About the chord

E diminished guitar chord

Eo is the E diminished guitar chord. It uses the notes E, G, and B♭ and the interval formula 1-♭3-♭5.

The E diminished diminished chord is built from minor thirds, including a diminished fifth B♭, producing a tense, unstable sound. This dissonant, unresolved tension is commonly used for dramatic transitions, suspenseful moments, or eerie atmospheres in classical, jazz, and film music.

Also written as Edim and Em♭5.
