Temperament: The Idea That Solved Music's Greatest Riddle

With the existing literature tending to bog down in mathematical theory or historical tuning methods, Isacoff bravely attempts to make this seemingly arcane topic interesting to the general reader. He distills the mathematics and music theory into their simplest essences, and draws apt analogies from the everyday. He also generously peppers the text with the quirks and escapades of its more flamboyant central characters; the relevance of the information is often tenuous at best, but Isacoff has obviously done his homework, and he can be forgiven some frivolity.

Less forgivable is his neglect of "well-temperament." Namesake of Bach's masterful collection of 24 pieces (one each in all the major and minor keys), the well-tempered keyboard liberated composers from the howl of badly tuned keys in the way equal temperament did, while preserving the distinct quality of each key. It was a pragmatic and aesthetically rich solution that captivated composers and theorists for decades. Yet Isacoff reserves less than two pages for its description. (Perhaps he deliberately overlooked the topic since it doesn't fit well with his casting of equal temperament's opponents as rigid, dogmatic, and impractical.)

Despite its flaws, Temperament is an accessible guide to a fascinating topic seldom discussed outside musical circles. Though the book may not invigorate hard-core theorists, the amateur musician, armchair scientist, history buff, or plain old curious can glean plenty from it. The advent of digital keyboards--some of which can be tuned to historical temperaments at the flip of a switch--makes this an ideal time for the topic to be rejuvenated. --Todd Gehman

Product Description
A fascinating and hugely original book that explains how a vexing technical puzzle was solved, making possible some of the most exquisite music ever written.

From the days of the ancient Greeks, the creation of music was thought to be governed by divine and immutable mathematical certainties. But over time skeptics came to understand that those rules limited harmonic possibilities. In Temperament, we see the traditionalists and the innovators battling across the centuries, engaging great thinkers like Newton, Kepler, and Descartes as well as musicians, craftsmen, church leaders, and heads of state. At the heart of their dispute is the question of how the tones of a musical scale should be selected.

The breakthrough came in the eighteenth century, when the modern keyboard was given perfect musical symmetry through a tuning of equal temperament, each pitch reliably equidistant from the ones that precede and follow it. This tuning allows a musical pattern begun on one note to be duplicated when starting on any other; it creates a musical universe in which the relationships between tones are reliably, uniformly consistent--a universe of greatly expanded possibility, one that allowed Liszt, Chopin, Brahms, Debussy, and all those who followed to compose the piano music we listen to today.

Stuart Isacoff relates the story of the reinvention of the piano--a story that encompasses social history, religion, philosophy, and science as well as musicology--in a concise and sparkling narrative. Temperament is a jewel of a book.
