Practice this tuning-specific layout

Play Ab Major Blues Scale on the low B string at frets 0, 1, 4, 6, 9, and 11, saying each note name and degree aloud.
Build a phrase that lets Cb 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 9, 4, 11, 6, 2, and 9, adding the nearest scale tone between each pair of roots.
