The power guitar chords are very simple guitar chord(power probably refers to the tight powerful sound that can be produced by playing powerchords – characteristic of heavy rock and metal guitar playing). The power chords consist of notes played across just two or three strings and you could argue that the powerchord is not even a real guitar chord(power chords consist of less than 3 notes, so technically cannot be regardeed as a chord). The power chord consists of a root note and the 5th (an additional root note one octave higher can also be played) and power chords are named accordingly – for example if the root note happens to be an A, then the power chord is called A5 (A for the root note and 5 for perfect 5th note – for more details on the musical theory of intervals, here’s a Wikipedia article that may help). Power chords are therefore easy to play and are widely adopted by rock guitarists since the finger positions can remain the same and be moved around the neck of the guitar as you’ll see from the chord box examples below. Note that the powerchords shown below (A5, A, B5, C5, D5, D, E5, E, F5 and G5 powerchords) are one and two-fingered powerchords. There are three-fingered powerchords as well and these will be included soon. I’ll also try to prettify up the way these chords are displayed make it more like a power chord chart – for now though, you’ll have to make do with an ugly list as it’s better than nothing.

My advice is that whilst power chords are easy to learn and play, you should not be tempted to learn only power chords as this will severely limit your development as a guitar player. You should in addition try to gain a good understanding of both open chords and barre chords in order to maximise your versatility as a guitar player.
