Watch the Major Blues Harmony online guitar lesson by TrueFire from Play Jazz Guitar 4: Rhythm Principles
Frank Potenza presents major blues harmony concepts in this section. He'll cover shell voicings, extensions, turnarounds, two-fives, backcycling tritone substitutions and other key concepts you need to be familiar with as you develop your comping skills.
TIP! Being a good rhythm guitarist starts with having a good sense of timing and being able to play in the pocket. But once you have a good handle on that, then you need to expand your options - both rhythmically and harmonically.
A great way to do this is by listening to other players who are great rhythm guitarists. Hear how they apply different variations and make note of what their choices are.
It helps to break your rhythm practice into those two areas - work on rhythm variations and different feels and grooves. Then work on using other harmonic options, different chord inversions and voicings. If you systematically experiment with testing out other options you will naturally gravitate towards the ones that are YOUR style, and you can further develop those, and then you will become that hip rhythm player that other people listen to!
