Watch the Bebop Comping online guitar lesson by Sheryl Bailey from Bebop Dojo: Essentials
All the great jazz guitarists use these shell voicings and this four to the bar type of comping. With these shapes you can work on your rhythm guitar chops on any standard tune and you can start to get into real playing situations. Also it will help your single note playing because you will have a strong sense of the pulse. This revolves around working with the metronome on beats 2 and 4 to give those beats a push, or bounce. The feeling of that bounce is the foundation of a strong swing feel.
