The Level 2B Lesson Book of Premier Piano Course continues the expansion of note-reading skills begun in Levels 1A, 1B and 2A and 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.
