Open strings and root positions

3 of the 6 open strings belong to A Diminished 7 Arpeggio: string 6 C (b3), string 4 C (b3), and string 2 C (b3). None of those open-string tones is the A root, so the root must be fretted on every string.

Practice this tuning-specific layout

Play A Diminished 7 Arpeggio on the low C string at frets 0, 3, 6, and 9, saying each note name and degree aloud.
Build a phrase that lets C on open string 6 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 9, 2, 9, 2, 9, and 5, adding the nearest arpeggio tone between each pair of roots.
