How to Play Guitar Fills Between Chords: Simple Techniques That Sound Great

A fill is what separates competent rhythm playing from genuinely musical playing. A fill is the small flourish - usually just a few notes - that happens between chords or at the end of a phrase. It bridges the gap between chord changes and adds texture, interest, and professionalism to your arrangements.

The beautiful part about fills is that you don’t need to be a lead guitarist to play them. Simple, tasteful fills often sound better than flashy ones. A well-placed hammer-on, a quick pentatonic run, or a walking bassline between chords can transform an ordinary progression into something that sounds polished and intentional.

What Makes a Good Fill?

Before we dive into specific techniques, let’s define what makes a fill work:

It connects two moments: A fill happens during a chord change, usually in the space between chords or during a transitional moment.

It’s short: Most fills are just 2-4 notes. If it’s longer, it’s probably a lead guitar line, not a fill.

It fits the pocket: A good fill sits in the space without disrupting the feel. It should sound like it belongs there.

It creates forward motion: Fills move the music forward. They generate momentum toward the next chord or section.

The most important thing: a fill should enhance the song, not distract from it. A flashy fill that draws attention away from the vocal or the main melody is a bad fill, no matter how technically impressive.

Hammer-On and Pull-Off Fills

These are the simplest fills to learn, and they sound immediately professional. A hammer-on is when you pick a note and then “hammer” another finger down on a higher fret to create a second note without picking. A pull-off is the reverse - you pick a note and pull your finger off to create a lower note.

Basic Hammer-On Fill

Pick an open E note on the low E string and hammer onto the second fret (F). That’s a hammer-on fill. One note is picked, the second is created by the hammer motion.

Example fill between Am and F:

Pick on E string: E (open) | Hammer to F | Let ring into Am chord
e|---0---|
B|---0---|
G|---2---|
D|---2---|
A|---1---|
E|---0-1-|

That’s it. One picked note, one hammered note. It sounds fluid, intentional, and professional. This works because the hammer-on creates a smooth legato sound that’s impossible to achieve with two separate picks.

Basic Pull-Off Fill

Pick a note on a higher fret and pull off to a lower note. For example, pick the F note (second fret E string) and pull your finger off to the open E.

Pick F and pull to E open
e|---0---|
B|---0---|
G|---2---|
D|---2---|
A|---1---|
E|---1-0-|

Pull-offs feel slightly different than hammer-ons - they have a lighter, slightly shorter tail. Use them when you want to create a descending motion during a chord change.

Combining Hammer-Ons and Pull-Offs

Here’s a two-note fill combining both techniques:

Between D and G, try this on the B string:

Pick D (open B string)
Hammer to E (second fret)
Pull off back to D
Let it ring into the G chord

This three-note fill uses minimal technique but creates sophisticated movement. The hammer-on climbs, the pull-off descends - great for creating tension before a new chord lands.

Bass Note Walks

Walking basslines are one of the most musical and useful fills available. Instead of jumping between chord roots, you move through connecting notes that lead smoothly from one chord to the next.

Simple Walking Bass Between Chords

From C to F, instead of playing C then jumping to F, walk the bass:

C (root) - C# or B (connecting note) - D - Eb/D# - E - F

Or more simply: C - D - E - F

Pick each note slowly on the low E string:

C walk to F
E|---0-2-4-5-|

The bass is now moving step-wise instead of jumping. This creates smooth voice leading and sounds much more intentional than a static root change.

Walking Bass in Context

Play a chord progression with walking bass fills:

Am to G: Walk from A down to G: A - G# - G G to F: Walk from G down to F: G - F# - F F to C: Walk from F up to C: F - G - A - B - C

Now play this progression normally, but add the walking bass on the low E string during the chord changes:

Am (1 beat) | A-G#-G (walk) | G (land on 1)
G (1 beat) | G-F#-F (walk) | F (land on 1)
F (1 beat) | F-G-A-B-C (walk) | C (land on 1)

The walking bass creates forward momentum. It sounds professional because it’s harmonic (every note is part of a scale or moving toward the next chord) and smooth (every note is step-wise, not jumping).

Walking Bass in 4/4 Time

In a standard measure of 4/4, you can fit a four-note walk:

From Dm to G:

Beat 1: D (Dm chord)
Beat 2: Dm chord continues
Beat 3: Dm chord continues (this is where the walk often starts)
Beats 3.5-4: D - E - F# - G (four walking notes leading into G)

The walk creates a smooth landing on the G chord at the top of the next measure.

Pentatonic Fills

If you know a pentatonic scale, you can instantly create fills. The pentatonic scale is five notes that always sound good together. For example, A minor pentatonic: A - C - D - E - G.

Simple Pentatonic Fill

Play a pentatonic scale quickly during a chord change. From Am to C, quickly run:

A-C-D-E-G pentatonic run
e|---0---|
B|---0---|
G|---2---|
D|---2---|
A|---0-3-5-7-|
E|---0---|

Play this as a quick ascending run that lands on the C chord. It’s exactly four notes - fast enough to feel like a fill, not slow enough to be a lead line.

Single-String Pentatonic Fills

Stay on one string for clarity. Play your pentatonic scale on a single string and extract just 2-4 notes for a fill.

Low E string, A pentatonic fill between two chords:

Quick run A-C-D-E on low E
E|---0-3-5-7-|

The beauty of pentatonic fills is that any combination of those notes sounds good. You can’t really play a “wrong” fill with pentatonic patterns.

Chord Embellishment Fills

Some fills don’t come from scales - they come from notes within the chord itself. These are chord embellishment fills, and they’re subtle but effective.

The Arpeggio Fill

An arpeggio is playing the notes of a chord separately rather than strumming them together. Play a quick arpeggio as a fill:

C arpeggio fill: C-E-G-C
e|---0---|
B|---1---|
G|---0---|
D|---2---|
A|---3---|
E|---x-1-0-3-5-|

Pick the chord notes quickly - this works especially well on the low end of the fretboard, where it creates a bass-driven fill.

The Sus Fill

Use suspended notes (sus2 or sus4) as fills. For an Am chord, play:

Am (pick chord)
Asus4 (add the D, the 4th)
Am (resolve back)

This creates movement within a single chord. The suspended note creates slight tension that resolves beautifully back to the original chord.

Genre-Specific Fill Ideas

Blues Fills

Blues fills often use the minor pentatonic scale or quick blue notes. A classic blues fill might be:

Playing the minor third (Db in the key of A) slightly bent, then sliding down to the root. These are quick, expressive, and define blues guitar.

Acoustic/Folk Fills

Acoustic fills often emphasize bass note movement and open strings. Walking bass is extremely common. Also common: quick runs through open string positions that create a harp-like cascading effect.

Jazz Fills

Jazz fills are often chromatic - moving through notes a half-step apart. They’re subtle and sophisticated, enhancing harmony rather than drawing attention.

Indie/Alternative Fills

These often use pentatonic scales with a loose, almost careless feel. The goal is understated musicality - fills that enhance without being flashy.

When to Play Fills

Fills work best:

During chord changes: The space between chords is fill territory.
At the end of phrases: When a vocal line ends or a section closes, a fill can bridge into the next section.
To create contrast: If you’re playing straight rhythm, a fill adds texture and interest.
To answer musical questions: If a melody asks something, answer with a fill.

Fills should NOT:

Distract from the main melody or vocal
Happen constantly - they lose their punch with overuse
Be technically impossible to execute cleanly - a botched fill is worse than no fill
Last longer than 2-4 beats (unless it’s intentionally building to something)

Building Your Fill Vocabulary

The best guitarists have a large vocabulary of fills they can deploy instantly. Here’s how to build yours:

Week 1-2: Master simple hammer-on and pull-off fills between two common chords (like Am to C).

Week 3-4: Learn walking basslines in two keys.

Week 5-6: Add pentatonic fills to your toolkit.

Week 7+: Combine techniques, experiment with different styles, and develop personal preference.

Try This in Guitar Wiz

Guitar Wiz makes learning fills practical and measurable:

Song Maker Practice: Create simple two-chord progressions in the Song Maker and practice fills between the chords. Start at a slow tempo and focus on clean execution rather than speed.

Metronome Support: Use the metronome to keep time while practicing fills. Set it to give you clear beat references so you know exactly where your fill needs to land.

Interactive Chord Diagrams: Use the app’s chord diagrams to quickly move between chords while practicing fill transitions. Less time thinking about fingerings means more time focused on the fills themselves.

Explore Chord Library: Search for chord variations (like Csus4 or Asus2) to understand how suspended chords work for embellishment fills.

Record and Playback: Some apps let you record your playing. Record yourself playing chords with fills, then listen back to evaluate timing and musicality. This ear training is crucial for developing good fill instincts.

Conclusion

Fills are where good playing becomes musical playing. They’re the moments where you get to be creative and expressive within a framework. A well-timed, well-executed fill tells the listener “this guitarist knows what they’re doing.”

Start simple. Master the hammer-on/pull-off. Add walking bass. Explore pentatonic runs. Within weeks, you’ll have the tools to add sophistication and musicality to any song. The key is restraint - less is usually more with fills. One perfect fill is worth ten mediocre ones.

Practice these techniques slowly until they’re automatic. Then speed them up until they feel natural at normal playing tempo. Once you’ve got a fill toolkit, you can focus on the music itself rather than the mechanics.

FAQ

How long should a fill be?

Most fills are 2-4 notes. Anything longer is probably a lead guitar line rather than a fill. Remember, a fill’s job is to bridge between moments, not to be the main event.

Can I use the same fill multiple times in a song?

Absolutely. Repetition is musical. If a fill works once, it’ll work again. Many songs use the same fill between every chorus change. Just make sure the fill genuinely fits the music.

What if my fill sounds awkward between two chords?

Trust that instinct. Not every fill works between every chord pair. Try a different fill or a different technique. Some chord combinations naturally call for certain types of fills.

Do fill techniques apply to lead guitar too?

Yes. Everything here applies to lead. The difference is just duration and context. A fill is usually 2-4 beats in the rhythm framework. A lead line is longer and takes more space.

How do I know where the fill should land?

Usually the fill happens during the last beat or two of a chord before moving to the next chord. The fill should land and resolve into the new chord cleanly, making the transition smooth rather than abrupt.
