Funk Rhythm Guitar: How to Use Intervals of Thirds

Intervals of thirds are one of the most powerful tools in funk rhythm guitar. They sit in a sweet spot: fuller than a single note, but lighter and more mobile than a full chord voicing. That combination gives you a horn-like, melodic quality that chords alone simply cannot deliver. If you’ve been exploring the 6th-9th chord combo as a movable rhythm foundation, thirds are the natural next layer to add. The challenge is learning them without drowning in patterns. This article walks you through Rick Stickney’s approach: anchor small groups to shapes you already know, then build from there. That method keeps the material manageable and puts the sounds in your hands fast.

Why Intervals of Thirds Belong in Your Funk Toolkit

A single note is thin. A full chord voicing is heavy. Intervals of thirds live between those two worlds. They add color and harmonic weight, but they leave rhythmic space open. That openness matters in funk, where the groove lives in the gaps just as much as in the notes.

Thirds also carry a melodic quality. They imply movement. A horn section playing a stacked third figure over a dominant groove does exactly this. On guitar, double stops built from the harmonized scale produce the same feeling. They pull the listener forward without cluttering the pocket.

In a strong funk rhythm part, texture contrast is everything. You alternate between muted single-note lines, full chord hits, and these lighter third intervals. Each texture sets up the others. Intervals of thirds are the middle voice that ties the whole thing together.

How to See Thirds Along the Neck, Not Just in Box Shapes

Here is where most players run into trouble. The harmonized scale gives you thirds on every string pair. However, most guitarists see scales vertically, in boxes. Thirds don’t live comfortably in box shapes. They run horizontally, string pair by string pair, across the neck.

So, first, learn the pattern on one string pair. For example, take the G and B strings. Find two adjacent scale tones. Play them together. That’s your first third. Next, shift up to the next pair of scale degrees on the same two strings. Then keep going up the neck. You’re now reading the harmonized scale as a horizontal line of double stops.

After that, move to the D and G strings and repeat the same process. Each string pair has its own fingering, because of the guitar’s tuning. Because the tuning shifts between the G and B strings, the shape changes there specifically. Learn each pair on its own terms. Don’t assume the same fingering transfers automatically.

Rick’s Method: Two or Three at a Time, Anchored to a Shape

Trying to memorize every third across every string pair at once is a reliable way to quit before it clicks. Rick Stickney’s approach avoids that trap. Take two or three of these double stops at a time. Anchor each small group to a voicing you already know.

For example, if you know a dominant 9 chord in a particular position, find the thirds that sit inside that shape. They’re already there. Suddenly, you’re not learning something new. Instead, you’re discovering something familiar in different clothing. That recognition is what makes the pattern stick.

Because these shapes are movable, this approach pays off fast. Own a group of thirds in one position, and you already own them everywhere else on the neck. Nothing changes but the fret location. Therefore, one small investment of focused practice scales across the entire fingerboard. That’s a very efficient trade.

Stacking Thirds Vertically Inside Chord Voicings

In addition to running thirds horizontally along a string pair, learn how they stack vertically inside your chord shapes. Pull up any dominant voicing you already know. Look at adjacent string pairs inside that shape. You’ll find thirds built right into the chord.

This is what lets you move fluidly between a full voicing and a two-note double stop in the middle of a groove. You’re not shifting your hand position. Instead, you’re simply choosing which notes to sound. That interchangeability is the real goal. When breaking out of a single chord shape is the aim, knowing where your thirds live inside existing voicings is a direct solution.

Creative Move: Chromatic Passing Double Stops

Once you can locate intervals of thirds along the neck, try slipping a chromatic passing double stop between two target ones. Move from one diatonic third to another, but add a half-step double stop in between. That passing move creates a smooth, forward-leaning, soulful motion.

This technique is a staple of funk rhythm vocabulary. It sounds like a horn line. It sounds intentional. In fact, it’s one of the moves that separates a groove from a pattern. The chromatic approach note creates tension. The arrival on the target third releases it. That push and pull is the engine of funk phrasing.

Creative Move: Palm Muting for a Punchy, Percussive Texture

Palm muting intervals of thirds is one of the most recognizable sounds in funk rhythm guitar. Rest the side of your picking hand lightly on the strings near the bridge. Then strike those double stops. The result is a tight, compressed, percussive punch. It cuts through a full band without adding harmonic clutter.

This muted texture is especially effective when you alternate it with open, ringing double stops in the same phrase. The contrast between the two creates rhythmic interest. Meanwhile, your fretting hand barely moves. The right hand is doing the heavy lifting.

Putting Thirds to Work in a Real Groove

Intervals of thirds work best when woven alongside other textures. Start a phrase with muted single notes. Hit a full chord on a strong beat. Then drop in a third double stop as a melodic fill. Finally, add a chromatic passing move on the way to the next downbeat. That sequence creates shape. Each element highlights the others.

This kind of textural awareness is central to strong funk lead phrasing as well. The rhythm and lead worlds in funk overlap more than most players realize. Thirds blur that line in a productive way.
