The '''fully diminished seventh chord''' is quite rare for diatonic chord progressions; however, it is very handy for [[Modulation|modulating ]] between keys. It serves as a pivot chord between basically any 2 keys. It is also useful to enter an atonal feel, where chromatic or octatonic scales can play over the chord. It is the diatonic vii{{dim}}{{7}} of harmonic minor.

{{top}} == Diatonic Chords =={{Crumbs|blue|3|7th Chords#Varieties of 7th Chords|Varieties|7th Chords#Common Open Position Voicings|Open Pos. Voicings|7th Chords#Diatonic Chords|Diatonic Chords|7th Chords#Why/When 7ths?|Why/When 7ths?}}
Only dominant 7ths, minor 7ths, major 7ths, and half diminished 7ths are diatonic to the major and natural minor scales.
The fully diminished 7th is also diatonic to the [[Exotic Scales|octatonic diminished scales (Whole-Half and Half-Whole)]].
=== Sample Progressions === {{top}} == Why/When 7ths? =={{Crumbs|blue|4|7th Chords#Varieties of 7th Chords|Varieties|7th Chords#Common Open Position Voicings|Open Pos. Voicings|7th Chords#Diatonic Chords|Diatonic Chords|7th Chords#Why/When 7ths?|Why/When 7ths?}}
In general, 7ths can be used to get a more complex sound than a basic triad. Added on top of major/minor triads typically makes them feel less resolved. This is particularly handy for the Dominant 7th, as the dominant (V) chord is generally desired to feel tense, seeking resolution to the tonic (I or i). Adding a 7th to the tonic triad weakens its sense of resolution; however, it still serves as tonic and is the guiding beacon for the harmony. The tonic 7th can give a feeling of incomplete resolution, making the music feel more relaxed and flowing than seeking completion.
''The most common use of 7th chords comes in the form of '' V{{7}} - I (or V{{7}} - i) ''progressions.''
As noted for the augmented 7th and half diminished 7th Chords, the 7th helps add consonance and lightens the feel of the basic triad, while adding a richer harmony to it and making it feel more complex. complExample I recommend always using the half diminished 7th over the triad when diatonic to the current key, especially as the vii{{hdim}}{{7}} chord of a major key.
Sevenths can also be desirable for voice leading purposes. Or it may simply be implied by a melody line.
Fully diminished and minor/major 7th chords are particularly dissonant and create a particularly unresolved feeling. The fully diminished 7th chord can also be used to signal an atonal feel.

Get a feel for when 7th chords are appropriate and when they are not, based on the harmonic function of the chord as well as the style of music.* Create your own progressions, substituting in diatonic 7th chords.
