Why it sounds like that

B 6th is built from the formula 1, 3, 5, 6. The major sixth G♯ added to the B major triad gives the chord a bright, singing quality. Compare it with B major, which lacks the sixth.

What goes wrong with B 6th?

  • Letting the low E string ring: mute it with the thumb, or the open E clashes with the chord.
  • Flattening the pinky onto the B string and deadening the open string.
  • Not pressing the D and G strings hard enough, causing a buzz.

When to use it

B 6th is the tonic in B major, used in the I–IV–V–I progression B–E–F♯–B. Its open B string gives a ringing quality that suits rock and pop. Use it to brighten a B major chord in a chorus.

Changing to and from B 6th

  • Sliding the shape up one fret to the 2nd fret gives C 6th; the open B string becomes fretted, so the hand must adjust.

Which voicing to use

The open shape keeps the root B in the bass and is the easiest to play. The B6/D♯ inversion at the 1st fret places the third in the bass, which makes the chord sound more delicate.

Common questions

How does B 6th differ from B major 7th?

B 6th adds the sixth G♯, while B major 7th adds the seventh A♯. The sixth gives a warmer, less tense sound than the seventh.

Can I play B 6th with a barre at the 6th fret?

Yes, the 6th fret shape is a full barre with the root on the A string. It is easier to move up the neck than the open shape.

Why is the low E string muted?

The low E is not a chord tone, so it must be muted to keep the bass note on B and avoid a muddy sound.
