“I use DADGAD for about 50 percent of my music,” says fingerstyle wizard Laurence Juber as he coaxes his Martin into the exotic altered tuning. “It opens up dimensions on the
The pioneering Davey Graham is hailed as the father of DADGAD. A key figure in the early-’60s British folk music scene, the fingerpicker was known for injecting jazz, blues, and North African sounds into traditional Celtic music. Bert Jansch, John Renbourn, Martin Carthy, Jimmy Page, Pierre Bensusan, Michael Hedges, and Martin Simpson are among the many guitarists who seized on Graham’s innovative tuning scheme and incorporated it into their own work.

“First off,” says Juber, “compared to standard, DADGAD is a dropped tuning. Lower your sixth and first strings a whole-step to D, then lower your second string a whole-step to A, and you’re there [Ex. 1].You’ve only changed three strings. Assuming we’re in the key of D, the third and second strings are adjacent scale tones—G and A. This simple fact allows you to easily play scale fragments and melodies using combinations of fretting notes and open strings for a harp-like sound.
“For instance,” Juber continues, “try this simple passage [Ex. 2a]. If you keep holding the F# while you pick the open G and A strings, you’ll hear three adjacent scale tones ringing against each other. It’s dissonant, but beautiful. The hammers and pulls make the fretted notes sound more fluid and help you play fast phrases, like this one [Ex. 2b]. Remember, try to keep the open strings ringing as you work your way across the fretboard.”
“If you approach fingering creatively,” says Juber,” you’ll find other groups of adjacent scale tones. In this phrase [Ex. 3], I get two sets of three scale tones.”
As you play through this example, you’ll quickly discover the two sets Juber is referring to: D, C#, and B, played on strings one, two and three, and A, G, and F#, found on strings two, three, and four. To make the most of this “one-scale-tone-per-string” approach, arch your fretting fingers to allow each plucked string to vibrate freely, and hold the fretted notes as long as you can before releasing the string. If you’re careful, you can extract yet another set of ringing scale tones—B against A, on strings three and two. This pair acts as the hinge between the triple-note sets.
“In certain positions,” Juber reveals, “you can get four adjacent scale tones, like this [Ex. 4]. Here, I’ve refingered B and C#, so I can play in the fourth position.”
The four scale tones—E, F#, G, and A—lie on the fifth through second strings. Take advantage of the ringing open A string in beat two: During that eighth-note, release your previous grip and simultaneously clamp your 4th and 1st fingers on E and F# (strings five and four), where they’ll remain until the pull-off at the end of the measure. If you pick this phrase cleanly, your
“In DADGAD, says Juber, “octaves are immediately accessible.You’ve got three D strings and two A strings, which puts octaves on the same fret across three different string groups. A bluesy line like this is easy to finger in DADGAD [Ex. 5], once you see the octave relationship between strings four and one, five and two, and six and four.
“It’s easy to translate octaves into riffage. For example, a tune of mine called ‘Colbalt Blue’ [from The Collection] opens with this riff in D minor [Ex. 6]. It’s composed of octaves, and I fret and attack it using only one hand.” Thanks to the hammers and pulls, this swinging riff makes a superb fretting hand workout. To make the line groove, tap the octaves at the 2nd, 3rd, and 5th frets with enough force to make them louder than their companion pull-offs.
“Here’s another octave riff,” says Juber, playing Ex. 7. “It’s an ascending figure I play at the end of ‘Pass the Buck’ [on the album LJ], which is the second piece I wrote in DADGAD. It will help strengthen your pull-offs and also give you a chance to practice alternate picking on the first string.”
Another benefit to DADGAD, asserts Juber, is how it puts colorful harmony at your fingertips. “There’s an ambience that comes out of the tuning,” he explains, playing Ex. 8. “Because you’ve got adjacent scale tones, you can incorporate the 2, 4, or 6 into your chords without any finger gymnastics. In standard tuning, you can seek out these sounds, but in DADGAD, they come with the territory.”
To appreciate what Juber is saying, let’s don the theory goggles and take a closer look: In Gadd2, the open second string provides the 2. Notice how the root (G) and 2 (A) are located on adjacent strings, and form a major second interval. This major second appears again in Bbmaj13, but in this harmonic context, the open strings function as the 6 (G) and 7 (A). The final chord, Dadd4, offers a dissonant—yet very appealing—cluster: F#, G, and A. Composed of a minor second (F#-G) plus a major second (GA), the cluster accounts for three chord tones—the 3, 4, and 5—which are played on adjacent strings for maximum chime.
“So far, we’ve been exploring the keys of D and D minor,” says Juber, “but DADGAD shines in other keys too. For instance, in the key of A, you get a low, booming root on the IV chord, D. This is perfect for gospel-style, I-IV progressions. Of course in DADGAD, even standard I-IV changes offer extra harmonic color [Ex. 9].”
In this progression, the color comes from the 4, which, when added to a dominant-7th chord such as A7 or D7, yields A11 and D11. The minor second (C#-D) in A11 and major second (C-D) in D7 and D11 add a lovely twang to the four-bar phrase.
“This example also shows how DADGAD tends to emphasize the
“But you shouldn’t conclude that all chords played in DADGAD contain dissonant, close intervals,” cautions Juber. “For example, I play a solo
“The last Bb triad is worth mentioning. I could have played the D on the third string, but instead, I opted for the open first string because it rings so clearly. This also has a subtle effect on the temperament, shifting the 3 from the middle register of a wound string to an open, plain string. To my ears, this fingering sounds more like a string section. Details like this can make a huge textural difference in a solo-guitar arrangement.”
Legend has it Davey Graham developed DADGAD while traveling in Tangiers, as a way to make the
Technically, Ex. 12a uses a blend of D Dorian (D, E, F, G, A, B, C) and D Mixolydian (D, E, F#, G, A, B, C). The important nugget is this: With both an Fn and F# in the same measure, the phrase moves from minor to major within two beats. But its ambiguous nature sounds right, doesn’t it? Ex. 12b is straight-up D Mixolydian, sans E. That’s a classic jazzbo trick: When improvising, drop one tone from a mode or scale, and then stick to that abbreviated note pool for your solo. By creating a melodic gap, you add an element of surprise to your lines.
“Playing blues in DADGAD offers some cool melodic twists,” states Juber. “Strings five, four, and three are identical to standard tuning, so if you play a blues lick on those strings, it sounds completely normal [Ex. 13a]. But if you press on, playing across the top two strings, you get something like this [Ex. 13b]. Now that’s different—more modal or psychedelic. Familiar blues fingering patterns suddenly become a bit mysterious [Ex. 13c].”
“Now that we’ve heard some of the sounds DADGAD offers,” says Juber, “let’s conclude on a conceptual note: The tuning becomes less alien when you realize the relationship between the top two strings [A, D] and the bottom string [D] is the same as in standard tuning [B, E, and low E]. You have a fourth on top and two octaves between the sixth and first strings. The only difference is that in DADGAD, these three strings are a whole-step lower than in standard tuning. The fifth, fourth, and third strings remain unchanged, so all your favorite moves are still there. It’s as if you’ve shifted strings six, two, and one down two frets relative to the others.That’s all it is. From this perspective, DADGAD seems like an old friend.”
