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.

Tom Bedell in the Relic Music acoustic room, holding a custom Seed to Song Parlor with a stunning ocean sinker redwood top and milagro Brazilian rosewood back and sides.
A born storyteller, Bedell doesn’t keep his passion to himself. On Friday, May 12, at New Jersey boutique guitar outpost Relic Music, Bedell shared some of the stories he’s collected during his life and travels as part of a three-city clinic trip. At Relic—and stops at Crossroads Guitar and Art in Gilbertsville, Pennsylvania, and Chuck Levin’s Washington Music Center in Wheaton, Maryland—he discussed his guitars and what makes them so special, why sustainability is such an important cause, and how he’s putting it into practice.
Before his talk, we sat in Relic’s cozy, plush acoustic room, surrounded by a host of high-end instruments. We took a look at a few of the store’s house-spec’d Bedell parlors while we chatted.
“The story of this guitar is the story of the world,” Bedell explained to me, holding a Seed to Song Parlor. He painted a picture of a milagro tree growing on a hillside in northeastern Brazil some 500 years ago, deprived of water and growing in stressful conditions during its early life. That tree was eventually harvested, and in the 1950s, it was shipped to Spain by a company that specialized in church ornaments. They recognized this unique specimen and set it aside until it was imported to the U.S. and reached Oregon. Now, it makes the back and sides of this unique guitar.

As for the ocean sinker redwood top, “I’m gonna make up the story,” Bedell said, as he approximated the life cycle of the tree, which floated in the ocean, soaking up minerals for years and years, and washed ashore on northern Oregon’s Manzanita Beach. The two woods were paired and built into a small run of exquisitely outfitted guitars using the Bedell/Breedlove Sound Optimization process—in which the building team fine-tunes each instrument’s voice by hand-shaping individual braces to target resonant frequencies using acoustic analysis—and Bedell and his team fell in love.
Playing it while we spoke, I was smitten by this guitar’s warm, responsive tone and even articulation and attack across the fretboard; it strikes a perfect tonal balance between a tight low-end and bright top, with a wide dynamic range that made it sympathetic to anything I offered. And as I swapped guitars, whether picking up a Fireside Parlor with a buckskin redwood top and cocobolo back and sides or one with an Adirondack spruce top and Brazilian rosewood back and sides, the character and the elements of each instrument changed, but that perfect balance remained. Each of these acoustics—and of any Bedell I’ve had the pleasure to play—delivers their own experiential thumbprint.

Ultimately, that’s what brought Bedell out to the East Coast on this short tour. “We have a totally different philosophy about how we approach guitar-building,” Bedell effused. “There are a lot of individuals who build maybe 12 guitars a year, who do some of the things that we do, but there’s nobody on a production level.” And he wants to spread that gospel.
“We want to reach people who really want something special,” he continued, pointing out that for the Bedell line, the company specifically wants to work with shops like Relic and the other stores he’s visited, “who have a clientele that says I want the best guitar I can possibly have, and they carry enough variety that we can give them that.”

The Gibson EH-185, introduced in 1939, was one of the company’s first electric guitars.
It’s hard to overstate the importance of electric guitar in shaping American popular music over the last half-century. Its introduction was a revolution, changing the course of modern musical styles. Today, when we think of the guitars that started the revolution, we think of the Stratocaster and the Les Paul, guitars held against the body and fretted with the fingertips. But the real spark of this musical mutiny was the lap-steel guitar.
In the early 20th century, guitar music was moving out of the parlors of homes and into public spaces where folks could gather together and dance. Guitarists needed to project their sound far beyond where their wimpy little acoustic instruments could reach. Instrument manufacturers began experimenting with larger body sizes, metal construction, and resonators to increase volume.
Around this time, George Beauchamp began experimenting with electric guitar amplification. He settled on a design using two U-shaped magnets and a single coil of wire. Beauchamp was in business with Adolph Rickenbacker, and they decided to stick this new invention into a lap steel.
If we put on our 1930s glasses, this decision makes perfect sense. The most popular music at the time was a blend of Hawaiian and jazz styles made famous by virtuosos like Solomon “Sol” Hoʻopiʻi. Photos of Hoʻopiʻi with a metal-body resonator abound—one can imagine his relief at being handed an instrument that projected sound toward the audience via an amplifier, rather than back at his own head via resonator cones. Beauchamp and Rickenbacker were simply following the market.
As it turned out, the popularity of Hawaiian music gave way to swing, and electric lap steels didn’t exactly take the world by storm. But Beauchamp and Rickenbacker had proven the viability of this new technology, and other manufacturers followed suit. In 1937, Gibson created a pickup with magnets under the strings, rather than above like Beauchamp’s.
“When I plugged in the EH-185 I expected to hear something reminiscent of Charlie Christian’s smooth, clean tone. But what I got was meatier—closer to what I associate with P-90s: warm and midrange-y.”
The first page of Gibson’s “Electrical Instruments” section in the 1939 catalog features a glowing, full-page write-up of their top-of-the-line lap steel: the EH-185. “Everything about this new electric Hawaiian Guitar smacks of good showmanship,” effuses the copy. “It has smoothness, great sustaining power, and an easy flow of tone that builds up strongly and does not die out.”
Picking up the 1940 EH-185 at Fanny’s House of Music is about as close as one can get to traveling back in time to try a new one. It is just so clean, with barely any dings or even finish checking. Overall, this is a 9/10 piece, and it’s a joy to behold. Speaking of picking it up, the first thing you notice when you lift the EH-185 out of the case is its weight. This is a much heavier instrument than other similar-sized lap steels, owing to a length of thick metal between the body and the fretboard. The catalog calls it “Hyblum metal,” which may be a flowery trade name for an early aluminum alloy.

There are numerous other fancy appointments on the EH-185 that Gibson didn’t offer on their lesser models. It’s made of highly figured maple, with diamond-shaped decorations on the back of the body and neck. The double binding is nearly a centimeter thick and gives the instrument a luxurious, expensive look.
Behind all these high-end attributes is a great-sounding guitar, thanks to that old pickup. It’s got three blades protruding through the bobbin for the unwound strings and one longer blade for the wound strings. When I plugged in the EH-185 I expected to hear something reminiscent of Charlie Christian’s smooth, clean tone. But what I got was meatier—closer to what I associate with P-90s: warm and midrange-y. It was just crying out for a little crunch and a bluesy touch. It’s kind of cool how such a pristine, high-end vintage instrument can be so well-suited for a sound that’s rough around the edges.
As far as electric guitars go, it doesn’t get much more vintage than this 1940 Gibson EH-185 Lap Steel. It reminds us of where the story of the electric guitar truly began. This EH-185 isn’t just a relic—it’s a testament to when the future of music was unfolding in real time. Plug it in, and you become part of the revolution.
