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).
The harmonic seventh chord is a dominant seventh chord formed by a major triad plus a harmonic seventh interval. The harmonic seventh interval is a minor seventh tuned in the 7:4 pitch ratio, one of the possible "just ratios" defined for this interval in just intonation (slightly below the width of a minor seventh as tuned in equal temperament ...
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.
For example, the seventh of the dominant seventh chord, resolving to tonic, moves downward to the third of the following chord. In the key of C major, the dominant seventh chord would be G 7; the seventh note of this G 7 chord is F, which should resolve downwards to an E in the next bar (typically supported by a C-major chord).
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 ...
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.
A leading-tone triad is a triad built on the seventh scale degree in a major key (vii o in Roman numeral analysis), while a leading-tone seventh chord is a seventh chord built on the seventh scale degree (vii ø 7). Walter Piston considers and notates vii o as V 0 7, an incomplete dominant seventh chord. [1]
However, in practice, many songs in E minor will use IV (A major), which is borrowed from the key of E major. Borrowing from the parallel major in a minor key, however, is much less common. Using the V7 or V chord (V dominant 7, or V major) is typical of most jazz and pop music regardless of whether the key is major or minor.
