Practice this tuning-specific layout

Play A Dominant 7 Arpeggio on the low A string at frets 0, 4, 7, and 10, saying each note name and degree aloud.
Build a phrase that lets A on open string 7 ring, then connect it to the nearest A root and two other arpeggio tones.
Connect the A root positions on strings 7 through 1 at frets 0, 5, 0, 7, 2, 10, and 5, adding the nearest arpeggio tone between each pair of roots.
