How to use the E Diminished chord

The E Diminished chord is built from a root, a minor third and a diminished fifth. Start at the root E and stack the intervals to get the whole chord: E, G and B♭. The same formula gives you the chord in any other key.

Diminished chords are passing tools in classical, jazz, bluegrass and film music. They're often used as vii° leading to the tonic or as chromatic passing chords between diatonic chords.

In major keys E° is the vii° in F major; in minor keys it's the ii° in D minor.

How E Diminished differs from similar chords

E° is Em with the fifth lowered by a half step, and that flat fifth is the whole difference. Add a minor seventh and you get Em7♭5, add a diminished seventh and you get the fully symmetrical E°7. On its own it is the leading-tone chord (vii°) of the major key a half step up.

Where E Diminished is used

A diminished chord is a tension chord. It works as the leading-tone chord of a key, and as a dominant seventh with its root left out.

As the leading-tone chordF major
  1. vii°E°
  2. IF

Every note pulls inward into F by a semitone or a tone. This is the chord's primary function.

As the ii in a minor ii-V-iD minor
  1. ii°E°
  2. V7A7
  3. iDm

The minor cadence. E Diminished leads into the dominant, and the seventh is what makes it a ii rather than a diminished triad.
