In music, a minor seventh chord is a seventh chord composed of a root note, a minor third, a perfect fifth, and a minor seventh (1, ♭ 3, 5, ♭ 7). In other words, one could think of it as a minor triad with a minor seventh attached to it. [2] For example, the minor seventh chord built on A, commonly written as A− 7, has pitches A-C-E-G:
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 function. The major seventh plays the tonic (I7) and subdominant (IV 7) roles; The minor seventh plays the ii 7, iii 7, and vi 7 roles.
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 ...
In major keys, the chords iii and vi are often substituted for the I chord, to add interest. In the key of C major, the I major 7 chord is "C, E, G, B," the iii chord ("III–7" [11]) is E minor 7 ("E, G, B, D") and the vi minor 7 chord is A minor 7 ("A, C, E, G"). Both of the tonic substitute chords use notes from the tonic chord, which means ...
For example, the relative minor of C major is A minor, and in the key of A minor, the i, iv and v chords are A minor, D minor and E minor. In practice, in a minor key, the third of the dominant chord is often raised by one semitone to form a major chord (or a dominant seventh chord if the seventh is added).
A ninth chord includes the seventh; without the seventh, the chord is not an extended chord but an added tone chord—in this case, an add 9. Ninths can be added to any chord but are most commonly seen with major, minor, and dominant seventh chords. The most commonly omitted note for a voicing is the perfect fifth.
