The hallmark of the revised Level 3B Theory Book is the synthesis of 3B concepts: major and minor scales, triads and chord inversions, and 16th-note rhythms are reinforced with writing, composing, sightreading, and ear-trainingexercises. Students will enjoy composing a tune for a lead sheet, harmonizing melodies, identifying triad inversions, and creating their own 16th-note rhythms in various time signatures.
