Practice this tuning-specific layout

Play A Diminished 7 Arpeggio on the low G string at frets 2, 5, 8, and 11, saying each note name and degree aloud.
Build a phrase that lets C on open string 4 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 2, 7, 2, 9, 4, 0, and 7, adding the nearest arpeggio tone between each pair of roots.
