ABSTRACT
Fully-diminished seventh chords occur in only one place in the entire tonal system: as the leading tone seventh chord in the minor mode:
Use this as your point of reference. Fully-diminished seventh chords are symmetrical-all of the intervals are the same (when inverted, the second is an
augmented second which is enharmonically the same as a minor third). As a result, it is not possible to determine the inversion when taken out of context.
