Watch the I Chord: D1 online guitar lesson by Mark Stefani from Jazzed Blues Assembly Lines

Segment four showcases another classic keyboard double-stop lick, translated to guitar. This two-bar phrase, again dedicated to the C7 chord, sees the high root maintained while a popular, chromatic blues lick takes place below it. A quick left-hand shift gets you into the traditional bar position (8th fret) for more double-stops and interplay between the C and Bb. This lick is highly versatile, and can potentially be transposed to fit both the IV (F7) and V (G7) chords in any blues progression.
