PREFACE TO THE FOURTH REVISED AND ENLARGED EDITION.
In addition to certain emendations, etc., introduced throughout the work, I have thought it well to add a chapter in which the whole subject is treated in a broad and comprehensive way in the light of the latest scientific knowledge.
In this review the psychological aspects of the subject have not been neglected, and the whole has been related to practice to as great an extent as the character of the book permits.
It is significant that on both sides of the Atlantic there is a growing conviction that the foundations for speaking and singing as an art must be made as scientific as the state of our knowledge will permit.
The Author.
