In music theory, a diminished triad is a triad consisting of two minor thirds above the root. [3] It is a minor triad with a lowered fifth. When ...
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 ...
In classical music from Western culture, a diminished third (Play ⓘ) is the musical interval produced by narrowing a minor third by a chromatic semitone. [ 1 ] [ 4 ] For instance, the interval from A to C is a minor third, three semitones wide, and both the intervals from A ♯ to C, and from A to C ♭ are diminished thirds, two semitones wide.
In most genres of popular music, including jazz, pop, and rock, a chord name and its corresponding symbol typically indicate one or more of the following: the root note (e.g. C ♯) 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 ...
The chord notation for the diminished seventh chord (assuming root C) is Cdim 7 or C o 7 (or Cm 6 ♭ 5 for the enharmonic variant). The notation Cdim or C o normally denotes a (three-note) diminished triad, but some jazz charts or other music literature may intend for these to denote the four-note diminished seventh chord instead.
In music theory, a diminished major seventh chord is a seventh chord composed of a diminished triad and a major seventh. [1] Thus, it is composed of a root note, together with a minor third, a diminished fifth, and a major seventh above the root: (1, ♭ 3, ♭ 5, 7).
The diminished fifth is often called a tritone in modern tonal theory, but functionally and notationally it can only resolve inwards as a diminished fifth and is therefore not reckoned a tritone—that is, an interval composed of three adjacent whole tones—in mid-renaissance (early 16th-century) music theory. [19]
In modern Western tonal music theory, a diminished second is the interval produced by narrowing a minor second by one chromatic semitone. [1] In twelve-tone equal temperament, it is enharmonically equivalent to a perfect unison; [3] therefore, it is the interval between notes on two adjacent staff positions, or having adjacent note letters, altered in such a way that they have no pitch ...
