Here we have a riff that follows the notes of a minor pentatonic scale. If you are unsure of what that is, there are several tutorials available that will help you get the grasp of it. For this lesson, its not entirely necessary to know; though, it would be useful when trying to improvise your own version of this example.
Feel free to play around with making notes staccato, and be sure to experiment lots with the opposite characteristic: legato.
Have some fun with the bends-- try doing a 1/2 tone bend, vs. a 1/4 tone, etc, etc.
When you feel comfortable with this example, move on to the next, for a slight variation.
