Book 6 of Sight Reading & Rhythm Every Day® reinforces previous skills and adds new skills such as reading sixteenth-note rhythms in several different keys and includes combinations of rhythms such as an eighth note followed by two sixteenth notes and a dotted eighth note followed by two sixteenth notes. Also introduced are diminished triads, augmented triads, dominant seventh chords and their inversions. Students further their skills in harmonization and are provided with necessary sight-reading and rhythm drills and "flash" exercises to hone their sight-reading skills.
