The Role of Chord Progressions in Rock Music
Chord progressions serve as the backbone of many rock songs. They create the emotional framework and guide the listener through the musical narrative. Classic progressions like I–IV–V or ii–V–I are common, but rock musicians often experiment with variations to produce unique sounds.

- Modal interchange: Borrowing chords from parallel modes to add color.
- Power chords: Simplified chords that emphasize root and fifth, creating a strong, driving sound.
- Vamp and pedal points: Repeating a chord or note to build tension or focus on a particular harmonic area.
