Other variants of augmented sixth chords can be found in the repertoire, and are sometimes given whimsical geographical names. Both Italian and German variants are enharmonically identical to dominant seventh chords. The augmented sixth interval is typically between the sixth degree of the minor scale, ♭, and the raised fourth degree, ♯.

[30][need quotation to verify] Like the typical +6, this enharmonic interpretation gives a resolution irregular for the half-diminished seventh but normal for the augmented sixth, where the two voices at the enharmonic major second converge to a unison or diverge to an octave. These chords contain an augmented sixth interval which has a strong pull outward to resolve to an octave on the fifth scale degree. The Neapolitan 6th is a chromatic chord built on the flattened supertonic of a key. Le is typically the bass note, and in a four-voice texture, do is typically the pitch that is doubled. So do you know your augmented 6th chords? Thus a C6 is C, E, G, A . Hanson, Howard. This chord has its origins in the Renaissance,[2] was further developed in the Baroque, and became a distinctive part of the musical style of the Classical and Romantic periods.[3]. 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 distance in pitch remains the same, but the interval is expressed differently and so leads to the new key: Share this post: Benward, Bruce, and Marilyn Nadine Saker (2008). https://en.wikipedia.org/w/index.php?title=Augmented_sixth_chord&oldid=981101930, Articles with unsourced statements from November 2018, Wikipedia articles needing factual verification from March 2015, Creative Commons Attribution-ShareAlike License, From the German sixth chord, lower any factor by a semitone so that the result is, From the French sixth chord (or minor seventh chord posing as augmented sixth), there exists a factor which, when lowered by semitone, gives a result equivalent to a, From the half-diminished seventh chord as augmented sixth, there exists a factor which, when lowered by a semitone, is equivalent to a diminished seventh chord at the interval one semitone lower than the diminished seventh chord which started the, This page was last edited on 30 September 2020, at 08:47.

There are four distinct types of chords within this category (although the origin of their monikers is uncertain): the Italian 6th (It6), the French 6th (Fr6), the German 6th (Ger6), and the Swiss 6th (Sw6). All share the same voice-leading pattern going directly to a root position V chord. In the major mode, the chromatic voice leading is more pronounced because of the presence of two chromatically altered notes, ♭ and ♯, rather than just ♯. And if you want to make a minor 6th chord you flatten that third and you have C, Eb, G, A . Notable examples include the themes of the slow movements (both in variation form) of the opp. The Neapolitan 6th Chord. Although augmented sixth chords are more common in the minor mode, they are also used in the major mode by borrowing ♭ of the parallel minor scale.[4]. Does it have tenden… +6 chords are based on resolving to an octave by half steps in contrary motion. From the Baroque to the Romantic periods, augmented sixth chords had the same harmonic function: as a chromatically altered predominant chord (typically, an alteration of ii 3, IV 5, vi or their parallel equivalents in the minor mode) leading to a dominant chord. The first examples, from the first movement of Beethoven's Fifth Symphony, shows an Italian augmented sixth chord (It+6 It + 6) in C minor with the “classical” spelling. [17] He described the augmented sixth chords to be inversions of the diminished triad and of dominant and diminished seventh chords with a lowered second degree (♭), and accordingly resolving into the tonic. There are two ways they can be avoided: In major modes, ♭3 can be enharmonically respelled as ♯, allowing it to resolve upwards to ♮. [4][5][6] According to Kostka and Payne, the other two terms are similar to the Italian sixth, which, "has no historical authenticity-[being] simply a convenient and traditional label."[7]. : C–B♭ in C–E♭–G♭–B♭) can be written as an augmented sixth (C–E♭–G♭–A♯). In the late Romantic period and other musical traditions, especially jazz, other harmonic possibilities of augmented sixth variants and sonorities outside its function as a predominant were explored, exploiting their particular properties.

Simon Sechter explains the chord of the French sixth chord as being a chromatically altered version of a seventh chord on the second degree of the scale, . However, this may be used as the derivation of the augmented sixth chord. For example, in the key of C, the German sixth chord could be reinterpreted as the applied dominant of D♭. The French augmented-sixth chord has four members: le, do, re, and fi. In this case, however, the seventh of that Ab7 (the note Gb or F#) does not resolve up to G, but rather it planes down to F (the seventh of the G7). These parallel fifths, referred to as Mozart fifths, were occasionally accepted by common practice composers. replaces a Roman numeral. Having explored the broad concept of the "pre-dominant" chord in the previous chapter, we can now look at two vitally important pre-dominant chords, the Neapolitan 6th and the Augmented 6th chords.This page covers the N6 type. The upper voice continues upward with a long appoggiatura (G♯ to A). tonic, passing, etc.) Thus, doremains as the only tone that can be doubled in strict style, and this doubling typically carries into freer styles, as well.) This characteristic has led many analysts[15] to compare the voice leading of augmented sixth chords to the secondary dominant V of V because of the presence of ♯, the leading-tone of V, in both chords. The following "curious chromatic sequence",[24] graphed by Dmitri Tymoczko as a four-dimensional tesseract,[25] outlines the relationships between the augmented sixth chords in 12TET tuning: The minor seventh chord may also have its interval of minor seventh (between the root and seventh degree (i.e. Augmented Sixth Chords come in three forms: German, French and Italian.

In Classical music, however, it appears in much the same places as the other variants, though perhaps less often because of the contrapuntal difficulties outlined below. rarely, augmented sixth chords are found transposed down a perfect fifth, analyzed as “on flat two,” and used to approach a tonic chord in root position. All three of the chords include the major 3rd interval and the augmented 6th interval above the root note, but have differences in the other note added: The Italian Sixth is the simplest of the three versions as it uses just the 3 basic notes from the augmented 6th chord: Here is a very famous example of an Italian sixth taken from Beethoven’s Symphony No. All variants of augmented sixth chords are closely related to the applied dominant V7 of ♭II.

An example of this is through the "reinterpretation" of the harmonic function of a chord: since a chord could simultaneously have more than one enharmonic spelling with different functions (i.e., both predominant as a German sixth and dominant as a dominant seventh), its function could be reinterpreted mid-phrase. Augmented sixth chords are typically built on the flattened submediant (the 6th note of the scale) [27] Again like the typical +6, this enharmonic interpretation gives a resolution irregular for the minor seventh but normal for the augmented sixth, where the two voices at the enharmonic major second converge to a unison or diverge to an octave. 2. They are very useful in modulation to different keys and have been used in various forms since the Renaissance period.

[13] Such anomalies usually have alternative interpretations. The augmented sixth chord can either be (i) an It+6 enharmonically equivalent to a dominant seventh chord (with a missing fifth); (ii) a Ger+6 equivalent to a dominant seventh chord with (with a fifth); or (iii) a Fr+6 equivalent to the Lydian dominant (with a missing fifth), all of which serve in a classical context as a substitute for the secondary dominant of V.[21][22]. This heightens both chromaticism by making possible the tonicization of remotely related keys, and possible dissonances with the juxtaposition of remotely related keys. There are two progressions – one in major, one in the parallel minor – for each of the three variants of this unusual chord. He notes that, "some theorists insist upon [augmented sixth chord's] resolution not into the tonic but into the dominant triad, and regard them as being erected not on the altered 2nd degree, but on the altered 6th degree in major and on the natural 6th degree in minor", yet calls this view, "fallacious", insisting that a, "chord of the augmented sixth on the 6th degree is nothing else than a modulatory degression into the key of the dominant".[16].
