In FC (→GE) there is no  raising a1 to a1 on the last quaver in the bar. According to us, the mistake could have already been committed by Chopin in [A]. It is indicated by overlooked naturals also in bar 43 – two oversights of the very naturals to a notes seem highly unlikely for a copyist; however, they are not unusual in Chopin's autographs, who would often mark alterations only the first time a given note appears in a bar.

composition: Op. 11, Concerto in E minor, Mvt II

..

In FE (→GE1), the top note of the 10th semiquaver is an a2 (with a ); ais then restored with a sharp at the beginning of the 4th beat in the bar. The unequivocal mistake of the engraver is confirmed by corrections in three out of four pupils' copies – FES, FEJ and FEH. Respective revisions were introduced also in EE and subsequent GE – in GE2, the erroneous  was changed to a , whereas in EE and GE3, both marks were removed.

As was the case with b. 3, of which this bar is a repetition in the manuscripts, not written out, in A (→FE,FCGE) there is no  restoring g1 in the bottom R.H. voice on the 3rd crotchet. The mistake was noticed only in EE.

In the last R.H. triplet, A (→FC,FE) contains only the  lowering d3 to d3. In GE and EE, a  was added before the next quaver (d2), yet the overlooked  restoring g2 on the last quaver of the bar is absent in all sources.

b in FC (→GE) & FE

b in EE

..

The version featuring b resulted from a mistake or inaccuracy by Chopin in [A] – the  to the 1st third was written there in such a way that both Fontana and the engraver of FE put it before d1, where it has no purpose. It must have been b, which, however, was noticed only in EE.
