Watch the Train Vamp online guitar lesson by David Hamburger from 30 Beginner Fingerstyle Blues Licks You MUST Know

This lick is built on two fundamental blues tools, the quarter-tone bend and the double stop. A quarter tone bend is a bend that raises a note only half as far as a half-step or one-fret bend – in other words, to a note that falls between the frets, one you can't even get to without bending. A double stop just means playing two notes at once, most often on adjacent strings.
