(Educational Piano Library). Piano Technique Book 5 expands the skills emphasized in Piano Technique Book 4 . Through engaging Warm Ups and Etudes, students are encouraged to explore diatonic and chromatic scales, chords, inversions, and chord progressions. The exercises also focus on important, intermediate level skills: finger substitutions, extended and contracted hand positions, grace notes, playing a waltz bass, and refinement of articulation and coordination. Each Warm Up and Etude has its own original accompaniment, available on a separate CD or GM disk. The exercises in this book are carefully correlated to the music in Piano Lessons Book 5 .
