The Skeleton of Every Song
Strip away the melody, the lyrics, the production — and what you have left is a chord progression. It's the harmonic foundation that everything else is built on. Understanding chord progressions is one of the highest-leverage skills a guitarist can develop.
The Nashville Number System
Professional musicians often use the Nashville Number System to describe chord progressions. Instead of naming specific chords, they use numbers to describe the relationship between chords in a key.
In the key of G:
- I = G major
- IV = C major
- V = D major
- vi = E minor
Why This Matters for Guitarists
When you understand that "Sweet Home Chicago" and "Johnny B. Goode" use the same I-IV-V structure, you can transfer what you learn in one song to dozens of others. You're learning patterns, not just songs.
Common Progressions to Know
| Progression | Examples |
|---|---|
| --- | --- |
| I-IV-V | Blues, rock, country |
| I-V-vi-IV | Pop, modern rock |
| ii-V-I | Jazz |
| I-vi-IV-V | 50s doo-wop, early rock |
| i-VII-VI-VII | Minor rock, metal |
At our Omaha studio, chord progressions aren't taught from a textbook. They're taught through songs you actually want to play. Theory and practice are always connected.
