Practice this tuning-specific layout

Play D Dominant 9 Arpeggio on the low A string at frets 0, 3, 5, 7, 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 D root and two other arpeggio tones.
Connect the D root positions on strings 7 through 1 at frets 5, 10, 5, 0, 7, 3, and 10, adding the nearest arpeggio tone between each pair of roots.
