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:
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 ...
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.
Magic chord (as played in The Well-Tuned Piano). [ 3 ] The Magic Chord is a chord and installation (1984) created by La Monte Young , consisting of the pitches E, F, A, B ♭ , D, E, G, and A, in ascending order and used in works including his The Well-Tuned Piano and Chronos Kristalla (1990). [ 1 ]
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 ...
More tunings of the minor chord are also available in various equal temperaments other than 12-TET. Rather than directly from the harmonic series, Sorge derived the minor chord from joining two major triads; for example the A minor triad being the confluence of the F and C major triads. [13] A–C–E = F–A–C–E–G. Given justly tuned ...
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.
