The I-V-vi-V progression, known as the Axis of Awesome, is sometimes critiqued for contributing to homogenization in music, as highlighted in comedic sketches like Axis of Awesome’s “Four Chord Song,” which mashes up dozens of hits using this exact progression. Yet, defenders argue its universality allows for creative variation—through rhythm, tempo, instrumentation, or extensions like adding sevenths (e.g., IVmaj7)—preventing staleness.
The I-V-vi-IV progression is one of the most common in modern pop and rock music, often evoking emotional resonance due to its balance of tension and resolution. It appears in countless songs, suggesting its effectiveness stems from simple, memorable harmonic movement rather than complexity.
Harmonic Function:
In major keys, it starts on the tonic (I) for stability, moves to the dominant (V) for tension, then to the relative minor (vi) for emotional depth, and resolves to the subdominant (IV) for a sense of uplift—though interpretations vary slightly among theorists.
Potential Drawbacks:
While versatile, overuse can make songs feel formulaic; however, evidence leans toward it being a reliable framework for catchy melodies without implying it’s the only option.
Variations and Context:
It works well in keys like C major (C-G-Am-F), but adaptations in minor keys or with extensions add nuance, highlighting its flexibility across genres.
Basic Structure and Why It Works
This progression, often called the “pop-punk progression” or “four-chord song,” cycles through four chords in a major key: the tonic (I), dominant (V), submediant (vi), and subdominant (IV).
For example, in C major, it’s C-G-Am-F. Research suggests its appeal lies in diatonic harmony—all chords from the same scale—creating smooth voice leading where notes flow naturally between chords. The V to vi shift introduces a deceptive cadence feel, adding surprise and emotional pull, while IV back to I (if looped) provides resolution. It’s not inherently “happy” or “sad” but adaptable, as seen in upbeat tracks or ballads.
Common Examples in Songs
Songs like “Let It Be” by The Beatles (verses), “With or Without You” by U2, and “Someone Like You” by Adele use this sequence, demonstrating its cross-era popularity. In rock, Journey’s “Don’t Stop Believin'” exemplifies it in E major (E-B-C#m-A). These examples show how the progression supports strong melodies without overpowering them.
Practical Tips for Musicians
If composing, start in an easy key like G major (G-D-Em-C) to experiment. Add seventh chords (e.g., V7) for more tension, or invert chords for variety. Tools like chord charts can help visualize—see examples online for diagrams.
Deep Dive Into I-V-vi-IV
The I-V-vi-IV chord progression stands as a cornerstone of contemporary music theory, particularly in popular genres, due to its structural simplicity and emotional versatility. Rooted in diatonic harmony, this sequence leverages the fundamental relationships between scale degrees in a major key to create a loop that feels both familiar and engaging.
In a typical major key, the chords correspond to the first (tonic, I), fifth (dominant, V), sixth (submediant, vi), and fourth (subdominant, IV) degrees of the scale. For instance, in the key of C major, this translates to C major, G major, A minor, and F major.
This arrangement is not arbitrary; it draws on centuries-old principles of tonal music, where the tonic provides stability, the dominant builds anticipation, the submediant offers a modal shift toward minor tonality for introspection, and the subdominant facilitates a gentle return or extension of the phrase.
Harmonically, the progression’s effectiveness can be analyzed through the lens of functional harmony, a concept popularized by theorists like Hugo Riemann in the late 19th century.
The I chord establishes the key’s tonal center, acting as a “home base.” The move to V introduces dominant function, creating tension via the leading tone (the seventh scale degree) that naturally resolves back to I.
However, instead of resolving directly, the progression diverts to vi, which shares two notes with I (in C major: A and C in Am, versus C, E, G in C), allowing for smooth voice leading while injecting a relative minor flavor that evokes melancholy or depth. This vi chord functions as a tonic substitute in some analyses, borrowing from the parallel minor mode. Finally, the IV chord provides subdominant function, often seen as a pre-dominant that softens the return to I, creating a plagal cadence feel when looped (IV-I). This cycle avoids strong authentic cadences (V-I) within the loop, which contributes to its “endless” quality, making it ideal for verse-chorus structures in pop music.
From a voice-leading perspective, the progression minimizes large leaps in melodic lines. In C major, moving from I (C-E-G) to V (G-B-D) shares the G note; V to vi (A-C-E) shares no direct notes but allows common tones in inversions; vi to IV (F-A-C) shares A and C. This efficiency reduces dissonance and enhances singability, a factor in its widespread adoption. Psychological studies on music perception, such as those referencing schema theory, suggest that listeners anticipate these movements based on exposure to Western tonal music, leading to a satisfying blend of predictability and subtle surprise.
The progression’s history traces back to earlier forms, evolving from Baroque and Classical era sequences like the circle of fifths, but it gained prominence in the 20th century with rock and pop.
In minor keys, a parallel version (i-VI-III-VII, like Am-F-C-G) mirrors it, showing modal interchange possibilities.
Examples abound across decades: The Beatles’ “Let It Be” uses it in the verse for a hymn-like quality; U2’s “With or Without You” builds atmospheric tension; Adele’s “Someone Like You” employs it for emotional balladry; Green Day’s “When I Come Around” showcases its punk edge; and Taylor Swift’s “Shake It Off” adapts it for upbeat pop. These illustrate how the progression supports diverse moods, from triumphant (Journey’s “Don’t Stop Believin'”) to reflective (Ed Sheeran’s “Perfect”).
For practical application, musicians can experiment with inversions to alter bass lines—e.g., I (root), V (second inversion), vi (first), IV (root)—or borrow chords from parallel modes for color. In composition, it pairs well with pentatonic melodies, as the chords align with scale notes, minimizing clashes.

| I-V-vi-IV | “Don’t Stop Believin'” | Baseline: Balanced tension-release. |
| vi-IV-I-V | “Save Tonight” (Eagle-Eye Cherry) | Starts on minor for somber intro; same chords rotated. |
| I-vi-IV-V | “Stand By Me” (Ben E. King) | Ends on V for stronger pull back to I. |
| ii-V-I | Jazz standards like “Autumn Leaves” | More sophisticated; focuses on resolution over loop. |
