Power chords and songwriting
A few power chords can carry a huge chorus. Try these seven loops, then change the rhythm, muting, and register to make a guitar part of your own.
All examples use standard tuning and four power-chord positions. A power chord contains a root and fifth, often with the root doubled. It has no third, so major or minor character comes from the surrounding harmony and melody.
Start at 70–90 BPM, one chord per bar, with even quarter notes. For a tighter verse, palm-mute near the bridge. For a chorus, release the mute and let the chords ring. Raise the tempo only when the changes stay clean.
The numeral labels describe the intended harmonic setting. They do not add a major or minor third to the power-chord shapes.
G5 – D5 – E5 – C5
I–V–vi–IV in G major. Keep the verse restrained, then open the same chords into steady eighth notes for the chorus.

E5 – C5 – G5 – D5
vi–IV–I–V in G major. Begin the phrase around E, then let G feel like a lift in bar three. A melody using G natural over E5 makes the minor color clear.

G5 – C5 – D5 – C5
I–IV–V–IV in G major. Give D5 a stronger accent, then make the last C5 shorter to leave a breath before G5 returns.

G5 – E5 – C5 – D5
I–vi–IV–V in G major. Try a light picked verse and a full strummed chorus. Keep the chord durations fixed so the rhythm creates the contrast.

E5 – D5 – A5 – E5
I–♭VII–IV–I around E. D is the lowered seventh relative to E major. Try an E-centered melody with G♯ for a major or Mixolydian color, then compare G natural for a rougher minor/blues edge.

A5 – C5 – D5 – E5
i–♭III–iv–V in an A-minor setting. Use C natural for the minor color; G♯ over the final E5 can pull strongly back to A. The power chords themselves leave those thirds unstated.

E5 – C5 – A5 – B5
i–♭VI–iv–V in an E-minor setting. A melody can use G natural over E5, then D♯ over B5 to push into the next E. Keep those notes deliberate rather than running one unchanged scale.

The same chord sequence can support both sections. If they still feel identical, change the density, melody, or drum pattern before adding more chords.
Open a progression in StrumForge, choose comfortable power-chord voicings, and set a tempo below your limit. Keep the groove steady while you practice your own palm-muted part. Add speed in small steps after several clean loops.
Free four-chord generation has a daily allowance. Pro adds more progression lengths, advanced rhythm controls, favorites, and dedicated practice tools.
