The Scale is an all-important handbook designed to aid musicians and composers in gaining an understanding of the time-honored principles of harmony in music. The book describes how these principles had been misapplied during the 20th century and how they can now be reapplied to restore music to its former greatness and glory. In this revolutionary work, the author not only carefully describes the immutable laws of natural harmony, recognized by the great minds of ancient times, but also presents his own revolutionary discoveries that will help lay the groundwork for music in the 21st century.
