Power chords, or “5” chords as they are often called, are an essential part of any rock guitarist’s arsenal. They are constructed of the 1st, 5th and 8th notes of the major scale, because the 8th note in a scale is the same as the 1st, just an octave higher. In fact, it’s often called “the octave” instead of the 8th. A power chord only contains two different notes, unlike a major or minor chord, which contains three.
The extra note in a major chord is the 3rd note from the major scale and the extra note in minor chord is the 3rd note from the minor scale. Below demonstrates the construction of these different chords:
The third note in a chord dictates whether it is major or minor. Because a power chord has no third, it is therefore neither major nor minor. This gives the chord its raw and powerful characteristics.
The late Link Wray (1929 – 2005) is credited for inventing power chords. He found that when adding distortion to a major or minor chord a dissonant sound was produced, by removing the 3rd the dissonance was lost with the chord still maintaining its diatonic functionality.
Below are the two most popular shapes for playing power chords:
The note your first finger is on names the chord. If you played the 6th string root shape on the first fret it would be an F5 because your first finger would be on an F. In order to move the shape and play different chords we need to know all of the notes down the 6th string:
And the 5th string:
Below are sets of exercises that consolidate all the information covered so far and assist in improving orientation along the two strings.
Start by trying all the exercises on the 6th string. As soon as there is little hesitation when changing from chord to chord try the exercises on the 5th string.
With the shapes learnt and the strings explored its time to put everything together. Below are some songs using Power chords, hopefully something for everyone.
Power chords are usually played with down strokes, this helps co-ordination making it easier to strike just three strings, it keeps the right hand in the same position allowing it to be used to mute unwanted strings or apply palm muting.

I hope this article has been of interest. There is a lot here to get your head around so take it slowly, just by knowing how the notes progress up a string (remembering that E and B do not have sharps) it is now possible to work out any note on the guitar. And that’s something many players cannot do!
