Watch the Swing Blues online guitar lesson by Henry Johnson from Jazz Expressions
Let's break down some of the things I just did. This was a blues taking advantage of all the areas of activity using an F7 inversion, going up through them all and back down. We'll be taking advantage of the pentatonic here to really draw out the bluesy feeling.
In the second chorus, I started to play with the rhythm a little bit more, and we're keeping it bluesy but adding in some chromatic ideas. Another thing that I did is used a pull off at the last minute to make it come off different than usual. This adds a nice rhythmic variety to the solo. You can also change things up by playing in half time, even though everyone else is playing 4/4.
