There is a difference between what Bach did for the performance that 
the parts were prepared for, and what he'd have done with ideal 
performing forces and plenty of time to copy parts.

And, of course, why would Bach have copied ripieno parts, or parts 
indicating solo/ripieno for a performance he knew would not have 
anything but solo singers? If I'm remembering correctly, aren't there 
some sets of cantata parts where the solo parts were prepared at one 
time and the ripieno parts later? That strongly suggest an early 
performance with only solo singers, but the ripieno parts prove that 
Bach's conception of the work included the possibility of ripienists, 
despite the fact that the original set of parts lacked them. Perhaps 
some of the sets of parts without ripieno indications might later 
have been adapted by Bach had he an opportunity to perform it with 
more than one singer on a part (either by adding ripieno/solo 
indications in the existing single part for two singers to sing from, 
or by copying ripieno parts for one or more singers to use).

It's really rather analogous to the situation with the Mozart 
fragments. Before Tyson's revolutionary breakthrough on the paper 
types in the fragments (where he showed that some complete Mozart 
works were started long before they were completed, with the first 
few folios of the score being on paper from years earlier, such that 
these works lay as fragments for years before Mozart returned to them 
and finished them), it was often wondered why Mozart had "abandoned" 
so many works for which the beginnings seemed so promising. Well, it 
turns out that, apparently, Mozart would sometimes begin a work and 
get down enough to recall the work, then lay it aside for later 
completion. Sadly, he never got around to finishing many of them. 
Thus, we cannot say for certain that Mozart had abandoned any of his 
fragments, only that they were works that he'd not yet had the 
opportunity to complete.

Likewise, the surviving parts for Bach's vocal works don't 
necessarily represent Bach's final state for a "complete" set of 
performing parts for those works, as we know perfectly well that when 
performing works a second and third time, he sometimes had additional 
parts prepared *according to the forces available at the time*.

For this reason, I just can't accept any dogmatic assertion that a 
surviving set of solo-only vocal parts precludes choral performance.

In a similar example from a later period, it's pretty clear from 
surviving parts for Mozart piano concertos in Leopold Mozart's hand 
(I believe they are at St. Peters, and Cliff Eisen prepared an 
edition for B&H from them that was recorded by Robert Levin at the 
fortepiano, but I can't recall what period orchestra was involved -- 
I actually don't own any of these recordings) that there were oral 
ripieno/solo traditions even in that repertory, since Leopold's parts 
include some striking effects with solo/ripieno markings (not always 
simply corresponding to obvious loud/soft associations between tutti 
and solo). 

There is so much that we don't know and that was not included in 
notated parts that I just think it's not possible to preclude 
multiple singers on a part for particular Bach's vocal works just 
because the only surviving parts for those works include no 
indication that more than one singer was used in the performance(s) 
Bach supervised.

To me, what Rifkin did was to legitimize one-on-a-part performance of 
Bach's music, but his work certainly does not make performance with 
more than one-on-a-part illegitimate.

His interpretation may be correct for certain sets of sources insofar 
as they discribe the way Bach actually peformed them, but that really 
should not completely restrict us to those exact same limitations in 
our own performances. Describing what was done does not proscribe 
what can be legitimately done.

That's why I find Rifkin's dogma problematic. I've prepared parts for 
string quartet performances of opera excerpts. We only ran off one 
part per instrument (which wouldn't really tell a future musicologist 
whether one or two players played from it). But had we more players, 
we could have printed more parts. Naturally, it's much easier for us 
to print or photocopy additional parts than it was for Bach to copy 
additional parts, but the point is we prepared the parts we needed 
for the performers we had, not for the performers we would have used 
had we had them.

The main question here is: what does the evidence tell us? Does it 
limit possibilities for our historically informed performances, or 
does it only provide information on one (or a handful of) 
contemporary performance(s)? I think it is really more often the 
latter than the former, though, of course, cases can be made for 
going beyond that in the cases of specific sources. I believe the 
sources provide evidence for a continuum of possibilities, rather 
than limiting us to only one possible set of performing forces.
