C Major Pentatonic Scale in Open G Tuning

C Major Pentatonic Scale in Open G Tuning shows the same c major pentatonic scale pitch classes across 6 strings tuned D G D G B D. The tuning changes where the same pitch classes sit across the fretboard.

Open strings and root positions

5 of the 6 open strings belong to C Major Pentatonic Scale: string 6 D (2), string 5 G (5), string 4 D (2), string 3 G (5), and string 1 D (2). 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 Pentatonic Scale on the low D string at frets 0, 2, 5, 7, and 10, saying each note name and degree aloud.
Build a phrase that lets D on open string 6 ring, then connect it to the nearest C root and two other scale tones.
Connect the C root positions on strings 6 through 1 at frets 10, 5, 10, 5, 1, and 10, adding the nearest scale tone between each pair of roots.
