Bbdim Chord Piano

The Bbdim chord is made up of three notes – Bb, Db, and Fb.

If you’re new to chords, the ‘dim’ is short for ‘diminished’ and the chord is also referred to as the ‘Bb diminished triad’.

Also, you may be wondering, why the third note is Fb… isn’t that just an E? Well, it’s to do with the way chords are constructed. I’ll save that theory for another time, but feel free to think of the Fb as an E instead.

Moving on…

You can actually play a Bbdim chord on piano in three ways:

  • Root Position – This is where the Bb note is the lowest note of the chord
  • First Inversion – This is where the Db note is the lowest note of the chord
  • Second Inversion – This is where the Fb note is the lowest note of the chord

I’ll quickly explain this in some more detail, with images and audio clips below.


Bbdim Chord Piano – Root Position

Whenever you play a Bbdim chord on piano, and Bb is the lowest note, that’s known as root position. It looks like this:

There are seven places on a standard piano where you can play a Bbdim chord in root position. If you have a piano close by, try playing each one.

Below you’ll see what all seven look like on sheet music. Click the play button if you’d like to hear what they sound like too.
