Practice this tuning-specific layout

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