View source for 7th Chords

''Seventh Chords'' extend our basic Root-3rd-5th triad chords by adding a 7th (R-3-5-7).  This extra note adds an additional degree of harmonic complexity to chords.  They can be used to strenghthen or weaken the resolve of cadences, as well as simply making things more interesting.  It gives us a much greater variety of chords to choose from.

== Diatonic Chords ==
Only Dominant 7ths, Minor 7ths, Major 7ths, and Half-Diminished 7ths are diatonic to the major and natural minor scales.

Harmonic Minor uses those but additionally adds an Augmented 7th, a Minor/Major 7th, and a Fully Diminished 7th.  Every chord is a unique variation.

The Fully Diminished 7th is also diatonic to the octatonic diminished scales (Whole-Half and Half-Whole).
