The power chord is a two-note structure composed of the root and perfect fifth. Without a third, it's neither major nor minor, creating a powerful and neutral sound.

Theory
The power chord consists only of the root and perfect fifth (7 semitones). C5 = C-G, A5 = A-E. The absence of a third makes it harmonically ambiguous: it can function over major or minor chords. Often doubled at the octave (1-5-8), it's emblematic of rock and metal thanks to its massive sound with distortion. The perfect fifth reinforces natural harmonics, creating a full and powerful sound.
