Chopin shortened the initially written gminims in the violin part, replacing them with crotchets and rests. He also shortened b minims in cellos in a similar manner as well as modified the slur in the 1st violin part accordingly.

It is difficult to unequivocally prove where the difference between the pitch of the 3rd quaver in the accompaniment in FE (→EE) and GE came from. Both sources do not reveal any explicit traces of corrections. We assume that it is most likely that Chopin corrected the original (perhaps even erroneous) version of FE in GE. However, the evidence is inconclusive, hence we add a variant of the base source, FE, to the main text.
