In most instances, however, the implied polyphony is more subtle than the systematic arpeggiation shown above. The "melodic" line in the following example outlines, in additon to the "continuo" pitch, two (or more) levels of polyphony within the "solo" line (figure 2):

It is the job of the arranger to determine which leaps are rhetorical (melodically expressive), which leaps imply polyphony (or some kind of dialog), and which leaps literally represent the lower voice. In the example just given, the middle staff perhaps represents the best notational solution. The supporting lower part is independently marked, while the implied polyphony and rhetoric of the "solo" line is left to the interpretation and fingering of the performer (or the editor).

1.3 Multi-Stopped Chords
A multi-stopped chord is, of course, a literal polyphonic event rather than an implied one, and is treated as such in the unaccompanied string works. In the works for violin, prolonged passages of double, triple and even quadruple-stopped chords not only are common, but routinely accommodate highly consistent voice-leading. The following passage, for example, is only a small portion of a prolonged multi-stopped passage of some thirty-two measures' duration (figure 3):
 | Figure 3. Fuga, G-minor Violin Sonata (bwv 1001), mm. 27-32.
|
On the relatively few occasions that faulty voice-leading is encountered in the violin works, it is usually the result of a technical compromise in a passage of quadruple-stopped chords. In the following passage, for example, the inner voices are exchanged due to fingering limitations of the instrument, resulting in a faulty resolution of the penultimate 4/3 harmony (not to mention a quite unusual voicing) (figure 4):
 | Figure 4. Sarabande, B-minor Violin Partita (bwv 1002), mm. 11-2.
|
The treatment of multi-stop chords in the unaccompanied cello works is considerably less consistent, due to a less facile technical idiom. Quadruple-stopped chords almost always result in faulty voice-leading and triple-stops often lack satisfactory resolutions as well. Even some double-stopped passages are problematic, as in the following example (figure 5):
 | Figure 5. Sarabande, Cello Suite 2 (bwv 1008), mm. 21-8.
|
Such multi-stopped verticalizations, containing unresolved and even doubled tendency-tones, are found throughout the cello works. Representing a compromise between sonority on the one hand and an implied polyphony on the other, clearly these situations result from the technical idiosyncrasies of the cello. Indeed, in the following example the low c on the downbeat of measure 15 cannot be resolved downwards in register, since it is already the lowest note possible on the cello (figure 6):
 | Figure 6. Sarabande, Cello Suite 2 (bwv 1008), mm. 21-28. |
At times Bach's desire for an expressive sonority overrides considerations of harmonic function. An example of this is; the ubiquitous cadential 4/2 harmony, a dramatic structural marker found often in the preludes (where it is often marked with a fermata). In the prelude to the G-major Cello Suite, however, this dissonant harmony cannot be resolved in register because, again, the lowest note of the chord is the lowest note possible on the cello. In this case, Bach simply proceeds as though the harmony had not even occurred (figure 7):
 | Figure 7. Prelude, Cello Suite 1 (bwv 1007), mm. 19-24.

1.4 Polyphonic Integrity
Despite compromises of the type noted above, the multi-voice textures projected in Bach's unaccompanied cello lines are genuine contrapuntal structures, which accommodate a high degree of polyphonic integrity. In figure 8, I have re-notated the opening measures of the Allemande from the C-minor Cello Suite (bwv 1011), according to the following scheme (incidently, Bach's solution can be seen in figure 10):
 | Figure 8. Allemande, Cello Suite 5 (bwv 1011), mm. 1-5.
|
As can be seen, Bach's original line demonstrates a high degree of polyphonic integrity. It does not, however, present a high degree of textural integrity when transferred to an instrument capable of actually realizing, rather than implying, a consistent polyphonic structure. Transfer to a harmonic instrument such as the guitar, then, is not simply a matter of re-stemming the original. Such a process addresses neither the inherent voice-leading inconsistencies of the original nor the idiomatic characteristics of the receiving instrument. Taken to a conclusion, such pitch-faithful arrangement succeeds only in superimposing the limitations or weaknesses of one instrument onto another, without substituting for this deficiency with expressive means idiomatic to the receiving instrument. The likely result is an arrangement expressively inferior to the original.
An appropriate approach to arranging this music for the guitar, therefore, comprises the reconstruction of the polyphony in a contrapuntally and harmonically-consistent form, the reconstruction of the texture of the solo sonata (an expressive solo line supported by a slower-moving, yet rhythmic, "continuo" line), and the realization of these goals in an expressive form idiomatic to the guitar.

1. Of the six Partiten and Sonaten for unaccompanied violin (bwv 1001-6) and the six Suitten for unaccompanied cello (bwv 1007-12), Bach made alternate versions of the following: 1) the Suite for Cello in c-minor (bwv 1011) was set in g-minor for the lute (bwv 995); 2) the Partita for Violin in E-major (bwv 1006) was also set for lute (bwv 1006a); 3) the Fuga from the G-Minor Violin Sonata (bwv 1001) exists in versions for lute (bwv 1000) and organ (bwv 539); 4) the A-minor Violin Sonata (bwv 1003) was arranged as the Clavier Sonata in d-minor (bwv 964); 5) the Adagio from the C-major Violin Sonata (bwv 1005) was given a clavier setting in G-major (bwv 1005); 6) the Preludio from the Violin Partita in E-major (bwv 1006) was used as an orchestral Sinfonia in two cantatas: Wir danken dir, Gott, wir danken dir (bwv 29) and Herr Gott Beherrsher aller Dinge (bwv 120a). Amongst Bach's contemporaries, the lutenist Johann Christian Weyrauch made a French lute intabulation of the G-minor Violin Fugue, and several anonymous intabulators produced lute versions of the C-minor Cello Suite and E-major Violin Partitia.

3. The technique is encountered in the early seventeenth-century vocal concerti and instrumental canzone of Ludovico Viadanna, where a pseudo-polyphony is projected by one or more self-imitating voice parts and, in a more developed form, in the later seventeenth-century Corelli-type sonate a due, in which the solo violin simulates the trio texture of the sonate a tre through the use of multi-stops, arpeggios and disjunct scale motion. [ return to text ]
4. The autograph, by Anna Magdelena Bach, employs a scordatura notation in which the highest string of the cello is notated with respect to finger placement rather than to sounding pitch. To facilitate comparison with Bach's version for the lute, the version given here has been transposed to a-minor (the key most commonly used for performance of this work on the guitar) and adjusted to take account of the scordatura. A written a will now be the lowest sounding note on the cello. [ return to text ]
