This triad is consequently called the supertonic diminished triad. Like the supertonic minor triad found in a major key, the supertonic diminished triad has a predominant function, almost always resolving to a dominant functioning chord. [7] If the music is in a minor key, diminished triads can also be found on the raised seventh note, ♯ vii o.
An augmented triad is a chord, made up of two major thirds (an augmented fifth). The term augmented triad arises from an augmented triad being considered a major chord whose top note (fifth) is raised. When using popular-music symbols, it is indicated by the symbol "+" or "aug". For example, the augmented triad built on A ♭, written as A ...
minor triads contain a minor third with a major third stacked above it, e.g., in the minor triad A–C–E (A minor), A–C is a minor third and C–E is a major third. diminished triads contain two minor thirds stacked, e.g., B–D–F (B diminished) augmented triads contain two major thirds stacked, e.g., D–F ♯ –A ♯ (D augmented).
There are four basic triads (major, minor, augmented, diminished). They are all tertian —which means defined by the root, a third, and a fifth . Since most other chords are made by adding one or more notes to these triads, the name and symbol of a chord is often built by just adding an interval number to the name and symbol of a triad.
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 constructed via the tertian harmonization of a major scale. [81] As already stated, The major-minor seventh has the dominant V 7 ...
In a lot of jazz styles, an unembellished major triad is rarely if ever played, but in a lead sheet the choice of which major quality chord to use is left to the performer. + or aug indicates an augmented chord (A or a is not used). o or dim indicates a diminished chord, either a diminished triad or a diminished seventh chord (d is not used).
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.
The diminished triad can be used to substitute for the dominant seventh chord. In major scales, a diminished triad occurs only on the seventh scale degree. For instance, in the key of C, this is a B diminished triad (B, D, F). Since the triad is built on the seventh scale degree, it is also called the leading-tone triad.
