Continuing the expansion of note-reading skills begun in Levels 1A-2A, this book includes melodic and harmonic 7ths and octaves to aid the student with moving freely around the keyboard. New items include the introduction of C and G major scales, as well as three-note V7 chords in C and G. Dotted quarter and eighth-note rhythm patterns are added to other rhythms of gradually increasing complexity. Each piece on the CD was recorded at a performance tempo and a slower practice tempo.
