Get the fretboard knowledge that makes the rest of the module click. You'll learn the movable octave shape (two strings and two frets up), then the "warp" — the dividing line between the G and B strings where standard tuning narrows to four frets, shifting any pattern that crosses it one fret toward the bridge. That sets up the minor pentatonic "stack": the compact six-note shape, well worth memorizing, that you'll picture and play all over the neck, with its root the higher note on the middle string.
