Practice this tuning-specific layout

Play C Major Blues Scale on the low G string at frets 0, 2, 5, 7, 8, and 9, saying each note name and degree aloud.
Build a phrase that lets G on open string 7 ring, then connect it to the nearest C root and two other scale tones.
Connect the C root positions on strings 7 through 1 at frets 5, 10, 5, 0, 7, 3, and 10, adding the nearest scale tone between each pair of roots.
