The "Invincible Eight Chords" – A Versatile Progression for Many Songs!

You might have come across claims online like: “This song can be played with just the ‘Invincible Eight Chords.’”

This often leads to the question: What exactly are the ‘Invincible Eight Chords’?

Interestingly, there’s rarely a clear, definitive answer.

After analyzing the chord progressions of hundreds of popular songs, I’ve come to understand that the so-called “Invincible Eight Chords” generally refer to an 8-bar repetitive chord progression:

| C | G | Am | Em | F | C | F | G |

This 8-bar progression is essentially the chord sequence of the famous Canon. Sometimes, these chords can be substituted or altered, for instance:

| C | G/B | Am | G | F | Em | Dm | G |

1. Substituting Root Notes or Chord Inversions

In the second measure, you can replace the root note of the G chord with B (creating a G/B). This creates a descending bass line in the background, which can add a smooth, flowing effect to the progression.

2. Substituting Chords

You can also make substitutions to create variations:

Replace Em in the fourth measure with G.
Replace C in the sixth measure with Em.
Replace F in the seventh measure with Dm.

These changes not only create a descending bass line but also result in a smoother harmonic progression. You’ll notice that the original chord and its substitute often share similar notes, which is why the substitution works so seamlessly.

3. When to Substitute Chords?

When deciding whether to substitute a chord, you must consider the melody of the song.

For example, if the melody in the seventh measure includes the notes 4 or 6 (according to the scale), you can use either F or Dm as the corresponding chord. Which one should you choose? Try both! Either could work depending on the musical context.

However, when transcribing or covering a song, it’s best to stay true to the original chord progression to avoid potential mistakes or criticism for incorrect chords.

4. Using Extended or Altered Chords for Richer Textures

To add more emotional depth or harmonic tension, you can incorporate advanced chords like seventh chords, suspended chords, add9 chords, or secondary dominants. For example:

| Cadd9 | G/B | Am | Am7/G | Fmaj7 | C/E | D7 | G7 |

Such variations can make the progression sound more colorful and dynamic, offering greater creative potential for accompaniment or arrangement.

5. Practicality of the Invincible Eight Chords

At first glance, the “Invincible Eight Chords” may seem overly simplistic. However, with different chord substitutions, rhythmic variations, tempo changes, and playing techniques, this progression can be adapted to accompany a wide variety of songs.

For example, consider the music of Mayday (五月天)—masters of using simple, repetitive progressions to create unforgettable hits. While many musicians may possess exceptional technical skills, few can compose a catchy, memorable song with such ease. This demonstrates that writing great songs is not just about technical ability—it’s also about creativity and intellect.

6. Writing Songs with Simple Progressions

When discussing the “Invincible Eight Chords,” it’s worth noting that folk music often relies on even simpler progressions, known as the "Invincible Four Chords":

| C | Am | Dm | G | or | C | Am | F | G |

Additionally, many classic international hits use just three chords. Consider the 12-bar blues, which forms the basis of countless iconic songs.

But here’s the real question: How many people can actually compose a great song using such simple progressions?

Rather than dismissing a musician by saying, “All their songs use the same chord progressions,” why not ask yourself, “Why can they write great songs while I cannot?”

So, instead of underestimating simple progressions, embrace them as a tool for creativity. After all, it’s not the complexity of the chords that matters—it’s how you use them to craft meaningful and memorable music. Keep practicing, experimenting, and most importantly, creating! 🎸
