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

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, �1, �2,

� Ger.6 has those three notes plus a perfect 5th (

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

Page 7: Neapolitan 6ths and augmented 6ths

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.
