NEAPOLITAN-SIXTH CHORDS
����II
6 (or N
6) = a major triad built on
���� �� ��2
functions as a dominant preparation chord moving to V, especially at cadences
� more common in minor, because the chord 5th is diatonic to minor (�6 in minor, ��6 in major)
� usually in 1st inversion, with �4 in bass, to avoid the tritone root motion from ��2 to �5
� usually the third of the chord (the bass) is doubled, since the root is chromatically altered
� it is often approached from the VI chord a perfect 5th away
voice-leading:
� ��2 (root of chord) usually moves down to �7 (3rd of V)
� �4 (3rd of chord) is normally doubled: one note moves up to �5 or remains (as root or 7th of V7),
and the other moves down to �2 (5th of V)
� (�)�6 (5th of chord) moves down to �5 (root of V)
passing chords between ����II6 and V:
sometimes resolution to V is preceded by a cadential 64 or viiº7/V
when this happens, ��2 passes through �1 on its way to �7
for comparison: examples of common dominant preparation chords
Note that these all contain scale degrees �4 and �6,
the characteristic pre-dominant degrees that surround �5,
and either �1 (a third above �6) or �2 (a 3rd below �4), or both �1 and �2.
All of these chords usually function the same way: to prepare V.

AUGMENTED-SIXTH CHORDS
construction:
� built on the note a semitone above the goal note, which is usually �5 (��6 in major, �6 in minor)
� like Neapolitan 6ths, augmented 6ths are more diatonic to minor than major
� like Neapolitan 6ths, augmented 6ths usually act as pre-dominants (but can also be dominants)
� the chord is named for the interval of an augmented 6th above the bass note: (�)�6 to
��4
resolution of aug. 6th to 8ve
+6 P8
assorted pre-dominants moving to V

5/V V �II
6 V Fr
+6 V
different types:
all augmented 6th chords have, at minimum, a major 3rd (the tonic of the key) above the bass note
and an augmented 6th above the bass note (��4 of the key)
� It.6 has only three notes: bass, major 3rd, and augmented 6th (
�63 ):
(�)�6, �1,
��4
� Fr.6 has those three notes plus an augmented 4th (
�6

): (�)�6, �1, �2,
��4
� Ger.6 has those three notes plus a perfect 5th (
�65 ):
(�)�6, �1,
(�)�3,
��4
the rhyme “I, F, G; 1, 2, 3” may help you remember which scale degrees are part of which chord
� the “Swiss” 6th, or doubly aug. 4th chord, has the basic 3 notes plus (surprise!) a doubly aug.

the Italian, German, and “Swiss” aug. 6th chords are enharmonically equivalent to

the French aug. 6th is enharmonically equivalent to a dominant 7th chord with flatted 5th

voice-leading:
� the interval of the aug. 6 resolves outward by half step to an 8ve on �5 (��6 goes down;
��4 goes up)
these notes are tendency tones that function as double leading tones in contrary motion
� �1 resolves down to the leading tone, and is doubled in the It.+6
(moving to �2 as well as �7)
� be careful to avoid parallel P5s in resolving a Ger. +6
directly to the dominant
common ways to avoid this problem are:
- move first to a cadential
64 or other passing chord
- leave the fifth out of the V chord
- arpeggiate the chords
- change the Ger. +6
to an It.+6
(i.e., leave out the 5th) before resolving it

� to V7, with the notes of the augmented 6th moving down in parallel by semitone to a minor 7th
� the aug. 6th may be inverted to a dim. 3rd that resolves inward (rather than outward) to an 8ve
� one of the other notes of the chord might be in the bass (not shown, but you can imagine it)
� to a non-dominant chord (more on this later)

Summary:
• Notes of augmented 6th typically resolve in contrary motion by ½ step to 8ve
(or in parallel motion down by ½ step to dominant 7th)
• In pre-dominant augmented 6th, ��6 and
#�4 resolve to �5
• Other possible chord tones: major 3rd; augmented 4th OR perfect 5th

DOMINANT-FUNCTION AUGMENTED-6TH CHORDS
Through the 18th and early 19th centuries, most aug.-6th chords functioned as pre-dominants,
with ��4 and
(�)�6 resolving to �5 as part of a dominant harmony. In later 19th-century music, dominant-
function aug. 6th chords aree increasingly common, with ��2 and �7 resolving to �1 as part of a tonic triad.
