the chord quality (e.g. minor or lowercase m, or the symbols o or + for diminished and augmented chords, respectively; chord quality is usually omitted for major chords) whether the chord is a triad, seventh chord, or an extended chord (e.g. Δ 7) any altered notes (e.g. sharp five, or ♯ 5) any added tones (e.g. add2)
The diminished seventh chord is a four-note chord (a seventh chord) composed of a root note, together with a minor third, a diminished fifth, and a diminished seventh above the root: (1, ♭ 3, ♭ 5, 7). For example, the diminished seventh chord built on B, commonly written as B o 7, has pitches B-D-F-A ♭:
In dominant function, the VII half diminished chord, like its fully diminished counterpart, can take the place of the dominant V chord at a point of cadential motion. This chord, sometimes called a leading-tone diminished seventh chord , is represented by the Roman numeral notation vii ø 7 , the root of which is the leading-tone to the tonic ...
a diminished seventh chord (vii o 7), which is generated by minor thirds; Because they are generated by just one interval, the inversions of augmented triads and diminished seventh chords introduce no new intervals (allowing for enharmonic equivalents) that are absent from its root position.
The half-diminished seventh concatenates a diminished triad with a major third, supplementing it with a diminished-seventh interval. The (fully) diminished seventh concatenates a diminished triad with a minor third, supplementing it with a diminished-seventh interval. [80] Four of these five seventh-chords—all but the diminished seventh—are ...
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.
However, in most popular-music chord books, the symbol "dim" or "o" represents a diminished seventh chord (a four-tone chord), which in some modern jazz books and music theory books is represented by the "dim7" or "o 7" symbols. For example, the diminished triad built on B, written as B o, has pitches B-D-F:
The augmented chord on I may contain the major seventh (I 7 5 (Play ⓘ) or I 6 5 (Play ⓘ)), while the augmented chord on V may contain the minor seventh (V 7 5 (Play ⓘ), V 6 5 (Play ⓘ), or V 4 3 (Play ⓘ)). [1] In C: C–E–G ♯ –B and G–B–D ♯ –F. The augmented triad on the V may be used as a substitute dominant, and may ...
