b. 648-657

composition: Op. 31, Scherzo in B♭ minor

No markings in A (→FEEE)

Pedalling in FC (→GE)

..

In the main text we give the pedalling entered by Chopin into FC (→GE) in b. 197-206 and valid also here due to the abridged notation of the discussed bars.

composition: Op. 39, Scherzo in C♯ minor

Separated pauses in EE & GE

Common pause in GC & FE

..

The authentic notation may not have included a separate fermata below LH, as it does not appear neither in GC nor in FE. The lower fermata in GE must be a revision, so it must have also been added in EE. Both notations are equivalent but to be precie and formal we supplement the fermata in the main text.

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.

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.
