Practice this tuning-specific layout

Play C Diminished 7 Arpeggio on the low A string at frets 0, 3, 6, and 9, saying each note name and degree aloud.
Build a phrase that lets Bbb on open string 7 ring, then connect it to the nearest C root and two other arpeggio tones.
Connect the C root positions on strings 7 through 1 at frets 3, 8, 3, 10, 5, 1, and 8, adding the nearest arpeggio tone between each pair of roots.
