The B augmented chord (B+) is a B Major chord, with a raised 5th. It contains the notes B, D# and Fx (F double sharp).

The note ‘F double sharp’ (Fx) is actually enharmonically the same as G, but the because the augmented chord contains a raised 5th, it is better to refer to this notes as F double sharp, in order to correctly indicate that it is an F sharp that has been augmented (raised by one semitone).

Each note of the B augmented chord is separated by an interval of a Major 3rd. Because every interval inside the B augmented chord is identical, it is known as a symmetrical chord. Another way of looking at this is as follows – If you play an augmented chord starting from any of the notes inside the B+ chord, the new chord will contain the same notes as the B augmented chord:

  • The B augmented chord contains the notes B, D#, Fx
  • The D# augmented chord contains the notes D#, Fx, Ax (that’s A double sharp, which is the same as B)
  • The Fx augmented chord contains the notes Fx, B, D#

Some Quick B+ Chord Theory

  • The B augmented chord contains the notes B, D# and Fx.
  • The B+ chord is produced by playing the 1st (root), 3rd and sharp 5th note of the B Major scale.
  • The B augmented chord (just like all augmented chords) contains the following intervals (from the root note): Major 3rd, Major 3rd, Major 3rd (back to the root note).
  • B augmented is an B chord, with the F# raised to Fx.
  • The B augmented chord resolves naturally to the E minor or E Major chord.
