Not including the root motion, there is only a one-note difference between a half-diminished seventh chord and a V 7 chord with a flat ninth. Since it is built on the diatonic II chord of the minor scale, most of the time the II-V pattern resolves to a minor tonic (such as in the progression D ø 7 – G 7 ♭ 9 – Cm), but there are also ...
A half-diminished seventh chord is a seventh chord built from the seventh degree of a major scale. It is considered "half-diminished" because a fully diminished seventh has a double-flatted (diminished) seventh, making it enharmonically the same as a major sixth. The half-diminished seventh chord uses a minor seventh over the root of a ...
Half-diminished seventh chord on C (Play ⓘ). A diminished triad with a minor seventh is a half-diminished chord, usually notated either Cm 7(♭ 5) or C ø7. A diminished triad played over a root a major third away creates a Dominant 7th chord, notated C 7, with a C Major triad on the bottom, and an E° from the chord third of C (C E G B ...
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 harmonic minor scale. It typically has dominant function and contains two diminished fifths, which often resolve ...
This pattern of whole and half steps characterizes the natural minor scales. The intervals between the notes of a natural minor scale follow the sequence below: whole, half, whole, whole, half, whole, whole. where "whole" stands for a whole tone (a red u-shaped curve in the figure), and "half" stands for a semitone (a red angled line in the ...
In short, lowering any note of a diminished seventh chord by a half tone leads to a dominant seventh chord (or German sixth enharmonically), the lowered note being the root of the new chord. Raising any note of a diminished seventh chord by a half tone leads to a half-diminished seventh chord, the root of which is a whole step above the raised ...
The leading-tone seventh chords are vii ø 7 and vii o 7, [24] the half-diminished and diminished seventh chords on the seventh scale degree of the major and harmonic minor. For example, in C major and C minor, the leading-tone seventh chords are B half-diminished (B–D–F–A) and B diminished (B–D–F–A ♭), respectively.
A major interval is one semitone larger than a minor interval. The words perfect, diminished, and augmented are also used to describe the quality of an interval.Only the intervals of a second, third, sixth, and seventh (and the compound intervals based on them) may be major or minor (or, rarely, diminished or augmented).
