Why it sounds like that

B major is built from the formula 1, 3, 5, with the major third D♯ giving it its bright quality. Compare it to B minor, which lowers the third to D.

What goes wrong with B major?

  • Letting the low E string sound through, which is outside the chord.
  • Pressing the barre too flat and deadening the high e string.

When to use it

B major is the tonic in B major, so it anchors progressions like B–E–F♯, the I–IV–V. It also appears in E major and F♯ major keys. Use it for rock, metal, and pop.

Changing to and from B major

  • Sliding the shape down one fret to the 1st fret gives B♭ major.
  • From B major to E major, move the barre to the 7th fret and adjust the other fingers to the E shape.

Which voicing to use

The 2nd fret barre shape is the standard, but the B/D♯ inversion with D♯ in the bass offers a different sound. The 7th fret barre shape gives a higher voicing.

What is the difference between B major and B minor?
