, backstories about the characters, their families,etc; splashing them crudely amongst the immediate point, when such inserts should've been catalogued at the rear...if at all; it's entirely distracting but perfectly suits the overall weak form of this opinion piece.
Why would I recommend you buy it? Three reasons: 1) you may very-well enjoy the self-flagellating style the author enjoys; it's the perfect book to sit at home and read... because no-one wants you at their parties.
2) I believe that sometimes, even if not enjoyable, an experience might help make more sense of something confusing you.
3) This is the most useful part of the book: it's absolutely abundant with references that could lead you to further explanation of the topic of tuning.
So, yes, buy the book (though try to get it as cheap as possible), but don't expect it to provide you any conclusive answers; it's just not that good in that regard, the book completely lacks the amount of sufficient clarity, diagrams, cross-examples, etc, to assure the ready completely fathoms the scope. This book is best suited to someone who's already well-versed on the various talking points, yet wants to read someone's insight on the topic.
