Practice this tuning-specific layout

Play C Dominant 9 Arpeggio on the low D string at frets 0, 2, 5, 8, and 10, saying each note name and degree aloud.
Build a phrase that lets D on open string 6 ring, then connect it to the nearest C root and two other arpeggio tones.
Connect the C root positions on strings 6 through 1 at frets 10, 5, 10, 5, 1, and 10, adding the nearest arpeggio tone between each pair of roots.
