Watch the Comping on a Raised 9 online guitar lesson by TrueFire from Play Jazz Guitar 6: Soloing Approaches
Comping on a Raised 9 - Lesson 2:3 is a video guitar lesson presented by Larry Carlton and is sourced from 335 Improv.
Now let's take what we've just learned about shifting around those raised-9 and triad shapes, and put them in context of a groove. As you first experiment with your own comping, you may want to play one chorus using strictly the 7#9 shapes, and then try another chorus with the triads. Once you're comfortable, see how great it sounds to mix and match the two.
While the 7#9 chord will function the same way every step-and-a-half, that doesn't mean that you can't leapfrog over one position to the next. You can also slide in and out of position, add upper partials, arpeggiate one and hit the next one hard... there are so many possibilities. And remember, all based on a single 7#9 chord.
