In music theory, a dominant seventh chord, or major minor seventh chord, [a] is a seventh chord composed of a root, major third, perfect fifth, and minor seventh; thus it is a major triad together with a minor seventh. It is often denoted by the letter name of the chord root and a superscript "7". [3]
In music, a major seventh chord is a seventh chord in which the third is a major third above the root and the seventh is a major seventh above the root. The major seventh chord, sometimes also called a Delta chord, can be written as maj 7, M 7, Δ, ⑦, etc. The "7" does not have to be superscripted, but if it is, then any alterations, added ...

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 ...
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.
In a major key, the supertonic triad (ii) is minor, and in a minor key it is diminished. The dominant is, in its normal form, a major triad and commonly a dominant seventh chord. With the addition of chord alterations, substitutions, and extensions, limitless variations exist on this simple formula.
Simulates the top four strings, followed by the second-from-bottom string on top, raised a whole step (the F ♯ representing both the top and bottom E). It makes playing in the key of A major easier, though chord fingerings have to be altered unless the strings are rearranged to F ♯-B-E-A-C ♯. Open G tuning – G-d-g-b-d'
In jazz, the altered scale, altered dominant scale, or super-Locrian scale (Locrian ♭ 4 scale) is a seven-note scale that is a dominant scale where all non-essential tones have been altered. This means that it comprises the three irreducibly essential tones that define a dominant seventh chord , which are root, major third, and minor seventh ...
