Why it sounds like that

What goes wrong with E diminished 7th?

  • Letting the index finger mute the C string by lying flat.
  • Pressing the pinky on the A string fret 10 without enough arch, deadening the E string.
  • Strumming before all four fingers are firmly placed.

When to use it

E diminished 7th works as a passing chord between E minor 7th flat 5th and F♯ minor. Its tense, symmetrical sound suits jazz turnarounds and dramatic pauses in ballads.

Changing to and from E diminished 7th

  • Sliding the shape down one fret to the 8th fret gives E♭ diminished 7th.
  • Sliding the shape up one fret to the 10th fret gives F diminished 7th.

Which voicing to use

The 9th fret voicing puts E in the bass, giving the most direct root-position sound. The Edim7/G inversion at the open position places G in the bass, which softens the chord's attack and works well when moving to an F♯ chord.
