The course's first visual model: break the major scale into overlapping three-note fragments. There are really only three shapes — whole-whole (on degrees 1/4/5), whole-half (2/6), and half-whole (3/7) — and once you know which sits under your index finger, you can run the scale up and down a single string by shifting between them. Then the fun part: reorder the notes into melodic sequences so the scale starts to sound like music instead of an exercise. One tiny idea spins into tens of thousands of practice variations — a tab PDF is included, but inventing your own is the whole point.
