Power Chords
   

 

Power chords provide the foundation for rock rhythm guitar. A power chord is a two-note chord voicing, usually played on the bass (low) strings of the guitar. The rhythm guitarist's power chords combine with the bass guitarist's part to supply a bottom end to the music that is fast and hard driving.

Power Chord Construction

All Power Chords are built on two notes; The root ( the name of the chord) and the fifth note of the root's scale.

If we number each consecutive note from C to C we get:

C
D
E
F
G
A
B
C
1
2
3
4
5
6
7
8
Root
Fifth
Octave

 

C + G = C5
1 + 5 = Power Chord

There are three basic power chord forms:

root 6

root 5

root 4

That means that the root starts on string 6, 5, or 4. Most guitar chords can be constructed from these three basic forms.
