Every shape in here is one, two or three fingers. None of them are hard. All of them sound like you know something the listener doesn't — because harmonic sophistication comes from which notes you leave out, not how many you cram in.
Why leaving notes out sounds richer
A full six-string chord tells the listener exactly what it is. A three-note voicing with no root leaves the identity ambiguous, and the ear fills the gap with the most interesting option available. That ambiguity is the sophistication. It's why piano players voice with their right hand only and let the bass imply the root.
The bottom four strings are all tuned a perfect fourth apart. So a flat one-finger barre across any three of E, A and D — or A, D and G — gives you a stack of fourths. Quartal voicings have no third, which means no major and no minor, which means they fit everywhere and commit to nothing. One finger. This is the single highest return in the pack.
B is tuned a major third from G, not a fourth. Any shape that crosses onto the B string needs one extra fret to keep the interval. That's the only complication in the whole document, and you can avoid it entirely by staying on the bottom four strings.
Six devices, hardest last
Flat-barre three strings. That's it. That's the exercise. It sounds like McCoy Tyner and it takes one finger.

No third anywhere. The voicing refuses to say whether it's major or minor, so the ear reads it as deliberately modal rather than incomplete. The same barre at fret 7 over an E bass reads as E11; at fret 5 it reads as a Cmaj9 sitting on E. One shape, two completely different harmonic implications, zero extra fingers.
You already know every major and minor triad. Put one over a bass note it doesn't belong to and you've built a chord with a name most guitarists can't spell.
| Bass note | Play this triad | What it becomes | Sounds like |
|---|---|---|---|
| C | B♭ major | C9sus4 | Steely Dan intro |
| C | D major | C6/9♯11 | Lydian, film score |
| C | E minor | Cmaj7 | Warm, resolved |
| C | E♭ major | Cm7 | Instant minor depth |
| C | G minor | C9 (no 3rd) | Floating dominant |
| A | C major | Am7 | The easiest of the lot |
Every one of these is a seventh or extended chord, and you're playing shapes you learned in your first month. The bass note does all the harmonic work. Learn the pattern rather than the list: a triad a whole step below the bass gives 9sus4, a whole step above gives Lydian, a major third above gives maj7, a minor third above gives m7.
Let the top two strings ring open and slide a two-note shape underneath. The open strings become whatever they need to be — a 9th here, an 11th there — and you never touch them.

Fretted notes moving against fixed open strings produce intervals you would never choose deliberately — seconds, ninths, elevenths — and because the open strings stay constant, the ear hears it as one evolving chord rather than a sequence of separate ones. It's most of Andy Summers' career and a fair chunk of Eric Johnson's.
Hold the top of the chord absolutely still. Walk the bass note down chromatically. You've written a string arrangement.

Contrary motion — one voice moving while others hold — is the oldest trick in Western harmony and it's the thing guitarists almost never do, because guitar shapes move as blocks. Breaking one voice out of the block instantly reads as arrangement rather than strumming.
A diminished seventh shape repeats every three frets and stays the same chord. Learn one grip, get twelve positions and four names for free.
Symmetrical chords have no home key, so they belong nowhere and fit anywhere. Sliding one in minor thirds sounds like deliberate harmonic motion when it's actually the same four notes in a different order. This is the single laziest way to sound like you can read.
Everything above, applied to the thing you actually asked for. Palm-muted low strings, three-note stabs, no root anywhere.

Riff B is the pack in miniature — a fixed two-note top with a single voice walking underneath, over a droning open string. Three ideas at once, one moving finger. Riff C works because of the silence: quartal voicings are ambiguous enough that the ear keeps working on them after they stop, so the gaps do as much as the notes.
Two things, then stop reading
Do 01 and 02 first and do them for a week before touching anything else. They're the two that generalise — the one-finger stack and the triad-over-wrong-bass system will change how you voice everything you already play. The other four are applications of them.
Rootless voicings fall apart under heavy gain, because distortion generates intermodulation between close intervals and turns ambiguity into mud. Play all of this on the clean side or with a single light drive. The Butter Machine at low gain works; the whole stack does not.
