(Educational Piano Library). Book 4 expands on the related five-finger patterns learned in Book 3 to introduce the scales of C Major, A Minor, G Major, and E Minor. Chord progressions in close position are also presented in each of these keys. Syncopated rhythms, syncopated pedaling and opposing articulations between the hands create performances with style, color, and texture. | Piano Lessons Book 4 by Fred Kern, Paperback | Indigo Chapters
