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 term scale step is sometimes used synonymously with scale degree, but it may alternatively refer to the distance between two successive and adjacent scale degrees (see steps and skips). The terms " whole step " and " half step " are commonly used as interval names (though "whole scale step" or "half scale step" are not used).
Put another way, it is the key whose tonic is the dominant scale degree in the main key. [8] If, for example, a piece is written in the key of C major, then the tonic key is C major and the dominant key is G major since G is the dominant note in C major. [9] "Essentially, there are two harmonic directions: toward I and toward V.
The pattern of whole and half steps characteristic of a major scale. The intervals from the tonic (keynote) in an upward direction to the second, to the third, to the sixth, and to the seventh scale degrees of a major scale are called major. [1] A major scale is a diatonic scale. The sequence of intervals between the notes of a major scale is:
Of the seven notes in the major scale, a seventh chord uses only four (the root, third, fifth, and seventh). The other three notes (the second, fourth, and sixth) can be added in any combination; however, just as with the triads and seventh chords, notes are most commonly stacked – a seventh implies that there is a fifth and a third and a root.
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.

[citation needed] From that, we can list the scales and the triad qualities and the seventh chord qualities in each scale as degrees of Dorian mode and Aeolian dominant scale (Dorian ♯3 ♭6 scale) and Neapolitan major scale (Dorian ♭2 ♯7 scale) and double harmonic scale (Dorian ♭2 ♯3 ♭6 ♯7 scale) and the two types of Dorian ...
