Practice this tuning-specific layout

Play C# Major 9 Arpeggio on the low C string at frets 0, 1, 3, 5, and 8, saying each note name and degree aloud.
Build a phrase that lets B# 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 1, 6, 1, 6, 1, and 9, adding the nearest arpeggio tone between each pair of roots.
