Open strings and root positions

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