Watch the The Vamp online guitar lesson by TrueFire from Play Blues Guitar 7: Fingerstyle Approaches
The Vamp - Performance is a video guitar lesson presented by David Hamburger and is sourced from Essentials: Fingerstyle Blues.
Each two-bar phrase in The Vamp is basically a one-bar minor pentatonic lick over a steady bass followed by a one-bar vamp figure. Four of these two-bar figures make up the first 8-bar section, which we'll call the "A section”. Repeating this first section with a slight variation makes up the next section, or "second A,” and taking the fourth lick from these first two sections and playing some variations on that makes up the concluding or B section.
