For example, in the key of C major, the chord of G 7 is followed by a chord of C. In order to execute a tritone substitution, a common variant of this progression, one would replace the dominant seventh chord with a dominant chord that has its root a tritone away from the original: Three kinds of perfect cadence
The diminished triad can be used to substitute for the dominant seventh chord. In major scales, a diminished triad occurs only on the seventh scale degree. For instance, in the key of C, this is a B diminished triad (B, D, F). Since the triad is built on the seventh scale degree, it is also called the leading-tone triad.
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 primary difference between these two scales is the seventh degree, with the double harmonic majorb7 scale having a flat seventh (♭7) and the Double Harmonic Major having a natural seventh (7). The scale contains a built-in tritone substitution, a dominant seventh chord a half step above the root, with strong harmonic movement towards the ...
the fifth note the V major chord (or even a dominant 7th), the sixth note the vi minor chord, the seventh note the vii diminished chord and; the octave would be a I major chord. Using the minor (aeolian mode) one would have: i minor, ii diminished, (♭)III major, iv minor, v minor, (♭)VI major, (♭)VII major and; the i minor an octave ...
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 ...
Dominant seventh chord normally paired with mixolydian scale, [5] the fifth mode of the major scale. The scales commonly used today consist of the seven modes of the diatonic scale, the seven modes of the melodic minor scale, the diminished scales, the whole-tone scale, and pentatonic and bebop scales.

When we arrange the notes of the C major scale in ascending pitch and use only these notes to build a seventh chord, and we start with G (not C), then the resulting chord contains the four notes G–B–D–F and is called G dominant seventh (G 7). The note F is a minor seventh from G, and is also called the dominant seventh with respect to G.
