Progressions

Four chords. A huge number of songs.

A chord progression is just an order of chords. Learn four common orders and you can recognise — and play — a large part of the music you already listen to. Pick a key, hear the progression, then play it yourself.

Make it yours

Pick a key and hear it.

The Roman numerals stay the same; the chords change with the key. Start in C, then move the same progression somewhere else.

Notes use the spelling of the selected key: C♯ major contains E♯, the same fret as F. The diagrams use the lowest available shape. Some keys put a chord above the 10th fret; use the capo chart if a song needs an easier position.

What is a chord progression?

A progression is a sequence of chords that belongs to one key. The key gives you seven chords, built on the seven notes of its scale. Instead of memorising every chord name, you can number them with Roman numerals: I, ii, iii, IV, V, vi and vii°.

Uppercase means a major chord; lowercase means minor. In C major, I is C, ii is Dm, iii is Em, IV is F, V is G, vi is Am and vii° is Bdim. The same numbers work in every major key, which is why a progression can move from C to G without changing its character.

How to read the numbers

Roman	In C	Quality	Feel
I	C	major	home
ii	Dm	minor	prepares the V
iii	Em	minor	soft, in-between
IV	F	major	lift
V	G	major	tension, wants I
vi	Am	minor	sad relative minor

The four progressions

I – V – vi – IV

The pop progression

The I chord feels like home, V pulls away from it, vi turns the mood minor without leaving the key, and IV opens the door back home. It is the most common four-chord loop in modern pop because it keeps moving without ever feeling lost.

Try it with

· Let It Be — C–G–Am–F
· With or Without You — D–A–Bm–G
· Someone Like You (verse) — A–E–F♯m–D

Start with one downstroke per chord. When that is steady, try the D–DU–UDU strumming pattern on the same four chords.

I – IV – V

The three-chord backbone

Three major chords, no minor, no ambiguity. I is home, IV is the lift, V is the tension that wants to resolve back to I. Folk, country, blues and campfire songs are built on this triangle.

Try it with

· Wild Thing — A–D–E
· Twist and Shout — D–G–A
· This Land Is Your Land — G–C–D

Play I–IV–V–IV and listen to how V leans back to I. Then try starting on IV instead of I; the same three chords feel completely different.

vi – IV – I – V

The emotional loop

Starting on vi makes the progression feel melancholy before it resolves to I. The IV and V then lift the chorus without changing key. It is the same four chords as I–V–vi–IV, just rotated so the minor chord comes first.

Try it with

· Demons (chorus) — Bm–G–D–A
· Grenade (verse) — Dm–B♭–F–C
· Numb — F♯m–D–A–E

If a song feels sad but not slow, this is often why. Try the same four chords in a different order and notice how the emotional centre moves.

ii – V – I

The jazz cadence

The ii chord prepares the V, and the V resolves to I. It is the strongest three-chord cadence in tonal music, and jazz standards use it at the end of phrases again and again. The same shape works as a turnaround in pop and soul.

Try it with

· Fly Me to the Moon (turnaround) — Dm–G–C

Use the ii and V as preparation, not as a destination. Land on I and let it ring for a full bar before starting again.

How to practise a progression

Choose a key you can already play — C or G is a good start.
Play one downstroke per chord, four beats each. Do not add a strumming pattern yet.
Count out loud: 1, 2, 3, 4. Change chord on beat one.
When the change is clean, add the D–DU–UDU pattern or a metronome.
Move the same progression to another key only when the first key feels automatic.

If the changes are slow, use the one-minute change trainer. If a chord buzzes, use the clean-chord checklist before adding speed.

Why the same four chords keep working

These progressions balance home, tension and release. I feels like home; V creates tension; vi and IV add colour without leaving the key. The order changes the emotional emphasis, but the underlying job of each chord stays the same. That is why a song can feel familiar the first time you hear it.

It also means you do not need to memorise hundreds of songs chord by chord. Recognise the progression, find the key, and the shapes follow. This is the skill that turns chord diagrams into music.

What to do next

Pick one progression and one key. Play it for five minutes a day for a week. Then try the same progression in a second key. If a song uses a capo, use the capo chart to keep the shapes you know. If you want to see how keys relate, open the circle of fifths.

Frequently asked questions

What is the I–V–vi–IV progression?

It is a four-chord loop built on the first, fifth, sixth and fourth chords of a major key. In C major it is C–G–Am–F. It is common in pop because it moves away from home and resolves without ever leaving the key.

What is the 1–4–5 progression?

The first, fourth and fifth chords of a key — in C: C–F–G. It is the backbone of folk, country, blues and many campfire songs. The V chord creates tension that wants to resolve back to I.

What does ii–V–I mean?

The second, fifth and first chords of a key — in C: Dm–G–C. The ii prepares the V, and the V resolves to I. Jazz standards use this cadence at the end of phrases constantly.

Can I use a capo?

Yes. A capo lets you keep easy open shapes and move the song to a higher key. Use the capo chart to find the shape and fret that produce the key you need.

Do I need barre chords for these progressions?

Not for C, G, D, A, E, Am, Em and Dm. Some keys need F, Bm or another barre chord; the diagrams show the lowest shape available. Start in C or G if you are new.

What key should I start in?

C major. Its I–V–vi–IV is C–G–Am–F, which uses four beginner-friendly shapes. G major (G–D–Em–C) is the next easiest.
