Technique 4 continues and expands on the technical and artistic tools learned in Technique books 1A - 3. The five new Technique Tools introduced are: staccato against legato, playing in and out of black keys, speed links, open the hand, and rock the Alberti bass. Artistic Etudes showcase a student's technique in an expressive musical setting, and Hands-Together Workshops focus on developing the skills necessary for coordinating hands-together playing. Masterwork Etudes provide training to play standard masterworks. Each page in the Technique Book correlates with a specific page in the Lesson Book.
