Diminished Seventh Chord
The diminished seventh chord is a four-note chord (a seventh chord) composed of a Root (chord), 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 Chord names and symbols (popular music), written as B7, has pitches B-D-F-A: : The chord consists of a diminished triad plus the diminished seventh above the root. These four notes form a stack of three Interval (music), intervals which are all minor thirds. Since stacking yet another minor third returns to the root note, the four Inversion (music), inversions of a diminished seventh chord are symmetrical. The Pitch class#Integer notation, integer notation is . Since the diminished seventh interval is enharmonically equivalent to a major sixth, the chord is enharmonically equivalent to (1, 3, 5, 6). The diminished seventh chord occurs as a leading-tone seventh chord in the harm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Diminished Triad
In music theory, a diminished triad is a triad (music), triad consisting of two minor thirds above the root (chord), root. It is a Minor chord, minor triad with a lowered (flat (music), flattened) Fifth (chord), fifth. When using Chord names and symbols (popular music), chord symbols, it may be indicated by the symbols "dim", "", "m5", or "MI(5)". However, in most popular-music chord books, the symbol "dim" or "" 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 "7" symbols. For example, the diminished triad built on B, written as B, has pitches B-D-F: : The chord can be represented by the Pitch class#Integer notation, integer notation . In the common practice period, the diminished triad is considered Consonance and dissonance, dissonant because of the Tritone, diminished fifth (or tritone).
