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. This package includes both a Piano Lessons book and CD featuring wonderful tracks to accompany the student during practice or performance.
