Module 04 · Diatonic Harmony: How Chords Work TogetherLesson 4.3
The Progressions That Run Popular Music
A small set of chord progressions accounts for most of the songs you know. Learn them as sounds.
The idea
Learn these as sounds, not as trivia. Each row is one sound you should be able to recognize and play in any key.
| Progression | Sound and famous examples |
|---|---|
| I – V – vi – IV | The pop axis: “Let It Be”, “No Woman, No Cry”, half the radio |
| vi – IV – I – V | The same loop starting on the minor chord: “Zombie”, “Numb” |
| I – IV – V (– IV) | Rock and roll primary colors: “Wild Thing”, “La Bamba” |
| I – vi – IV – V | The 1950s doo-wop loop: “Stand By Me” |
| ii – V – I | The engine of jazz. In pop, the smooth landing at the end of a pre-chorus |
| 12-bar blues | Blues, early rock, countless metal boogies |
| I – ♭VII – IV | Mixolydian rock: “Sweet Home Alabama”, “Sympathy for the Devil” |
| i – ♭VII – ♭VI (– ♭VII) | The Aeolian descent: “All Along the Watchtower”, the outro solo of “Stairway to Heaven” |
| i – iv – V | The minor lament with the harmonic-minor sting |
Pick a progression, pick a key, and loop it. Edit the numerals to try your own:
The 12-bar blues is a progression and a form at once:
| Bars 1–4 | Bars 5–8 | Bars 9–12 |
|---|---|---|
| I – I – I – I | IV – IV – I – I | V – IV – I – (V) |
The V in the last bar is the “turnaround”: it sends you back to the top.
The same four chords, heard two ways. vi – IV – I – V and i – ♭VI – ♭III – ♭VII are the same chords. In “Zombie” the loop is Em – C – G – D. If you hear G as home, it is vi – IV – I – V in G major. If you hear Em as home, and in that song most people do, it is i – ♭VI – ♭III – ♭VII in E minor. Lesson 4.4 looks at minor keys in detail.
Loop or journey. Modern pop often loops one four-chord cell for the whole song, and the contrast comes from melody and arrangement. Classic songwriting travels: the verse progression differs from the chorus progression, and cadences steer the form. Both are valid tools. Choose deliberately.
On your instrument
- Play every progression in the table in two keys on guitar, and once on piano or with the player.
- Sing the roots while you play. This is the fastest way to learn to recognize progressions by ear.
- Change the harmonic rhythm. Play I – V – vi – IV with one bar per chord, then with two chords per bar, then with two bars per chord. The same progression becomes a punk song, a ballad and an anthem.
Worked example
From loop to journey. Start with the loop vi – IV – I – V in G: Em – C – G – D.
An 8-bar journey with the same flavor:
| Bar | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 |
|---|---|---|---|---|---|---|---|---|
| Chord | Em | C | G | D | Em | C | Am | D → G |
| Function | T | S | T | D | T | S | S | D → T |
Bars 1 to 4 are the loop. Bars 5 and 6 repeat its start. Bar 7 goes somewhere new: Am, the ii chord, which the loop never used. Bar 8 delivers a real authentic cadence, D to G. The section now has a beginning, a departure and an arrival.
Exercises
- The ten-progression sprint. In 30 minutes, write ten different four-chord loops as numerals plus one key each. No quality control: volume is the point. Star the two best and keep them for Module 6.
- Pick one starred loop. Write an 8-bar journey version: keep its flavor, add a departure and a real cadence.
- Play a 12-bar blues in E and in A with power chords, then with the shell voicings from lesson 3.2.
- Use the trainer below until you can name these progressions by ear.
Common mistakes
- Collecting progressions instead of hearing them. A list of fifty progressions is useless if you cannot recognize five by ear.
- Believing a progression makes a song. Thousands of songs share I – V – vi – IV. The melody, rhythm and arrangement make them different.
