Practice this tuning-specific layout

Play Ab Diminished Arpeggio on the low G string at frets 1, 4, and 7, 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 arpeggio tones.
Connect the Ab root positions on strings 7 through 1 at frets 1, 6, 1, 8, 3, 11, and 6, adding the nearest arpeggio tone between each pair of roots.
