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

Each note of the B flat 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 Bb+ chord, the new chord will contain the same notes as the B flat augmented chord:

  • The Bb augmented chord contains the notes Bb, D, F#
  • The D augmented chord contains the notes D, F#, A# (same as Bb)
  • The F# augmented chord contains the notes F#, A#, Cx (that’s C double sharp, the same as D)
