How to Use Intervallic Playing for Creative Guitar Solos

Most guitarists learn to solo by running up and down scales. This is a natural starting point, but it creates a predictable pattern: your solos move step by step, note by note, sounding more like exercises than music. The notes are technically correct, but the lines lack the melodic character that makes a solo memorable.

Intervallic playing is the antidote. Instead of moving from one scale degree to the next (a second), you skip notes and jump to wider intervals - thirds, fourths, fifths, sixths, and beyond. This creates unexpected leaps in your melodies that sound more composed, more intentional, and more musical.

What Are Intervals on Guitar?

An interval is simply the distance between two notes. When you play C to D, that’s a second (two note names apart). C to E is a third. C to F is a fourth. C to G is a fifth. C to A is a sixth.

On guitar, intervals have consistent physical shapes. A minor third is always three frets on the same string. A perfect fourth is always the same two-string shape (except between strings 3 and 2, where it shifts by one fret due to guitar tuning). Once you learn these shapes, you can play any interval anywhere on the neck without thinking about note names.

This is a huge advantage guitarists have over other instrumentalists. The visual and physical patterns of intervals are constant and moveable.

Starting with Thirds

Thirds are the most musical-sounding interval for soloing because they’re the building blocks of chords and harmony. When you play in thirds through a scale, the result sounds like a melody rather than an exercise.

Take the A minor pentatonic scale in the first position. Instead of playing A-C-D-E-G in sequence, play every other note: A-D, C-E, D-G, E-A, G-C. You’re skipping a note each time, creating a third between each pair.

On the fretboard, this translates to playing the 5th fret of the 6th string (A), then jumping to the 7th fret of the 5th string (D). Then the 3rd fret of the 5th string (C) followed by the 5th fret of the 4th string (E). The pattern continues up through the scale position.

Practice this ascending and descending. The sound is immediately more interesting than running the scale straight up and down.

Adding Fourths for Angular Lines

Fourths create a more angular, modern sound compared to the smooth quality of thirds. Jazz players like John Scofield and rock players like Alex Lifeson use fourths extensively to create lines that zig-zag across the fretboard.

In the minor pentatonic scale, fourths show up naturally. From A to D is a fourth. From C to E is a major third (close to a fourth). From D to G is a fourth. The pentatonic scale is actually built largely from fourths, which is why quartal ideas work so well over pentatonic-based music.

On the fretboard, a perfect fourth on adjacent strings sits at the same fret (except between strings 3 and 2). So playing the 5th fret of the 6th string and the 5th fret of the 5th string gives you a fourth. Move this shape up the neck and across string pairs to create angular interval patterns.

Sixths: The Secret Weapon

Sixth intervals have a sweet, vocal quality that’s been used in everything from country to soul to classic rock. Think of the twin-guitar harmonies in bands like The Allman Brothers or the intro licks in dozens of Motown recordings.

On guitar, sixths typically sit on non-adjacent strings - like the 4th and 2nd strings or the 3rd and 1st strings. In the key of C major, a sixth pattern on strings 4 and 2 moves through: C and A (frets 10 and 10), D and B (frets 12 and 12), E and C (frets 14 and 13), and so on up the neck.

These double stops sound full and melodic played together. Try picking both strings simultaneously or rolling from the lower string to the higher one with a slight delay. Add slides between positions for a smooth, vocal feel.

Building Intervallic Sequences

Once you’re comfortable with individual intervals, chain them into sequences. A sequence is a repeating pattern applied to each note of a scale.

For example, a “thirds sequence ascending” in A minor pentatonic goes: A up to D, C up to E, D up to G, E up to A, G up to C. Each pair moves up a third, and the starting note of each pair moves up through the scale.

A “fourths sequence descending” reverses the direction: start high and work down, jumping a fourth below each scale tone before moving to the next.

You can also mix intervals. Play a third up, step down a second, play another third up, step down again. This creates a rolling, wave-like melodic pattern that has real musical momentum.

Applying Intervals Over Chord Changes

The real power of intervallic playing shows up when you solo over chord progressions. Instead of running the same pentatonic box over every chord, target the chord tones of each chord using intervallic approaches.

Over an A minor chord, emphasize the notes A, C, and E. Over a D minor chord, shift your emphasis to D, F, and A. The interval jumps between these target notes create lines that follow the harmony rather than sitting on top of it.

A practical approach: when the chord changes, leap a third or fourth to land on a chord tone of the new chord. This interval jump signals the chord change to the listener’s ear and makes your solo sound harmonically aware.

Breaking the Box Pattern

One reason scalar playing gets boring is that guitarists get locked into one position on the neck. Intervallic playing naturally breaks you out of this because wider intervals often require position shifts.

A sixth interval on the same string covers 8 or 9 frets. Playing sixths across strings uses smaller stretches but still moves you across the fretboard laterally. These wider movements create a visual and sonic impression of using the whole neck.

Try this exercise: pick any note on the 6th string. Play a fourth above it, a sixth above that, a third below, and a fifth above. You’ll find yourself covering significant fretboard territory in just four notes. This kind of movement sounds confident and intentional.

Intervals and Rhythm Together

Intervallic playing gets even more interesting when combined with rhythmic variation. Instead of playing intervals in steady eighth notes, try accenting the larger jumps and letting them ring longer. Play smaller intervals as quick connecting phrases and wider intervals as dramatic leaps that hang in the air.

Syncopation also helps. Place your interval jumps on off-beats for a more sophisticated rhythmic feel. A sixth interval landing on the “and” of beat 2 has a completely different character than the same interval on beat 1.

Practice Strategies

Start with one interval at a time. Spend a week on thirds: play them ascending, descending, and in sequences through every scale you know. Then move to fourths, then sixths.

Record yourself playing scalar solos, then play the same progression using intervallic approaches. Listen back and compare. You’ll hear the difference immediately - the intervallic version will sound more composed and deliberate.

Use backing tracks. Intervallic playing only makes sense in a musical context. Soloing over a drone or a simple chord progression lets you hear how intervals interact with the harmony in real time.

Try This in Guitar Wiz

Guitar Wiz’s chord library is an excellent tool for visualizing intervals across the fretboard. When you look at chord voicings, you’re actually looking at intervals stacked together. Study how the notes in a chord are spaced across the strings to understand interval shapes visually.

Use the Song Maker to create simple two or three-chord progressions as practice backing tracks. Build a loop in A minor (Am - Dm - Em - Am) and practice applying third and sixth intervals over the changes.

The interactive chord diagrams show you exactly where chord tones sit on the neck. When you’re soloing over a particular chord, reference the Guitar Wiz diagram to find target notes for your intervallic jumps. Over time, these positions become second nature.

Practice your intervallic sequences with Guitar Wiz’s metronome set to a slow tempo. Accuracy matters more than speed with intervals. Once you can nail each jump cleanly at 70 BPM, gradually increase the tempo.

Making It Musical

The goal of intervallic playing isn’t to avoid stepwise motion entirely. The best solos combine scale runs, interval jumps, repeated notes, and space. Think of intervals as one more tool in your expressive toolkit - a way to add surprise, range, and melodic interest to lines that might otherwise plod along predictably.

Start by inserting one or two interval jumps into your existing solo approach. A single well-placed sixth leap in the middle of a pentatonic run can transform a forgettable lick into a memorable phrase.
