Chord Progressions

A single chord is a color. A chord progression is a story: it sets up tension and releases it, again and again. Thousands of hit songs share the same handful of progressions. Learn why they work and you can write your own in minutes, in any key and any genre.

What is a Chord Progression?

A chord progression is a series of chords played in order, usually repeating. Most modern songs loop a progression of 4 chords, often one chord per bar, so the pattern lasts 4 bars.

Progressions are written with Roman numerals, which you met in Chords. Uppercase is major, lowercase is minor. Because numerals describe the position in the key rather than the note names, one progression works in every key.

One progression, three keys

Numerals: I V vi IV C major: C G Am F G major: G D Em C D major: D A Bm G

Same shape, same emotion, just higher or lower. That's why producers think in numerals.

Chord Functions: Home, Away, Tension

Each chord in a key has a job, called its function. There are three main functions:

Function	Chords (major key)	Feels like
Tonic	I (also vi and iii)	Home. Stable, resolved, at rest
Subdominant	IV (also ii)	Leaving home. Movement, a gentle lift
Dominant	V (also vii°)	Tension. Strongly wants to go back home

The most basic story in music is home → away → tension → home: I → IV → V → I. Almost every progression is a variation on this idea.

Why does V pull so strongly to I? In C major, the G chord contains B, which is one semitone below C. That note, the leading tone, "wants" to rise to C. Moving from V to I is called a cadence, the musical version of a full stop.

Note

Ending on V instead of I leaves the listener hanging, like a question. Songwriters often end a verse on V so the chorus feels like the answer.

Famous Progressions

I – V – vi – IV (the "pop progression")

This is probably the most used progression in modern pop. In C major: C – G – Am – F. It sounds hopeful and uplifting, with a touch of emotion from the vi chord. You can hear it in songs like Journey's "Don't Stop Believin'" and The Beatles' "Let It Be".

vi – IV – I – V (the "emotional" version)

The same four chords, starting on vi: Am – F – C – G. Starting on the minor chord makes it feel more emotional and bittersweet. It's everywhere in pop ballads and emotional EDM.

ii – V – I (the jazz progression)

In C: Dm7 – G7 – Cmaj7. It moves subdominant → dominant → tonic in the smoothest way possible, so it's the core of jazz and shows up in R&B, neo-soul and lo-fi. Use seventh chords to get the authentic sound.

i – VI – III – VII (the "epic minor" progression)

In A minor: Am – F – C – G. Dramatic and powerful, popular in film trailers, EDM, trap and rock. It uses the same chords as the pop progression but starts and ends around the minor chord, so it feels darker.

The demo menu has more presets, including I – vi – IV – V (the 1950s doo-wop progression), i – iv – v – i, and I – IV – V – IV (rock). Try them all.

The 12-bar blues

The 12-bar blues is a 12-bar form built on just three chords: I, IV and V. It's the foundation of blues, early rock and roll and a lot of funk.

12-bar blues in A (one chord per bar)

Bars 1–4: A A A A (I I I I) Bars 5–8: D D A A (IV IV I I) Bars 9–12: E D A E (V IV I V)

The last bar (V) is called the turnaround: it sends you back to the start. Blues players usually play every chord as a dominant 7th (A7, D7, E7) for that bluesy bite. A common variation puts IV in bar 2 (the "quick change").

How to Write Your Own

You don't need to copy famous progressions. Follow these steps and you'll get something that works every time.

Pick a key and a mood. Major for bright, minor for dark. If in doubt, use C major or A minor (all white keys).
Start on the tonic (I or i) to establish home. Or start on vi or IV for a more unsettled opening.
Move away with a subdominant chord (IV or ii).
Build tension with a dominant chord (V).
Resolve back to the tonic, or leave it hanging on V to loop back to the start.
Swap one chord to make it yours: replace I with vi, or IV with ii. Chords with the same function can usually substitute for each other.
Add color: turn some chords into 7ths, sus or add9 chords.

Building a progression step by step (C major)

Basic story: C F G C I IV V I Swap I → vi: C F G Am I IV V vi Swap IV → ii: C Dm G Am I ii V vi Add color: Cmaj7 Dm7 G7sus4 Am7

Each line still makes sense harmonically, but each one has a different flavor.

Producer tip

A familiar progression is not a weakness. Listeners don't notice that two songs share I – V – vi – IV. They notice the melody, the sounds and the rhythm. Spend your energy there, and let the progression be simple.

Borrowed Chords

A borrowed chord is taken from the parallel key: the major or minor key with the same root. C major borrows from C minor and vice versa. This is also called modal interchange. One borrowed chord can add surprise and emotion to an otherwise ordinary progression.

Borrowed chord (in C major)	Notes	Effect
iv (Fm instead of F)	F A♭ C	Bittersweet, nostalgic. Classic move: F → Fm → C
♭VII (B♭)	B♭ D F	Rock and anthem feel. "I – ♭VII – IV"
♭VI (A♭)	A♭ C E♭	Big, cinematic lift. Often ♭VI – ♭VII – I
♭III (E♭)	E♭ G B♭	Bold, surprising color

It works the other way too. In a minor key, using a major V (E major in A minor) instead of the minor v gives a much stronger pull back home. That's why so many minor-key songs use it.

Harmonic Rhythm

Harmonic rhythm is how often the chords change. The same chords can feel very different depending on their timing.

Slow (one chord every 2 bars or more): calm, spacious, hypnotic. Common in ambient, deep house and many trap beats.
Medium (one chord per bar): the default for most pop and EDM.
Fast (two or more chords per bar): busy and energetic. Common in jazz, gospel and fast punk.

You can also change harmonic rhythm within a song, for example one chord per bar in the verse and two per bar in the pre-chorus to build energy.

Rhythm inside each chord matters as well. Holding a pad for the whole bar feels smooth; stabbing short chords on the offbeats feels like house or reggae; pushing a chord change one 8th note early (an anticipation) adds forward motion. See Rhythm & Tempo.

Progressions by Genre

These are common choices, not rules. Each is shown in an example key.

Genre	Typical progression	Example	Notes
Pop	I – V – vi – IV	C – G – Am – F	One chord per bar
Emotional EDM / future bass	vi – IV – I – V	Am – F – C – G	Often with lush 7ths and sidechain pumping
Trap / drill	i – VI or i – ♭II	Am – F, or Cm – D♭	Often just 2 chords, slow harmonic rhythm, dark minor keys
Lo-fi / neo-soul	ii7 – V7 – Imaj7 or IVmaj7 – iii7 – vi7	Dm7 – G7 – Cmaj7	Extended chords (7ths and 9ths)
Deep house	i7 – iv7 or i7 – VII	Am7 – Dm7	Minor 7th chords, often in stabs
Rock	I – IV – V or I – ♭VII – IV	E – A – B, or D – C – G	Power chords, borrowed ♭VII
Blues	12-bar blues (I – IV – V)	A7 – D7 – E7	Dominant 7ths on every chord
Cinematic / epic	i – VI – III – VII	Am – F – C – G	Slow, big, with ♭VI – ♭VII – I lifts

Once you have a progression, the next steps are a melody on top (Melody Writing) and a bassline underneath (Basslines).

Try it in your DAW

Set the tempo to 100 BPM and create an instrument track with a piano or pad.
Draw I – V – vi – IV in C major (C – G – Am – F), one chord per bar, as triads around C4.
Duplicate the 4 bars and reorder them to vi – IV – I – V. Compare the mood.
Replace the F in bar 4 with Fm (lower the A to A♭). Hear the borrowed iv chord.
Change the harmonic rhythm: make each chord 2 bars long, then try 2 chords per bar.
Add a bass track playing just the root of each chord, one octave below C3.

In C major, the I – V – vi – IV progression is C – G – – F.

The chord function that creates tension and wants to resolve home is called the .

The 12-bar blues uses three chords: I, IV and .

1. Which chord has the dominant function in a major key?

V is the dominant. It contains the leading tone, which pulls strongly back to the tonic (I).

2. What is I – V – vi – IV in G major?

G – D – Em – C
G – C – Am – D
C – G – Am – F
G – D – Am – C

In G major: I = G, V = D, vi = Em, IV = C.

3. What is a borrowed chord?

A chord copied from another song
A chord with no third
A chord played by a different instrument
A chord taken from the parallel major or minor key

Borrowing (modal interchange) takes chords from the key with the same root but the opposite mode, like Fm (iv) in C major.

4. What does "harmonic rhythm" describe?

The drum pattern under the chords
How often the chords change
The tempo of the song
How loud the chords are

Harmonic rhythm is the rate of chord changes: one per bar, one every two bars, two per bar and so on.

5. In the 12-bar blues in A, which chord is in bar 9?

A (I)
D (IV)
E (V)
F#m (vi)

Bars 9–12 go V – IV – I – V. In A that's E – D – A – E.
