| Construct a Fr+6 in C Major |
|
Definition
| The French sixth (Fr + 6 or Fr[image]) is similar to the Italian, but with an additional tone, 2: ♭6, 1, 2, ♯4; A♭–C-D–F♯ in C major. This chord is called "French" because its notes are all contained within the same whole tone scale, lending a sonority common to French music in the 19th century. |

It+6 This is the only augmented sixth chord comprising just three distinct notes; in four-part writing, 1 is usually doubled, because it is the only stable member of the chord. |

| How to avoid parallel fifths in Ger+6 resolution/use |
|
Definition
It is more difficult to avoid parallel fifths when resolving a German sixth chord to the dominant, V. These parallel fifths, referred to as Mozart fifths, were occasionally accepted by common practice composers. There are two ways they can be avoided: - The ♭3 can move to either 1 or 2, thereby generating a Italian or French sixth, respectively, and eliminating the perfect fifth between ♭6 and ♭3.[6]
- The chord can resolve to a "six-four" chord, functionally either as a cadential six-four intensification of V, or as the second inversion of I; the cadential six-four, in turn, resolves to a root-position V. This progression ensures that, in its voice leading, each pair of voices moves either by oblique motion or contrary motion and avoids parallel motion altogether. In minor modes, both 1 and ♭3 do not move during the resolution of the German sixth to the cadential six-four. In major modes, ♭3 can be enharmonically respelled as ♯2 if it resolves upwards to ♮3, similar in voice leading to the resolution of French sixth to the cadential six-four. This respelled chord is sometimes referred to as the English, Swiss or Alsatian sixth chord.[7]

Enharmonic equivalency of the French sixth (as in how to use it as a point of modulation) |
|
Definition
The French sixth has two characteristics in common with the diminished seventh chord: - Both chords are constructed of two superimposed tritones; in the French sixth, between ♭6-2 and 1-♯4. Thus, both have inversional symmetry;
- Both are enharmonically equivalent at the tritone; i.e., both chords transposed up or down a tritone will result in the same pitches as the original.
As with the diminished seventh chord, the latter property allows the chord to be used in modulating to very remote keys. For instance, ♭6, 1, 2, ♯4 could be reinterpreted as 2, ♯4, ♯5, ♯7, i.e., the French sixth of the ♯IV key area, displaced an interval of a tritone relative to the tonic key, I. |

Definition
In jazz, the French sixth sonority functions as a dominant instead of a predominant chord; exploiting the enharmonically equivalent property of the French sixth is a common technique is referred to as tritone substitution. The French sixth sonority, for example A♭, C, D, F♯ in the key of C, is interpreted as a specific variation of a dominant seventh chord in the following keys: - V7 of D♭ with ♯4; A♭ as the root: A♭, C, D, G♭; or
- V7 of G with ♯4; D as the root: D, F♯, G♯, C.
This chord is called the Lydian dominant (A♭7♯11, D7♯11). |
