Dominant seventh chords are often built on the fifth scale degree (or dominant) of a key. For instance, in the C major scale, G is the fifth note of the scale, and the seventh chord built on G is the dominant seventh chord, G 7 (shown above). In this chord, F is a minor seventh above G.
The most common chords are tertian, constructed using a sequence of major thirds (spanning 4 semitones) and/or minor thirds (3 semitones). Since there are 3 third intervals in a seventh chord (4 notes) and each can be major or minor, there are 7 possible permutations (the 8th one, consisted of four major thirds, results in a non-seventh augmented chord, since a major third equally divides the ...
Minor major seventh chord. A minor major seventh chord, or minor/major seventh chord (also known as the Hitchcock Chord) is a seventh chord composed of a root, minor third, perfect fifth, and major seventh (1, ♭ 3, 5, and 7). It can be viewed as a minor triad with an additional major seventh.
However, in a minor key, the seventh scale degree is often raised by a half step (♭ to ♮), creating a major chord. These chords may also appear as seventh chords: typically as a dominant seventh chord, but occasionally in minor as a minor seventh chord v 7 with passing function: [6]
For example, the seventh of the dominant seventh chord, resolving to tonic, moves downward to the third of the following chord. In the key of C major, the dominant seventh chord would be G 7; the seventh note of this G 7 chord is F, which should resolve downwards to an E in the next bar (typically supported by a C-major chord).
This chord progression instructs the performer to play, in sequence, a C major triad, an A minor chord, a D minor chord, and a G dominant seventh chord. In a jazz context, players have the freedom to add sevenths, ninths, and higher extensions to the chord. In some pop, rock and folk genres, triads are generally performed unless specified in ...
A seventh chord with a minor third, perfect fifth, and minor seventh is commonly called a minor seventh chord, but also sometimes a minor/minor seventh chord to distinguish it from the minor/major seventh chord discussed below. It can be represented as either as m 7 or − 7, or in integer notation, {0, 3, 7, 10}.
The major seventh spans eleven. For example, the interval from A 3 to G 4 is a minor seventh, ... producing the all-important dominant seventh chord.
