Today's lick is a fast, fluid-sounding legato run based on the D Dorian mode (D E F G A B C), courtesy of Gus G. I rely on consecutive hammer-ons and pull-offs to articulate many of the notes and use finger slides to seamlessly shifts positions as I ascend the fretboard. Using finger slides allows me to continue up a single string without having to interrupt my smooth, legato phrasing with an unwanted pick attack.
