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, .
[1] [3] Irregular resolutions also include V 7 becoming an augmented sixth [specifically a German sixth] through enharmonic equivalence [1] or in other words (and the adjacent image) resolving to the I chord in the key the augmented sixth chord (FACD ♯) would be in (A) rather than the key the dominant seventh (FACE ♭) would be in (B ♭).
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.
For example, in the key of C major, the chord of G 7 is followed by a chord of C. In order to execute a tritone substitution, a common variant of this progression, one would replace the dominant seventh chord with a dominant chord that has its root a tritone away from the original:
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.
That is, in C major the Australian 6th might be F-Ab-B-D#, and the Sydney 6th would then be F-Ab-C-D#. I'm sure I've seen both in actual music, but examples are not particularly common. The 'Australian Sixth' is just an inverted enharmonic half-diminished seventh chord and the 'Sydney Sixth' is just an inverted enharmonic minor seventh chord.

The Jupiter example is unique in that Mozart spells the fifth enharmonically (A ♭ /D ♯ to G/D ♮) as a result of the progression arising from a B-major harmony (presented as a dominant of e-minor). Theorists have tried to make the case that this resolution of the augmented sixth chord is more frequently acceptable. "The parallel fifths [in ...
