Open strings and root positions

2 of the 7 open strings belong to Bb Phrygian Scale: string 7 Cb (b2) and string 2 Cb (b2). 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 Phrygian Scale on the low B string at frets 0, 2, 4, 6, 7, 9, and 11, saying each note name and degree aloud.
Build a phrase that lets Cb on open string 7 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 11, 6, 1, 8, 3, 11, and 6, adding the nearest scale tone between each pair of roots.
