E Flat Diminished Chord on Piano (Ebdim)

E flat diminished (Ebdim) is spelled Eb - Gb - Bbb: root, minor 3rd and diminished 5th. Its sound is tense, so it rarely stays long before moving on. Here is where Ebdim comes from, where it resolves and how to play it with both hands.

What Ebdim does in music

  • Ebdim is the vii° chord of E major (as D#dim) and the ii° chord of C# minor (as D#dim).
  • It wants to move up a semitone: Ebdim (D#dim) → E / Em, the bottom note rising to the new root.
  • Add Db and you get Ebm7b5 (half-diminished); add Dbb instead and you get Ebdim7 (diminished 7th).
