Don't get me wrong, I'm all for blues music, but the blues scale can yield beguiling musical results that bear little resemblance to the traditional blues—particularly if one looks at (and listens to) the scale from a different point of view.
Chord Creation
The idea of harmonization is relatively simple. It means is to play two or more notes together at the same time. Technically speaking, two notes performed at the same time create a dyad, not a chord. It takes three or more notes performed simultaneously to create a chord, although the one exception, the two-note so-called "power chord" in Ex. 1, skews this theory a bit.
So, which two or more notes should you harmonize? Any you want! But, if you desire continuity in your compositions and playing, it's a good idea to harmonize notes from a specific scale.
Most musicians usually start with the major scale, stacking every other note of the scale on top of each other until a triad is created (Ex. 2).
From there you can start adding, or replacing notes, to create variations from these basic triads, as seen in Ex. 3.
I must point out that you can also arpeggiate these chords, playing the notes one at a time (Ex. 4). Since we are emphasizing harmony in this lesson, it helps to let them ring out.
That's the most common way to create chords, but in this lesson we're looking for something unusual. So rather than being so formulaic, let's proceed with the basic idea that playing two or more notes at the same time will work as long as they all come from the blues scale.
The blues scale is just the minor pentatonic scale with one additional note, which gets labeled #4 or a b5 depending on context. Ex. 5 shows the most common "box" pattern for the A blues scale (A–C–D–Eb–E–G). After getting a hold of this scale, I recommend working on it in the key of E and D since many of the notes can be played with open strings.
There are two considerable disparities when it comes to generating chords from the blues scale as compared to the major scale. First, the blues scale only has six notes and second, the intervals between the notes in each scale are significantly different.
This means that the blues scale creates radical changes in chord construction and nomenclature, the theory of which is far beyond the scope of this lesson. For instance, Ex. 6 is a selection of relatively common chords you can generate from the A blues scale. Later on, we will get into more exotic harmonies.
For now, all you really need to understand about the theory is that, the chords, and the melodies I've composed to fit them, all come from harmonizing notes from the A blues scale.
When Theory, Intuition, and Creativity Meet
Once the concept of harmonization is understood, the possibilities are limited only by your imagination. The following examples are just a few of the endless ideas you could generate. I have designed my examples to imitate the styles of well-known composers and guitarists and broken them down into how they are fingered on the fretboard.
Ex. 7 is a particularly fun place to start as this arpeggio is just the A blues scale, but the notes are displaced into different octaves to create chords.
For Ex. 8 I've rearranged the notes ever so slightly to create a slightly more uniform, pseudo-Slayer progression and melody.
Ex. 8
The bent note at the beginning of Ex. 9 immediately made me think of Jimmy Page, so for guitar two, I mimicked Robert Plant's chromatic vocal melody on "Misty Mountain Hop" to create this Led Zeppelin-inspired etude. Note that the first chord is labeled A5(#11) because it contains the D# almost an octave and half higher than the root, making it a #11 in relationship to the A.
Ex. 9
Ex. 10 was a happy accident I discovered while playing around with this lesson's concept. It's unashamedly Nine Inch Nails meets Andy Summers. The second chord in the progression is a little tricky to label, so I went with D5(b9) as it contains Eb an octave and one half-step away from the root, making it the b9.
Ex. 10
Ex. 11 demonstrates the power of playing unexpected, three-note chords over a static bassline, very similar to funk/fusion keyboard players in the 1970s (think Herbie Hancock and Chick Corea). To provide continuity, I've actually harmonized the blues scale using the same method discussed in Ex. 2. The chord labels I've chosen are derived from a combination of the chords and the bass line, though you'll see there are really only two chords: Cm and Asus4, played with different voicings. And take my word for it, the fact that this progression contains both Cm and Am chords is highly unusual and worth more investigation.
Ex. 11
Ex. 12 Is a pseudo-power chord riff a la Fugazi or other bands found in the post-punk/emo genres. I've started here with a variation of the A5(#11) chord. Perhaps this is the defining chord of the harmonized blues scale? The rest of the progression seems to alternate between variations of Am and G, but notice that the bass is playing different notes over the chords, providing harmonic variation. Also pay attention that B and C sections are slightly different.
Ex. 12
Comprehend and Create!
I hope by now you've realized that the key to exploiting the harmonized blues scale is to include the #4/b5 in all your progressions. This is the vital element that distinguishes the blues scale from so many others. Make your own progressions, melodies, and songs based on what we've started here. You are only limited by your imagination.

UAFX Enigmatic ’82 Overdrive Special
uaudio.com
I’ve never played a realDumble. I’d venture most of us haven’t. But given my experiences with James Santiago’s UAFX modeling pedals, most recently theUAFX Lion, I plugged in the new Dumble-inspired UAFX Enigmatic confident I’d taste at least the essence of that very rare elixir. You could argue there is no definitive Dumble sound. Each was customized to some extent for the customer, and they are renowned nearly as much for dynamic responsiveness and flexibility as their singing, complex, clean-to-dirty palettes.
The Enigmatic nails the flexibility, for sure. To my ears, its tone foundation lives somewhere on a sliver of Venn diagram where a black-panel Fender and a 50-watt Hiwatt intersect. It’s alive, dimensional, snappy, sparkly, massive, and, at the right EQ settings, hot and excitable. But the Enigmatic’s powerful EQ and gain controls, multiple virtual cab and mic pairings, rock, jazz, and custom voices, plus additional deep, bright, and presence controls enable you to travel many leagues from that fundamental tone. The customization work you can do in the app enables significant changes in the Enigmatic’s tone profile and responsiveness, too. All these observations are made tracking the Enigmatic straight to a DAW—making the breadth of its personality even more impressive. But the Enigmatic sounds every bit as lively at the front end of an amp, and black-panel Fenders are a primo pairing for its saturation and sparkly attributes. The Enigmatic is nearly $400, which is an investment. But considering the ground I covered in just a few days with it, and the quality and variety of sounds I could conjure with the unit just sitting on my desk, the performance-to-price ratio struck me as very favorable indeed.
Lollar Pickups introduces the Deluxe Foil humbucker, a medium-output pickup with a bright, punchy tone and wide frequency range. Featuring a unique retro design and 4-conductor lead wires for versatile wiring options, the Deluxe Foil is a drop-in replacement for Wide Range Humbuckers.
Based on Lollar’s popular single-coil Gold Foil design, the new Deluxe Foil has the same footprint as Lollar’s Regal humbucker - as well as the Fender Wide Range Humbucker – and it’s a drop-in replacement for any guitar routed for Wide Range Humbuckers such as the Telecaster Deluxe/Custom, ’72-style Tele Thinline and Starcaster.
Lollar’s Deluxe Foil is a medium-output humbucker that delivers a bright and punchy tone, with a glassy top end, plenty of shimmer, rich harmonic content, and expressive dynamic touch-sensitivity. Its larger dual-coil design allows the Deluxe Foil to capture a wider frequency range than many other pickup types, giving the pickup a full yet well-balanced voice with plenty of clarity and articulation.
The pickup comes with 4-conductor lead wires, so you can utilize split-coil wiring in addition to humbucker configuration. Its split-coil sound is a true representation of Lollar’s single-coil Gold Foil, giving players a huge variety of inspiring and musical sounds.
The Deluxe Foil’s great tone is mirrored by its evocative retro look: the cover design is based around mirror images of the “L” in the Lollar logo. Since the gold foil pickup design doesn’t require visible polepieces, Lollartook advantage of the opportunity to create a humbucker that looks as memorable as it sounds.
Deluxe Foil humbucker features include:
- 4-conductor lead wire for maximum flexibility in wiring/switching
- Medium output suited to a vast range of music styles
- Average DC resistance: Bridge 11.9k, Neck 10.5k
- Recommended Potentiometers: 500k
- Recommended Capacitor: 0.022ÎĽF
The Lollar Deluxe Foil is available for bridge and neck positions, in nickel, chrome, or gold cover finishes. Pricing is $225 per pickup ($235 for gold cover option).

The legendary string-glider shows Chris Shiflett how he orchestrated one of his most powerful leads.
Break out your glass, steel, or beer bottle: This time on Shred With Shifty, we’re sliding into glory with southern-rock great Derek Trucks, leader of the Derek Trucks Band, co-leader (along with wife Susan Tedeschi) of the Tedeschi Trucks Band, and, from 1999 to 2014, member of the Allman Brothers Band.
Reared in Jacksonville, Florida, Trucks was born into rock ’n’ roll: His uncle, Butch Trucks, was a founding member of the Allman Brothers Band, and from the time he was nine years old, Derek was playing and touring with blues and rock royalty, from Buddy Guy to Bob Dylan. Early on, he established himself as a prodigy on slide guitar, and in this interview from backstage in Kalamazoo, Michigan, Trucks explains why he’s always stuck with his trusty Gibson SGs, and how he sets them up for both slide and regular playing. (He also details his custom string gauges.)
Trucks analyzes and demonstrates his subtle but scorching solo on “Midnight in Harlem,” off of Tedeschi Trucks Band’s acclaimed 2011 record, Revelator. In it, he highlights the influence of Indian classical music, and particularly sarod player Ali Akbar Khan, on his own playing. The lead is “melodic but with Indian-classical inflections,” flourishes that Trucks says are integral to his playing: It’s a jazz and jam-band mentality of “dangling your feet over the edge of the cliff,” says Trucks, and going outside whatever mode you’re playing in.
Throughout the episode, Trucks details his live and studio set ups (“As direct as I can get it”), shares advice for learning slide and why he never uses a pick, and ponders what the future holds for collaborations with Warren Haynes.
