Power Chord Chart
These chords sound especially well with a distortion or an overdriven electric guitar, where most other chords like major, minor or seventh are too noisy.
In guitar tabs and song books power chords are usually indicated by a digit 5 like so: C5, A5, F5...
In this chart I included two versions for each chord, located in different parts on the fingerboard.
The numbers in the pink rectangles designate the fret from which you place the fingers.
