What the B5 chord sounds like

A power chord has only the root and the fifth, no third, so it is neither major nor minor. With a distorted guitar it sounds the cleanest – the backbone of rock and metal.

How to play it – with fingering

Open position

String 1 (e): fret 2, index finger (F♯4)
String 2 (B): open (B3)
String 3 (G): not played
String 4 (D): not played
String 5 (A): not played
String 6 (E): not played

String 2 (B): open (B3)
String 3 (G): fret 4, ring finger (B3)
String 4 (D): not played
String 5 (A): not played
String 6 (E): not played

A shape, fret 2

String 1 (e): not played
String 2 (B): not played
String 3 (G): fret 4, little finger (B3)
String 4 (D): fret 4, ring finger (F♯3)
String 5 (A): fret 2, index finger (B2)
String 6 (E): not played

The “C, A, G, E and D shapes” are the CAGED system: you slide the shape of the open C, A, G, E or D chord up the neck and your index finger (a barre) takes over the job of the nut. That way the same chord can be played in five places, anywhere on the fretboard.

Tuning: E A D G B E (low to high). String 6 is the thickest, the low E. In the diagram, × means the string is not played, and a circle means an open string.

Playing B5 with a capo

A capo clamps all the strings at one fret, so a familiar open shape sounds higher. You can also get a B5 chord with these open shapes:

Capo: fret 2
shape: A5

Capo: fret 7
shape: E5

Frequently asked questions

What notes are in the B5 chord?

B, F♯. The root is B; the intervals of the other notes from the root: perfect fifth.

What is the easiest way to play B5 on guitar?

The easiest shape above is “Open position”, rated easy. We show 6 shapes, from open and easy versions to movable barre shapes higher up the neck. With a capo you can also play it as a A5 shape at fret 2 or a E5 shape at fret 7.

How do I read the chord diagram?

Strings run from the lowest (left) to the highest (right) – tick “Left-handed” to mirror it. Rows are frets; a number at the side shows the starting fret. Dots are fingers (1 index, 2 middle, 3 ring, 4 little), a long bar is a barre, × means don't play that string and ○ means play it open.

Why do some songbooks write H instead of B?

In German and Central European notation, H is the note B, and B is the note B♭. So a “B” chord in a German or Hungarian songbook is B♭ in English notation, and an “H” chord is B. Always check which notation your chord chart uses.
