Play D Major Blues Scale on the low G string at frets 2, 4, 7, 9, 10, and 11, saying each note name and degree aloud.
Build a phrase that lets D on open string 6 ring, then connect it to the nearest D root and two other scale tones.
Connect the D root positions on strings 7 through 1 at frets 7, 0, 7, 2, 9, 5, and 0, adding the nearest scale tone between each pair of roots.
