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 pedalling and opposing articulations between the hands create performances with style, colour, and texture. The package includes both a Piano Lessons book and CD featuring wonderful tracks to accompany the student during practice and performance.
