An excerpt from the Preface.
This work supplies a new and vital element in musical culture. It is not Harmony study alone, as generally understood, for it differs in many respects. Some of its unique features are:
(1) Keyboard Work. In order to make the work practical for teachers and performers, much attention is given to the formation and use at the keyboard, of the various Intervals, Chords, Cadences and other progressions including also Improvising, Modulating and Transposing. With the aid of the Keyboard Diagram this also becomes possible in Harmony class work.
(2) The Replacing of the Numberless Rides for Part-writing by a few broad principles, which explain both rules and exceptions.
(3) The Classification of the Chords of the Dominant Seventh, Major and Minor Ninth, Diminished Seventh and the three forms of the Augmented Sixth, as Only Slightly DIFFERING FORMS OF ONE AND THE SAME HARMONY, simplifying wonderfully these more complicated chords.
(4) "The Principle of Tendencies," which explains many of the perplexing things in Musical Theory, and simplifies the subject wonderfully.
(5) The "Attendant Chords," which make many foreign harmonies clear.
(6) Modulation, presented in a very simple and practical form.
(7) Studies in Analysis and Ear-training, with hints on Improvising.
(8) The Knowledge of the Underlying Principles of Acoustics, Musical Structure and Tone Relations, which explain most of the mysterious things about which many trained musicians are unenlightened.
(9) The Use of the "Sharpest Note" as a means of analyzing foreign chords, which is a revelation to most musicians.show more
