E Diminished — Frequently Asked Questions
What notes are in the E Diminished chord?
The E Diminished chord contains: E (root), G (minor third), and Bb (diminished fifth). Both intervals are compressed: the minor third is 3 semitones above the root, and the diminished fifth is 6 semitones — a tritone.
How does E Diminished differ from E Minor?
E Minor has a perfect fifth. E Diminished lowers the fifth by one semitone to Bb (diminished fifth). That extra compression creates intense harmonic tension — the tritone between root and diminished fifth is the most dissonant interval in Western music.
What is the symbol for the E Diminished?
E Diminished is written as Edim or E°. The ° or "dim" symbol means both the third and fifth are minor/diminished. Do not confuse with Edim7 or Eø (half-diminished), which include additional notes.
What are the inversions of E Diminished?
First inversion (E Diminished/G): G–Bb–E. Second inversion (E Diminished/Bb): Bb–E–G. Diminished triads are used in classical music as the vii° chord — the chord one semitone below the tonic, with strong resolution pull.
How is E Diminished used in music?
E Diminished most commonly functions as the vii° chord in a major key, creating strong resolution back to the tonic. It also works as a chromatic passing chord between two nearby chords, and in classical music as a brief point of dissonance. Jazz uses the full four-note dim7 more often than the triad.
What songs use diminished chords?
Michelle (Beatles) uses a diminished chord as a chromatic passing chord. Many classical pieces use vii°–I cadences. Jazz standards use dim7 chords as chromatic passing and approach chords. Diminished harmony also appears in flamenco and film music for dramatic tension.
Practice Tips
- Compare E Minor and E Diminished: only the fifth changes (Bb vs perfect fifth). Play both back to back — the extra compression is striking.
- The tritone between E and Bb creates maximum tension — practice just this two-note interval to hear its characteristic sound.
- E Diminished most naturally resolves up by half step: play Edim then a chord whose root is E raised by one semitone.
- Practice all inversions: E–G–Bb, G–Bb–E, Bb–E–G.
- Use E Diminished as a vii° chord: it is one semitone below E# Major — try Edim → E# Major to feel this powerful classical resolution.
- In a major key, find where E Diminished fits naturally as a passing chord between two diatonic chords a step apart.
