The chord consists of a diminished triad plus the diminished seventh above the root. These four notes form a stack of three intervals which are all minor thirds.Since stacking yet another minor third returns to the root note, the four inversions of a diminished seventh chord are symmetrical.
The leading-tone diminished triad and supertonic diminished triad are usually found in first inversion (vii o 6 and ii o 6, respectively) since the spelling of the chord forms a diminished fifth with the bass. [6] This differs from the fully diminished seventh chord, which commonly occurs in root position. [8]
A diminished seventh chord consists of three superposed minor thirds, and thus has all successive notes a minor third apart; it contains two diminished fifths. In jazz theory, a diminished seventh chord has four available tensions, each a major ninth above the chord tones, and thus forming a diminished seventh chord a whole tone (or major ninth ...
Interval cycles, "unfold [i.e., repeat] a single recurrent interval in a series that closes with a return to the initial pitch class", and are notated by George Perle using the letter "C", for cycle, with an interval-class integer to distinguish the interval. Thus the diminished-seventh chord would be C3 and the augmented triad would be C4.
The diminished triad also contains a tritone in its construction, deriving its name from the diminished-fifth interval (i.e. a tritone). The half-diminished seventh chord contains the same tritone, while the fully diminished seventh chord is made up of two superposed tritones a minor third apart.
When the terms minor, major, augmented, diminished, or the corresponding symbols do not appear immediately after the root note, or at the beginning of the name or symbol, they should be considered interval qualities, rather than chord qualities. For instance, in Cm M7 (minor major seventh chord), m is the chord quality and M refers to the interval.

Diminished triads may be represented by lower-case Roman numerals with a degree symbol (e.g., vii o 7 indicates a diminished seventh chord built on the seventh scale degree; in the key of C major, this chord would be B diminished seventh, which consists of the notes B, D, F and A ♭).
