Here's your chart; "r" indicates a repeat
FIVE PART RONDO:
A1 - m. 1-8, ends with a PAC in I, trpt and organ
rA1 - m. 9-16, PAC (I), organ only
B - m. 17-24, HC (I), both
rB - m. 25-32, HC (I), organ only
A2 - m. 33-40, PAC (I), both
rA2 - m. 41-48, PAC (I), organ only
C - m. 49-56, HC (I), both
rC - m. 57-64, HC (I), organ only
A3 - m. 65-72, PAC (I), organ only
rA3 - m. 73-80, PAC (I), both
This rondo is not a typical five-part rondo, in that it never modulates away from tonic. In both the B and C sections applied chords are used, but never to the extent which usually defines a modulation. The ends of both these sections have a very half-cadence-y feel.
Also notably different is that each section repeats individually. This would probably make it more difficult to perform, because one typical rule of performance is that every repetition has to bring something new and exciting to the listener's attention. It is likely, though, that this may have been more for ceremonial or social purposes, and then the music would have been danced to, which means the performance doesn't require as much noticeable variety since people won't be listening all that hard.
