Practice this tuning-specific layout

Play C# Dominant 9 Arpeggio on the low A string at frets 2, 4, 6, 8, and 11, saying each note name and degree aloud.
Build a phrase that lets B on open string 2 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 4, 9, 4, 11, 6, 2, and 9, adding the nearest arpeggio tone between each pair of roots.
