This lesson is a turn around. It is a little scale you can add to the start, end or even as a fill in to any bluesy type musical sentence. It is a fun and easy and goes with most of the sentences you can learn in the book Play Guitar By Ear!
The intro or exit to a musical sentence (or can even be used as a fill in) is
:

The numbers in the large picture represent the order in which they should be
played. This move is done by moving the numbers 1 & 2 fingers
(index & middle fingers) down the neck picking the notes.
(Practice and play with this your own way
- Experiment it's fun!)
Push play to listen to the sentence. (It may start on it's own.)
Now listen when you add it to a sentence. The sentence is being played on two ordinary acoustic guitars.
Be sure to
listen for the turn around at the beginning and end of the sentence.
