Title: On the other hand, there's Duffin.
Review: Readers of this book would be well served by also reading Ross Duffin's "How Equal Temperament Ruined Harmony (And Why You Should Care)". It covers most of Isaacson's "blind spots" and, as the title suggests, takes quite a different view of the subject. Duffin has a great mastery of the historical evidence and writes in a very accessible style--no heavy mathematics needed, though some elementary musical knowledge would be helpful.
