Module 1 kept you inside one box; here you open up the whole neck. You'll learn the major pentatonic scale as the same stack shape with a new root, memorize the A notes the way you did E, and connect stacks into long diagonal "octave pathways" that let you solo across three octaves without ever leaving the pentatonic scale. By the end you're improvising over an A7 vamp in both major and minor — and a bonus lesson uses a freeze pedal to train your ear to hear exactly how each note sits against the chord.
