Watch the 1st Position Jangle online guitar lesson by Corey Congilio from Rhythm Factory: Texas Blues
I want to stress that even though these examples are in the boogie category they are often more of what's called a skuffle. That means, not quite straight and not quite a shuffle. I'll explain in a video why this is but for now check out this first position riff. It's similar to Open Says Me but, simpler in that there is no riff. This example will be easily translated to other grooves.
