Timothy Cutler On Voice Exchanges
Perceiving G minor as a principal structural moment in the Sarabande
leads to another long-range relationship: the lowest pitch in m. 16, the vio-
lin’s open G-string, forms a strong aural association with the bass G of the
neapolitan in m. 22. This points to another form of the 5–6 motive, with
the fifth of the G-minor harmony rising to a flattened sixth, and defines
mm. 16–22 as an area of predominant expansion. After this lengthy and
deep-level accumulation of predominant tension, it may not seem appropriate
for the neapolitan to resolve through VII
4
3
to a somewhat unsteady I
6
chord.
It is here that the concept of the inverted cadential six-four is so valuable,
because the “I
6
” in m. 23 is not a first-inversion tonic harmony but instead
a chord possessing dominant function. This permits the prolongation of IV,
with its chromatic 5–6 offshoot ≤II
6
, to progress to its desired location, the
dominant (Example 27).

What does all of this mean for the original voice-exchange hypothesis
in mm. 21–22? In the speculative analyses shown in Examples 23 and 25, this
pitch swap was deemed unsound because the starting and ending points of
the exchange did not share similar harmonic function. however, these inter-
pretations ignore another pertinent clue that occurs during the first eight
measures—the twin voice exchanges that coincide with the bass’s descend-
ing octave. having affiliated mm. 16 and 22, which both feature prominent
GΩ’s in the highest and lowest registers and bring about a 5–6 motion in an
upper voice, one can compare the downbeats of mm. 22 and 21 to uncover
another connection to m. 16. Implied on the downbeat of m. 16 is a B≤ that
occurs literally a few beats later. These pitches in m. 16, G and B≤, form a
voice exchange with B≤ and G in m. 21, which in turn trade pitches with
m. 22, producing a twin voice exchange to complement the same idea in
mm. 1–8 (Example 28).
What remains is to clarify the harmony on the downbeat of m. 21. It
turns out that its surface role is an illusion, and its function on a deeper
level is quite different (Example 29). c≥ and E, which generate the “VII

”
29 The explicitness the voice exchange associated with the
inverted cadential six-four depends on one’s interpretation
of the third beat of m. 23. If one hears F remaining in the
upper voice when beat 3 arrives, as does Schumann in his
piano accompaniment for the Sarabande, one can depict
an implied voice exchange as shown in Example 27. If one
hears E when beat 3 enters, creating a 4–3 suspension in an
inner voice, the exchange is more conceptual in nature.
