What are Power chords? Power chords are a type of musical chord commonly used in rock, punk, and other forms of popular music. They are simple yet powerful chords that consist of only two notes, typically the root note and the fifth note of a given musical scale. Power chords are characterised by their strong and stable sound, making them a fundamental element in many rock and metal guitar riffs and songs.

Here are the key components of a power chord:

Root Note

The primary or fundamental note upon which a chord or scale is built. It is the starting point and serves as the foundation for the musical structure. The root note determines a chord or scale’s name and tonal characteristics.

In a chord:

The root note is the note from which the other notes in the chord are derived. It defines the chord’s name and tonality. For example, in a C major chord (C-E-G), the root note is C.

In a scale:

The root note is the first note of the scale and the reference point for all other notes in the scale. For example, in a C major scale (C-D-E-F-G-A-B), the root note is C.

Fifth Note

The fifth note of the scale is added to the root note to create the power chord. This note is usually played one octave higher than the root note, which gives the chord its distinctive sound. In terms of music theory, this interval is called a perfect fifth.

In a major scale, for example, the fifth note is found by counting up five scale degrees from the root note. In the key of C major, which consists of the notes C-D-E-F-G-A-B-C, the fifth note is G, as it is five steps up from C.

Absence of a Third

Unlike traditional major or minor chords, power chords do not include the third note of the scale. This omission of the third note (determining whether a chord is major or minor) gives power chords their ambiguous and versatile quality. They can be used in various musical contexts without sounding overly major or minor.

Power chords are often played on the guitar and are relatively easy to play because they involve just two or three fingers on the fretboard. Typically, they are played using only the root note and the fifth note on adjacent strings, and sometimes, an optional octave note is added for extra depth and power.

Here’s a common fingering for an A power chord on the guitar:

Place your index finger on the 5th fret of the low E string (the A note).

Place your ring finger on the 7th fret of the A string (the E note).

You can also optionally add your pinky to the 7th fret of the D string (another A note).

By using this basic formula and moving it up and down the neck of the guitar, you can play power chords based on different root notes, allowing you to create the powerful, distorted, and driving sounds often associated with rock music. Power chords are frequently combined with distortion or overdrive effects to enhance their sound further.


Power chords are fundamental in many forms of rock, punk, and popular music. They are simple yet powerful chords composed of just two notes: the root and the fifth notes of a musical scale. These chords are characterised by their strong and stable sound, making them a staple in guitar-driven music.

Power chords are versatile and adaptable because they lack the third note in major and minor chords, giving them an ambiguous tonality. Guitarists often use power chords in combination with distortion or overdrive effects to create the signature gritty and aggressive sound associated with rock music.

Understanding the concept of root notes and fifth notes is crucial when working with power chords, as the root note determines the chord’s name and tonal centre, while the fifth note adds depth and strength to the sound. Power chords are a valuable tool for musicians seeking to create energetic and impactful music.
