I5–IV5–V5
The I5–IV5–V5 progression is the power chord version of the classic I–IV–V, stripping away the thirds to leave only roots and fifths. Without major or minor quality, these chords gain a raw, neutral power that sounds massive through distortion. This is the foundation of rock, punk, and metal rhythm guitar, where harmonic ambiguity and sheer energy matter more than tonal color.
