Open strings and root positions

6 of the 7 open strings belong to Bb Major Pentatonic Scale: string 7 G (6), string 6 D (3), string 5 G (6), string 4 C (2), string 3 F (5), and string 1 D (3). 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 Major Pentatonic Scale on the low G string at frets 0, 3, 5, 7, and 10, saying each note name and degree aloud.
Build a phrase that lets G 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 3, 8, 3, 10, 5, 1, and 8, adding the nearest scale tone between each pair of roots.
