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

 to a somewhat unsteady I

 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.
