Open strings and root positions

4 of the 6 open strings belong to Ab Locrian Scale: string 6 Ebb (b5), string 4 Ebb (b5), string 2 Cb (b3), and string 1 Ebb (b5). None of those open-string tones is the Ab root, so the root must be fretted on every string.

Practice this tuning-specific layout

Play Ab Locrian Scale on the low D string at frets 0, 2, 4, 6, 7, 9, and 11, saying each note name and degree aloud.
Build a phrase that lets Ebb on open string 6 ring, then connect it to the nearest Ab root and two other scale tones.
Connect the Ab root positions on strings 6 through 1 at frets 6, 1, 6, 1, 9, and 6, adding the nearest scale tone between each pair of roots.
