The Magic of 4 Chords: How Thousands of Hits Use the Same Progression

It never fails to amaze me that so many phenomenal songs throughout the history of popular music have been written using just four simple chords.

When you sit down and really think about it, what is even more astounding is that brand-new, completely individual tracks are written every single day using that exact same sequence. Yet, they don’t all sound the same. You can take the identical four chords, play them in the same order, at the exact same tempo, and yet, if you overlay a different vocal melody, alter the strumming pattern, or shift the rhythmic accents, it transforms into something entirely unique.

The Formula: The I - V - vi - IV Progression

In music theory, this magic sequence is known as the I - V - vi - IV progression. To put that into real-world terms, if we are playing in the key of G Major, the chords are:

G  ·  D  ·  Em  ·  C

There is no better online example of this harmonic phenomenon than the brilliant, hilarious video by The Axis of Awesome, an fantastic Aussie musical comedy trio. Sure, they have transposed a few of the tracks into the same key to seamlessly string them together, but it perfectly illustrates just how many infinite pop possibilities are hidden inside four simple chords.

Stripping It Back Even Further

If you thought four chords was minimalist, plenty of legendary tracks don't even bother stretching that far. Off the top of my head, here are some incredibly famous tunes that rely on just three, two, or even a single chord:

Famous 3-Chord Songs

• "Abracadabra" – Steve Miller Band (Am, Dm, E7)
• "Rock Around the Clock" – Bill Haley & His Comets (A, D, E)
• "All Along The Watchtower" – Bob Dylan / Jimi Hendrix (C#m, B, A)
• "Bad Moon Rising" – Creedence Clearwater Revival (A, D, G)
• "Chasing Cars" – Snow Patrol (A, E, D)
• "La Bamba" – Richie Valens / Los Lobos (C, F, G)
• "Breakfast at Tiffany's" – Deep Blue Something (A, D, G)
• "Red Red Wine" – Neil Diamond / UB40 (C, D, G)
• "Wild Thing" – The Troggs (A, D, E)
• "All Shook Up" – Elvis Presley (A, D, E)

Famous 2-Chord Songs

• "Eleanor Rigby" – The Beatles (Em, C)
• "Jambalaya (On the Bayou)" – Hank Williams (G, D7)

The 1-Chord Masterclass

• "Get the Party Started" – Pink (Built entirely around a driving, hypnotic Bm groove)

Why Does This Work?

As guitarists, this is incredibly liberating news. It means you don't need a PhD in jazz fusion harmony to write an engaging piece of music or have a great jam session. Songwriting is all about context. By changing your dynamics (playing quietly in a verse and loudly in a chorus) or altering your picking style (switching from a smooth acoustic fingerstyle to an aggressive electric rock rhythm), you can squeeze an entire afternoon of fun out of just a couple of chord shapes.

Now that you know the secret behind the curtain, grab your guitar, fire up your metronome, and go try these progressions out for yourself!
