The scale most closely associated with dominant seventh chords is Mixolydian; in G, G Mixolydian is spelled GABCDEF, with B as the major third. The minor third is one half step lower, Bb; this pitch can also be thought of as the b9 (flatted ninth). In bar 1 of the solo, I begin on beat one by hammering on from the minor to the major third, and, on beat two, incorporate both the minor and the major third. Be aware of the difference in quality between these intervals and try to take advantage of that difference while crafting your solos.
