What the Bmaj7 chord sounds like

The major seventh chord sounds soft, dreamy and a little jazzy. The major seventh sits a half step below the root, so it rubs gently against it without needing to resolve.

1	B	root

5	F♯	perfect fifth (7 semitones) – often omitted on fretted instruments

How to play it – with fingering

Easy version

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

A shape, fret 2, barre at fret 2

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

For the barre, lay your index finger flat across all the marked strings at fret 2; your other fingers press the higher frets.

Position 6

String 1 (e): fret 6, index finger (A♯4)
String 2 (B): fret 7, middle finger (F♯4)
String 3 (G): fret 8, ring finger (D♯4)
String 4 (D): fret 9, little finger (B3)
String 5 (A): not played
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 Bmaj7 with a capo

A capo clamps all the strings at one fret, so a familiar open shape sounds higher. You can also get a Bmaj7 chord with these open shapes:

Capo: fret 2
shape: Amaj7

Capo: fret 4
shape: Gmaj7

Capo: fret 6
shape: Fmaj7

Capo: fret 7

Frequently asked questions

What notes are in the Bmaj7 chord?

B, D♯, F♯, A♯. The root is B; the intervals of the other notes from the root: major third, perfect fifth, major seventh.

What is the easiest way to play Bmaj7 on guitar?

The easiest shape above is “Easy version”, 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 Amaj7 shape at fret 2 or a Gmaj7 shape at fret 4.

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 is a note missing from some Bmaj7 shapes?

On a fretted instrument you can't always play every note of a 4-note chord. The fifth (F♯) may be dropped – the chord keeps its character without it.

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.
