b. 636-637

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

Slurs in FE (→EE)

Slurs in GE

..

The slurs of FE (→EE) are probably inaccurate, since it is difficult to find a reason that would justify their different range – cf. bars 621-629 and the remaining ones in this fragment. However, it has to be said that if it were not for the ratio of the number of one type of the slurs to the other, it would be the slurs of FE, encompassing the entire motifs, that could be considered to be more accurate.

b. 636

composition: Op. 31, Scherzo in B♭ minor

in A (→FEEE)

No sign in FC (→GE)

..

In both manuscripts, this bar is a literal repetition of b. 185 (it is not written out in full), and like there, the oversight of a  sign in FC resulted in GE lacking it.

b. 637-642

composition: Op. 39, Scherzo in C♯ minor

Three long accents in EE

Six accents in GC

Long accents in FE

Short accents in GE

Our suggestion

..

Just like in the previous three bars, in the main text we present long accents as the same can be found in EE and FE, while the GC notation is ambiguous (GE has short accents). Moreover, bars 634-642 have the same shape in every source. In GC the marks are notated above the LH octaves. It seems little probable this is not consistent with the autograph. However, in GE the accents are notated below the octaves, which makes us cautious when it comes to evaluate the remaining sources, where the accents are placed between the staves. No accents in bars 639, 641-642 in EE might have resulted from negligence.

b. 637-642

composition: Op. 39, Scherzo in C♯ minor

Pedalling in EE

No markings in GC (→GE)

Pedalling in FE

..

In the main text we provide the FE pedalling, most probably the latest, and according to us more justified when it comes to dynamics (Chopin rarely marked changes in pedalling every strike of a note). Pedallling markings in GC (→GE) must have been overlooked.

b. 637-644

composition: Op. 39, Scherzo in C♯ minor

in bar 637 in EE & GE

in GC

No indication in FE

Our suggestion

..

The stretto ​indication was most precisely written out in GC, where we know exactly the scope of the notated dashes. Neither EE nor GE shows it with scu precision. In FE there is no indication at all. However, we believe that the scope indicated in GC was not really based on Chopin's intention as it would be virtually impossible to perform crotchets in bars 643-644. Therefore, assuming the notation of GC is imprecise, we suggest limiting the scope of stretto only to bars 637-642.
