Scales and arpeggios are the backbone of confident, polished playing. Practicing these two pillars of technique develops dexterity and speed. When combined with essential music theory patterns, the result is “harmony in motion.” Not just a reference for technical progress, Scale and Chord Book 3 encourages a focus on touch and sound, especially the feel of the black keys under the hands. Late intermediate and advancing students learn to perform multi-octave scales and arpeggios with fluency. Transposition exercises emphasize understanding of tonic, dominant, and leading tone. Gestural marks direct the integration of wrist motion. And, importantly, study of chord progressions provides the toolset for analysis, improvisation, and composition.
