Watch the Denying the V online guitar lesson by Richard Van Bergen from 50 Down Home Blues Licks You MUST Know
A slight variation in the way you play a lick or accompaniment can be the difference between gettin’ close and the real thing. This rhythm pattern in E is an example of this. The basis of this V to IV to I accompaniment is a very common, often used pattern. Figuring out Lazy Lester and Jimmy Reed records I always had the idea my playing lacked something. Why do I sound so different? Finally I got it! On the V and IV chord you play an A bass note. This adds a certain tension to it and makes it sound real down-home. In his autobiography Keith Richards has an in depth discussion about this.
