Practice this tuning-specific layout

Play A Diminished Arpeggio on the low C# string at frets 2, 8, and 11, saying each note name and degree aloud.
Build a phrase that lets Eb on open string 1 ring, then connect it to the nearest A root and two other arpeggio tones.
Connect the A root positions on strings 6 through 1 at frets 8, 1, 8, 3, 11, and 6, adding the nearest arpeggio tone between each pair of roots.
