While this book was designed for college classes in functional piano, it can easily be used by any high school student who is able to sight-read simple melodies. Part 1 presents clear explanations of the functions of primary and secondary triads, dominant sevenths and secondary dominants, and modulation. Suggestions for developing facility in harmonizing in various free styles rather than the more formal chorale style are also included. Part 2 contains 797 melodies carefully selected and classified to include a variety of keys, chords, rhythms, and accompaniment styles.
