The augmented sixth interval is typically between the sixth degree of the minor scale, ♭, and the raised fourth degree, ♯.With standard voice leading, the chord is followed directly or indirectly by some form of the dominant chord, in which both ♭ and ♯ have resolved to the fifth scale degree, .
The augmented sixth chord can either be the Italian sixth It +6, which is enharmonically equivalent to a dominant seventh chord without the fifth; the German sixth Gr +6, which is enharmonically equivalent to a dominant seventh chord with the fifth; or the French sixth Fr +6, which is enharmonically equivalent to the Lydian dominant without the ...

This works because diminished seventh chords are structurally equivalent in all of their inversions (a stack of minor thirds), so any note in a diminished seventh chord can be seen as the root note. The most important irregular resolution is the deceptive cadence , [ 3 ] most commonly V 7 –vi in major or V 7 –VI in minor.
However, this does not mean that these notes must be played within an octave of the root, nor the extended notes in seventh chords should be played outside of the octave, although it is commonly the case. 6 is particularly common in a minor sixth chord (also known as minor/major sixth chord, as the 6 refers to a major sixth interval).
Augmented sixth Play ⓘ.. In music, an augmented sixth (Play ⓘ) is an interval produced by widening a major sixth by a chromatic semitone. [1] [4] For instance, the interval from C to A is a major sixth, nine semitones wide, and both the intervals from C ♭ to A, and from C to A ♯ are augmented sixths, spanning ten semitones.
The chord is an augmented sixth chord, specifically a French sixth chord, F–B–D ♯-A, with the note G ♯ heard as an appoggiatura resolving to A. (Theorists debate the root of French sixth chords.) The harmonic function as a predominant is intact, with the chord moving to V7.
The Italian augmented 6th chord (It+6) is one example, from which proceed the French augmented 6th chord (Fr+6) and German augmented 6th chord (Gr+6) by addition of one note. Rawlins (2005) asserts that the notion derives from practice of such composers as Eric Satie , Claude Debussy , Maurice Ravel , and Gabriel Fauré , and was first used in ...
