Adding in FE the b
note on the 2nd beat of the bar to the top voice is probably a result of misunderstanding of the notation of [A]. The different value of the b note in bar 59, being a repetition of this bar, not written out with notes in the manuscripts, indicates an inaccuracy of reproduction of the manuscript in this place by the engraver of FE. Unifying the rhythmic values in EE is most probably a revision, supported by a comparison with bar 59. In the main text we give the unquestionable version of GC (→GE).
