Editor’s notes

After checking out the song “Blue on Black” (Kenny Wayne Shepherd) upon viewer request, I immediately found myself nodding my head to this main riff heard throughout the song – so I wanted to make this lesson teaching you how to play it. It uses only three chords (I’m staying in standard tuning), but has plenty of small opportunities to add distinctive flourish. Use of a D-power chord, hammer-ons, walking bass notes, and more make this quite fun to pick up and play whenever you’re looking for a quick warm-up exercise.

Chords needed

Big picture, the three chords you’ll need for this exercise are D5, Cadd9, and G. The most important thing note with these three chords is that your left ring finger will be on the 3rd fret of the B-string (2nd string) for each chord shape. This makes switch way easier.

E |–––2––––3––––3–––
B |–––3––––3––––3–––  <== left ring finger is on 3rd fret of this string
G |–––2––––0––––0–––      for all of these chords. Keep it planted there!
D |–––0––––2––––0–––
A |––––––––3––––2–––
E |–––––––––––––3–––
      D  Cadd9  D

Learning the D5 chord

For the D5 chord, here’s a comparison to a typical D-major chord. The goal with the D5 is to not play the thinnest (high E) string. If you can, the ideal is to mute it (by lightly letting one of your left-hand fingers touch it, but not press it down). This will let you strum it as part of the chord, but have it not make a sound.

E |–––2–––  <== left middle finger     E |–––––––  <== don't play this string!
B |–––3–––  <== left ring finger       B |–––3–––  <== left ring finger
G |–––2–––  <== left index finger      G |–––2–––  <== left index finger
D |–––0–––                             D |–––0–––
A |–––––––                             A |–––––––
E |–––––––                             E |–––––––
      D                                      D5

Chord changes

When you start to put it all together, first understand when the big changes are happening. Specifically, you’ll have four counts of D5 followed by Cadd9 (1.5 beats) and G (2.5 beats). It’s the G chord that’s coming an eighth note ahead of the quarter note beat.

E |––––––––––––––––––––––––––––––––––|––3–––––––––––3––––––––––––––––––|–
B |––3–––––––––––––––––––––––––––––––|––3–––––––––––3––––––––––––––––––|–
G |––2–––––––––––––––––––––––––––––––|––0–––––––––––0––––––––––––––––––|–

E |––––––––––––––––––––––––––––––––––|––––––––––––––3––––––––––––––––––|–
     D5                                 Cadd9       G
     1 e + a 2 e + a 3 e + a 4 e + a    1 e + a 2 e + a 3 e + a 4 e + a
     v                                  v           v

Add strumming

From there, you can start to fill it out a bit by adding single down strums on each quarter note count. This is a good way to get comfortable with the overall groove before you start adding the additional flourish.

E |––––––––––––––––––––––––––––––––––|––3–––––––3–––3–––––––––––3––––––|–

     1 e + a 2 e + a 3 e + a 4 e + a    1 e + a 2 e + a 3 e + a 4 e + a
     v       v       v       v          v       v   v           v

Strumming w/ a lead-in bass note

A skill that is used in two different places in this riff is that of strumming the bass note of the chord (on the 1 count) and then strumming the rest of that same chord on the “+” count that follows. Here are two ways to play this, shown for the Cadd9 and the G chord. A good practice tip is to play either of these in a cycle, over and over, until you’re comfortable with it. That will make it easy to execute when you need to use it in the main riff.

E |––––––3–––––––––––        E |––––––3–––––––––––
B |––––––3–––––––––––        B |––––––3–––––––––––
G |––––––0–––––––––––        G |––––––0–––––––––––
D |––––––2–––––––––––        D |––––––0–––––––––––
A |––3–––––––––––––––        A |––––––2–––––––––––
E |––––––––––––––––––        E |––3–––––––––––––––
     Cadd9                        G
     1 e + a 2 e + a              1 e + a 2 e + a
     v   v                        v   v

Put it all together!

From there, you’ll have many of the specific building blocks you need to play this full riff. Good luck with it! Let me know if you have any questions.
