This is a lick taken from “Bright Lights Big City” by Jimmy Reed. The thing that is interesting is that we are playing in 1st position.
Notes in the 1st position blues scale
7 blow, 8 blow bend, 9 draw, 9 blow bend, 9 blow, 10 whole stop blow bend, 10 blow
Really take some time practising hitting those blow bends. They are not easy and take a little bit of practice. The key is to be quite gentle and try picturing yourself whistling to hit them.
