Open strings and root positions

3 of the 7 open strings belong to Bb Locrian Scale: string 6 Fb (b5), string 2 Cb (b2), and string 1 Fb (b5). None of those open-string tones is the Bb root, so the root must be fretted on every string.

Practice this tuning-specific layout

Play Bb Locrian Scale on the low A string at frets 1, 2, 4, 6, 7, 9, and 11, saying each note name and degree aloud.
Build a phrase that lets Fb on open string 6 ring, then connect it to the nearest Bb root and two other scale tones.
Connect the Bb root positions on strings 7 through 1 at frets 1, 6, 1, 8, 3, 11, and 6, adding the nearest scale tone between each pair of roots.
