Rock & Riffs
In a lot of rock music, the riff isn't the accompaniment — it IS the song. Power chords below, palm-muted and ready to loop.
The riff as the hook
A riff is a short, repeating musical figure that functions as a song's central idea — often introduced by guitar alone before the vocals or full band enter. That's different from a chord progression, which mainly supports a vocal melody rather than being the main event itself.
Power chords: the riff-writer's chord
A power chord is just a root and a 5th (no 3rd), which means it's neither clearly major nor minor — ambiguous, aggressive, and easy to slide around as one movable shape on the low strings. Because there's no 3rd to clash, the same shape works whether the surrounding part feels major or minor.
Palm muting for rhythm
Palm muting means resting the picking-hand edge lightly on the strings near the bridge to dampen their ring, producing a tight, percussive "chug." It's a hallmark of rock (and metal) rhythm guitar, turning single notes or power chords into something punchy and rhythmic rather than a wash of sustain.
Common questions
What makes a riff different from a chord progression?
A riff is a short, specific repeating musical figure (often built from a single-note or power-chord line) that functions as the song's central hook, while a chord progression is a more general harmonic backdrop.
Why are power chords so common in rock riffs?
They contain only the root and 5th (no 3rd), so they sound neither clearly major nor minor, they're easy to move as one shape anywhere on the low strings, and they sound huge through distortion.
What is palm muting?
Resting the edge of the picking hand lightly on the strings near the bridge while playing, which dampens the ring and creates a tight, percussive 'chug.'
Do I need distortion to play rock riffs?
No — the shapes and muting technique work on a clean tone too, but distortion (see Amps & Pedals 101) is what gives classic rock riffs their thick, aggressive sound.
Loop your own riff
Melody Monkey lets you build and loop a riff, then layer chords and drums around it.
