A7 Punctuation is a video guitar lesson presented by 30 Penta Sonic Blues Licks You MUST Know

A minor pentatonic box pattern #3.
This lick is almost too much fun to play, but don't let that stop you! With the B string getting almost all the attention, you'll be playing some up tempo triplets.

You're starting on the 10th fret of the G string, going up to the 11th fret using your 2nd finger, and here you'll hit the ground running, on the G string going from the 10th fret to the 12th fret, on to the 13th fret, and back to the 10th then repeating that two more times before you get back to the G string 11th fret with your 2nd finger. Lastly, go back up to the B string 10th fret with your index finger bending that root note a 1/4 step and tag the A7 chord.
