b. 415-416

composition: Op. 21, Concerto in F minor, Mvt III

No slur in sources

Slur suggested by the editors

..

According to us, the absence of the slur in the L.H. is a result of Chopin's oversight: a respective slur is present in all three similar places, in bars 423-424, 455-456 and 463-464.

b. 415-416

composition: Op. 21, Concerto in F minor, Mvt III

3 long accents in A & FE

 & > in GE1

3 short accents in EE & GE2

..

Three clearly long accents written in A were reproduced in GE1, without any apparent reason, in an explicitly varied manner. However, FE restored the notation of A, which could be seen as Chopin's proofreading. Both in EE and GE2 the Chopinesque long accents were reproduced as common short accents.

b. 415

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

..

FEH includes a two-stage entry, which first added a  raising e1 to e​​​​​​​1, and then corrected that erroneous improvement.

Short accent in EE & GC

Long accent in FE

Accent in GE

..

The length of an accent used here remains an unsettled issue -  short in EE and GC or long in FE (also in subsequent bars - compare bars 418-431). For GE we adopt a short accent just like GC, and the fact that the accent is placed under the RH part must have been the engraver's arbitrary decision.

No tie in EE

c tied in GC (→GE) & FE

Our variant suggestion 

..

Even though EE is the only one without a tie on c, we believe this version to be authentic and propose to have a variant bracketed tie for the main text.
