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 book also includes access to audio files online. The files include playback options to assist students in practice.
