Watch the G Shuffle online guitar lesson by Larry Carlton from 335 Blues

A major part of the rhythm player's job description is to support the soloist. We want the soloist to know that he can rely on the rhythm section, not just for keeping good time but for feeding him ideas.
I'll demonstrate three choruses of comping here in this shuffle, in the key of G. Each has a different approach, and you'll notice how they progress nicely from one chorus to the next.
The first chorus has a kind of pulsing energy to get the soloist started, and it's rock solid because parts of it lock in with the bass.
In the second chorus, classic blues voicings ride along on top of the bass part, providing new rhythms and some harmonic possibilities for the soloist to sink his teeth into.
For the last chorus, I opted to give the soloist a lot of space. With big gaps between rhythm stabs - and a dependable comping part that keeps coming back around - the soloist has a lot of room to cut loose.
