Open strings and root positions

4 of the 7 open strings belong to B Minor Blues Scale: string 6 D (b3), string 3 F (b5), string 2 A (b7), and string 1 D (b3). None of those open-string tones is the B root, so the root must be fretted on every string.

Practice this tuning-specific layout

Play B Minor Blues Scale on the low G string at frets 2, 4, 7, 9, 10, and 11, saying each note name and degree aloud.
Build a phrase that lets D on open string 6 ring, then connect it to the nearest B root and two other scale tones.
Connect the B root positions on strings 7 through 1 at frets 4, 9, 4, 11, 6, 2, and 9, adding the nearest scale tone between each pair of roots.
