power chord
A chord consisting of only the root and fifth (and often the octave), without a third, producing a neutral, heavy sound used extensively in rock and metal.
In Depth
The reason power chords work through distortion but full chords sound muddy is pure physics: the perfect fifth (3:2 ratio) generates harmonious overtones through distortion, while thirds create dissonant intermodulation products.
