b. 649

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

​​​​​​​in FE (→EE)

​​​​​​​ in GE

..

Both the change of indication from  to  and omission of the accent are most probably mistakes of the engraver of GE, although it is easier to imagine an overlooked 'z' in ​​​​​​​ at the time of reading the autograph, hence in FE. Therefore, it is possible that one or both inaccuracies were initially present in FE, in which, however, Chopin corrected them in the last phase of proofreading.

b. 649

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

L.H.  ​​​​​​​in FE (→EE)

No marking in GE

Long accent for both hands suggested by the editors

..

As a result of comparison of the indications of FE in bar 646 and 648-650, we interpret the mark in this bar as a long accent, referring to both hands. The absence of the mark in GE is most probably an oversight of the engraver.

In FE, there are no sharps raising g2 to g2 (in both bars) and c3 to c​​​​​​​3 (in bar 649). In GE1 (→GE2), the first two were added; the notation in EE and GE3 is fully correct.

Just like in b. 198, of which the discussed bar is an exact repetition, the version of A (→FEEE) is the original version, changed by Chopin in that bar in FC (→GE).
