Book excerpt: "Prompted by controversial views of the composer-theorist Jean-Philippe Rameau, the leading figures of the French Enlightenment engaged in a vigorous philosophical debate about the nature of music. Their dialogue was one of extraordinary depth and richness, and dealth with some of the most fundamental issues of the French Enlightenment. In the newly revised edition of 'Music and the French Enlightenment', Cynthia Verba updates this fascinating story with the prolific scholarship that has emerged since the book was first published." -- rear cover.
