A power chord is a two-note chord made of a root and a perfect 5th, seven semitones above the root, with an optional octave of the root on top. A C5 power chord is C and G (plus C an octave higher), and because it has no 3rd it is neither major nor minor.
What is a power chord?
A power chord is the simplest chord in rock music: just a root and a perfect 5th, sometimes with the root doubled an octave higher. It is written with a 5 after the root, as in C5, E5 or A5, and it contains no 3rd at all. That missing 3rd is the whole point. Without a 3rd the chord cannot be major or minor, so it sounds strong, neutral and open, and it works over almost any harmony, which is why distorted electric guitars rely on it: a full triad through heavy distortion sounds muddy, but a power chord stays clear and punchy. Power chords are also the easiest chords to move around the fretboard, because the shape is the same everywhere. The root sits on the low E or A string, the 5th sits one string up and two frets higher, and the octave sits two strings up and two frets higher. Slide that shape to any fret and you have a new power chord, which is why beginners can play the harmony of a whole rock song after learning a single shape. The simplicity is deceptive, though: good power-chord playing is about muting, timing and dynamics, not about the notes.
How power chords are built
Take the root, count seven semitones up for the perfect 5th, and optionally add the root an octave higher, twelve semitones up. C5 is C and G, with an optional C above. E5 is E and B, with an optional E above. A5 is A and E, with an optional A above. G5 is G and D. On guitar the standard shape puts the root on the 6th or 5th string, the 5th on the next string two frets higher, and the octave two strings higher and two frets higher than the root. The E5 guitar chord is the simplest of all, because the open low E string is the root and the 5th, B, is on the 2nd fret of the A string. Because there is no 3rd, a power chord can stand in for a major or a minor chord without clashing. Over a C major progression, C5 works; over a C minor progression, C5 also works, because the note that would decide the quality is absent. That neutrality is also why power chords are sometimes called neutral chords, and why they are the default choice in punk, metal and hard rock, where the bass and the vocals carry the harmony and the guitar provides the weight. The C5 guitar chord and the A5 guitar chord show the two most common shapes, and the fretboard note finder helps you find any root on the neck.
Worked example — G5. G is the root, and seven semitones above G is D, the perfect 5th, so G5 is G and D, with an optional G an octave above. On guitar, play the 3rd fret of the low E string (G) with your index finger, the 5th fret of the A string (D) with your ring finger, and the 5th fret of the D string (G) with your pinky. That is the G5 guitar chord. Move the whole shape up two frets and you have A5; up two more and you have B5. The chord finder builds any power chord from any root.
How to practise power chords
Power-chord practice is mostly about clean muting and confident movement. The notes are easy; the control is the skill.
- Play E5, A5, D5 and G5 in turn, muting the strings you are not playing with the underside of your index finger.
- Practise the classic movement E5 to G5 to A5, sliding the same shape up the neck and landing cleanly on each fret.
- Play a power chord, lift your fretting fingers slightly to mute it, then play it again, building a tight, rhythmic chugging pattern.
- Play the I–IV–V progression in E major using only power chords: E5, A5 and B5, and keep the timing steady with a metronome.
- Use the metronome at 80 beats per minute and change power chords exactly on the beat, one bar per chord.
Common mistakes
- Letting open strings ring — A power chord uses only two or three strings, and every other string must be muted. Open strings ringing behind a power chord sound messy, especially with distortion, so mute with both hands.
- Pressing too hard — Power chords need far less pressure than barre chords. Squeezing hard slows you down and tires your hand, so use just enough pressure for a clean note and no more.
- Playing the full triad with distortion — A major or minor triad through heavy distortion produces harsh overtones that fight each other. That is exactly why power chords exist: two notes stay clear where three notes turn to mud.
Quick reference
For example, the power chord chord on C is C – G, and every other row follows the same pattern. Use this table as a quick reference when you are building power chord chords away from your instrument. Each row shows the chord on a different root, with the notes spelled in the sharp-only system used across ChordFlow, so you can check the root and perfect 5th pattern at a glance and then find the shape on your own instrument.
| Root | Power Chord notes |
|---|---|
| C | C – G |
| G | G – D |
| D | D – A |
| A | A – E |
| E | E – B |
| F | F – C |
Work through the table one row at a time on your instrument, playing each chord and naming its notes aloud before you move on. When you can build the power chord chord on any of these roots without looking, try the same pattern on the roots that are missing, such as B and F#, and check your answers with the chord finder.
Frequently asked questions
What notes are in a power chord?
The root and the perfect 5th, seven semitones above the root, usually with the root doubled an octave higher. C5 is C and G, plus an optional C above. There is no 3rd, so a power chord is neither major nor minor.
Why are power chords so popular in rock?
Because they sound strong and clear through distortion, where full triads turn muddy, and because the same shape works anywhere on the neck. They are also neutral, so they fit over major and minor harmony alike.
Can I play power chords on an acoustic guitar?
Yes, and they sound good, though they are less essential there, because an acoustic guitar does not distort. On acoustic, full triads usually sound better, but power chords are still useful for driving rhythms.
Is a power chord a real chord?
Strictly speaking, a chord needs three notes, so a power chord is technically an interval, not a chord. In practice everyone calls it a chord, and it functions as one, so the distinction is academic rather than musical.
How do I mute the strings I am not playing?
Rest the underside of your fretting index finger lightly across the strings above the root, and rest the edge of your picking hand on the strings below it. Both hands share the muting job, and the habit becomes automatic with practice.
