Open strings and root positions

4 of the 7 open strings belong to C Major 7 Arpeggio: string 6 E (3), string 3 G (5), string 2 B (7), and string 1 E (3). None of those open-string tones is the C root, so the root must be fretted on every string.

Practice this tuning-specific layout

Play C Major 7 Arpeggio on the low A string at frets 2, 3, 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 3, 8, 3, 10, 5, 1, and 8, adding the nearest arpeggio tone between each pair of roots.
