A chord is technically 3 or more notes played simultaneously. Most chords have at least 3 notes. But a "power chord" is just 2 notes. the Root and the "5th"(also called "perfect 5th). So it is not actually a chord. the "5th" note being 7 semitones above the root. for example, if you are playing an "E" chord, then the power chord would be E and B. If it was a power "A" chord then it would be A and E. You can play more than 2 notes in the power chord by adding the octaves of the root and the 5th, but in rock music, it is usually just the 2 notes. Also called a bare fifth, open fifth or empty fifth. |
