How to Use Passing Chords on Guitar to Smooth Out Progressions

A passing chord is a brief chord that fills the space between two main chords in a progression. It’s not the destination - it’s the bridge. These chords add sophistication, smoothness, and forward motion to your progressions without cluttering them. They’re everywhere in jazz, pop, R&B, and any music that prizes smooth voice leading.

The beautiful thing about passing chords is that they’re not complicated or mysterious. Once you understand the concept, you can add them to almost any progression you write. This guide covers the main types of passing chords and shows you exactly how to use them.

What Exactly Is a Passing Chord?

A passing chord is a chord that appears on a weaker beat between two main chords. It’s harmonically “in between” its neighbors, creating smooth voice leading and forward momentum.

Think of a progression like C - F - G. That jump from C directly to F is fine, but inserting a passing chord creates more movement:

C - Dm - F - G

That Dm sits between C and F, smoothing the transition. It borrows from the key and creates a sense of motion rather than static jumps.

Passing chords typically:

• Appear on weaker beats (the “and” of beat 2, or beat 3)
• Last for half a measure or a beat
• Connect smoothly to both the chord before and after
• Don’t require the listener to “accept” them as important harmonically

They’re transitional - in and out quickly.

Types of Passing Chords

There are several types of passing chords, each with different characteristics and uses.

Chromatic Passing Chords

These move by half-step. They’re the most natural-sounding and commonly used.

If you’re moving from C major to D major, a chromatic passing chord would be C# (or Db). The bass note moves in half steps: C - C# - D.

Example progression: C - Db - D - G

Here’s how that looks:

C major:  x-3-2-0-1-0
Db major: x-4-3-1-2-1 (one fret up)
D major:  x-x-0-2-3-2
G major:  3-2-0-0-0-3

That Db is purely transitional. It appears for one beat, then moves to D. The bass line walks up chromatically: C - C# - D, which creates immediate forward motion.

Another example: G - G#dim - Am or G - Abmaj7 - Am. The half-step movement in the bass creates smoothness.

Diminished Passing Chords

Diminished chords are particularly useful as passing chords because they’re symmetrical - they fit between almost anything.

A diminished chord has an ambiguous quality. It doesn’t point toward a specific resolution, making it perfect for transitioning between unrelated harmonies.

Classic use: C - Bdim - Dm

The Bdim sits between C and Dm, smoothing that transition.

C major:  x-3-2-0-1-0
B dim:    x-2-3-4-3-4
Dm:       x-x-0-2-3-1

Another powerful one: G - F#dim - Am

This progression is all over jazz and sophisticated pop music. The diminished chord creates tension that resolves beautifully into Am.

Diminished passing chords work especially well because they’re brief and non-committal. They don’t anchor the listener to any particular key - they just smoothly transition between main harmonies.

Dominant Passing Chords

A dominant seventh chord (the V7) naturally pulls toward its resolution. You can use this property to create passing motion.

For example: C - E7 - Am

The E7 wants to resolve to Am (E is the fifth of Am), so it pulls you forward naturally. The listener’s ear expects that resolution, so the motion feels organic.

Another example: F - B7 - Em

The B7 (the V7 of Em) pulls toward Em, creating forward momentum even in this brief moment.

F major:  1-3-3-2-1-1
B7:       x-2-4-2-4-2
Em:       0-2-2-0-0-0

Dominant passing chords are particularly useful when you want the progression to feel purposeful and directed. They work well in upbeat songs and progressions that need energy.

How to Add Passing Chords to Your Progressions

The process is straightforward:

Step 1: Identify your main progression. Let’s say you have C - F - G - C.

Step 2: Find spots where chords are far apart. C to F is a jump of a fourth. That’s a natural place for a passing chord.

Step 3: Choose your passing chord type. Between C and F, you could use:

• Chromatic: Db major or C#m
• Diminished: Bdim or Cdim
• Diatonic (from the key): Dm

Step 4: Insert it on a weaker beat. C - (beat 4) Db - (beat 1) F. That passing chord gets less emphasis.

Step 5: Check voice leading. Make sure there’s smooth motion in the highest note of each chord. Ideally, notes move by step rather than jumping.

Let’s apply this to a real progression:

Original: Am - C - Em - G

Enhanced with passing chords: Am - B7 - C - Cmaj7 - Em - F#dim - G

Now we have:

• B7 as a passing chord into C (dominant preparation)
• Cmaj7 instead of plain C (extension, though not strictly a passing chord)
• F#dim passing into G (diminished passing)

The progression feels more sophisticated and has better forward motion.

Practical Examples

Example 1: A Simple Pop Progression

Original: C - F - C - G

With passing chords: C - Dm - F - G - C - Em - G

The Dm smooths C to F. The Em smooths G to C. Each insertion adds a slight lift without complicating the harmonic language.

Example 2: A Jazz-Influenced Progression

Original: Dm - G - Cmaj7 - Fmaj7

With passing chords: Dm - D#dim - Em - Ebaug - Fmaj7 - A7b9 - Cmaj7 - Dm7 - G7 - Cmaj7

(Note: This is heavily voiced, but you get the idea - diminished and dominant passing chords create flow.)

Example 3: A Blues Progression Smoothed

Original: C - C - F - C - G - F - C

With passing chords: C - Dm - C - Dm - F - F#dim - C - Cmaj7 - G7 - F7 - C

Each addition smooths a transition and adds sophistication without losing the blues feel.

Voice Leading Tips

The best passing chords maintain smooth voice leading. Here’s what that means:

When moving from one chord to the next, the highest note of each chord should move by step (a second) rather than jumping. This creates legato, smooth progressions.

For example:

• C major (highest note: G) to Dm (highest note: A) - the G moves up to A smoothly
• Dm (A) to F (A) - no movement, perfect

This is why chord voicing matters. The same progression voiced differently will have different voice leading qualities.

Practice this: Take a simple progression like C - F - G - C. Arrange each chord using different voicings, trying to keep the top note moving as little as possible. Then insert passing chords and maintain that smooth top-note motion.

Common Mistakes to Avoid

Don’t overcomplicate. One passing chord per two main chords is usually enough. Too many passing chords and your progression becomes harmonic soup rather than purposeful movement.

Don’t use passing chords on strong beats. If a passing chord lands on beat 1 or gets held for a full measure, it stops being a passing chord - it becomes a main harmony. That changes the feel entirely.

Don’t ignore rhythm. The passing chord should appear briefly, usually on the upbeat or a weak subdivision. If it gets the same rhythmic weight as main chords, the progression loses definition.

Don’t force chromatic movement everywhere. Sometimes the best passing chord is from the key itself (diatonic). Chromatic and diminished chords are powerful, but overuse them and they lose their effect.

Try This in Guitar Wiz

Open Guitar Wiz and go to Chord Library. Look up C major, F major, and G major. Practice switching between them smoothly, noticing where transitions feel clunky.

Now search the library for Dm, Bdim, and Db major. Experiment inserting these between your main chords. Notice how Dm (diatonic) feels different from Db (chromatic), and how Bdim creates a different character entirely.

Use Song Maker to build a simple progression like C - F - G - C. Record it, then create a new version with passing chords: C - Dm - F - G - C. Play both back-to-back and hear the difference.

Load the Chord Diagram view and manually find voicings for your main chords and passing chords that create smooth top-note voice leading. This hands-on practice accelerates your understanding.

Conclusion

Passing chords are a simple but powerful tool for writing more sophisticated progressions. They fill gaps, create momentum, and add smoothness without complexity. Whether you’re working with chromatic, diminished, or dominant passing chords, the concept is the same: move between main harmonies in a way that feels inevitable and musically satisfying.

Start with one type - chromatic passing chords are the most intuitive. Add them to your own progressions and listen to how they change the feel. Your ear will quickly develop an instinct for where passing chords belong and which type works best.
