A Persian scale

Five shapes, each anchored to a chord form you already know, the pop and rock default that ties your scales to your chords. The outlined notes are that chord, so you can see the C, A, G, E, and D shapes inside the scale.

3NPS stands for 3 notes per string. It lays the scale out in seven even shapes for rock and metal lead, and favors speed because the picking pattern stays consistent across every string.

7 four-fret boxes, one per scale degree, each a single hand position with almost no shifting. The jazz and classical way, from William Leavitt's Berklee method.
