The \transpose operation changes *all* the pitches in \notesA, including the c' 
that tells LilyPond what the instrument \transposition is.

(\transpose really should not change this pitch, and there is a bug listed 
about 
this. http://code.google.com/p/lilypond/issues/detail?id=754)

The effect is that \transpose will change the written pitches, but leave the 
sounding pitches the same.  Quotes with \quoteDuring use the sounding pitches.

I do not know a way to do what you want with \quoteDuring.  (I just use 
variables to hold short motives instead.)  A similar issue must have been 
handled to make the function \transposedCueDuring, so that might serve as a 
model if any Scheme programmer (as many users seem to be) wants to find a 
solution.
