Practice this tuning-specific layout

Play C# Diminished 7 Arpeggio on the low A string at frets 1, 4, 7, and 10, saying each note name and degree aloud.
Build a phrase that lets E 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 7 through 1 at frets 4, 9, 4, 11, 6, 2, and 9, adding the nearest arpeggio tone between each pair of roots.
