Books in Brief. - 'Temperament: The Idea That Solved Music's Greatest Riddle' - book review
What do Pythagoras, Euclid, the 2nd-century b.c. Chinese thinker Huai Nan Tzu, Boethius, Giotto, Descartes, Shakespeare, Newton, Kepler, Rousseau, and contemporary composer Philip Glass have in common? Stuart Isacoff -- pianist, composer, and founding editor of Piano Today -- has woven them into a magnificent story about a great shift in the musical world that took place across centuries and engaged the attention of the Church, the academy, and every branch of the humanities. There are some things that seem so natural, so well established, that we cannot imagine them being any other way. Such is the case with temperament -- the way pianos (and other keyboard instruments) are tuned and how music sounds to our ear.
