Unfortunately, this is one of those books that sounds like a great idea, but ultimately falls flat. What could be more awesome than a history of science as told through the evolution of music? Well, that'd be swell if that was actually what was accomplished here. Instead, what you get is (mostly) science, whose sections are largely rehashes of history-of-science stuff that you could read in any general work on the subject and some sporadic and awkwardly-situated bits on music that actually fare well in work as a whole.
Levenson darts from Pythagoras to the early roots of musical theory, which is nice, and then segues into a bit on organ-making and scientific advances. However, the two themes veer apart quickly with long and unnecessary sections on telescopes and microscopes with flaccid attempts to link all that to Gregorian chant, Bach, and Beethoven's bad moods. Eventually, realizing that his main idea doesn't have much to stand on, the author discusses Stradivari and the mystery of his instrument making before careening once more into a weird discussion of Poincare and the collapse of Newtonian physics...? And mice injected with AIDS. Oh yes. We can't forget the mice with AIDS. And Varese. And Theremin.
Not sure how to end this, so I'll just leave it there...
