b. 252-253

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

Slur to bar 253 in A

Slur only in bar 252 in GE (→FEEE)

..

In A the slur at the end of bar 252 (the last one on the page) indicates an intention to lead it to the next bar, where the slur's ending was not written though. Perhaps it was the reason, together with an interrupted continuity of the sign caused by an uneven ink outflow, why the slur was shortened in the editions.

b. 252-253

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

No marks in A & FE (→EE)

Staccato dot in GE1

3 dots in GE2

..

An additional staccato dot in GE1 seems to be a mistake, since it is absent in A (cf. bars 249-250). On the other hand, it is the last bar on the page in A, which fosters the appearance of inaccuracies, hence it cannot be excluded that Chopin forgot a dot or dots. The dot is absent in FE (→EE), which may be explained by a mistake, this time of the engraver of FE, by its removal by Chopin in FE or by its addition in the last phase of proofreading of GE1, not included in FE (according to us, Chopin's proofreading is highly unlikely). In this uncertain situation, in the main text we give the version of A, yet the version of GE1 (and even of GE2) may be regarded as potentially corresponding to Chopin's idea.

 in A

No sign in GE (→FEEE)

The missing  in the editions certainly do not correspond with Chopin's intention. The engraver of GE1 may have considered that it would be impossible to reproduce the sign written on notes in A in print.

Slur to b1 in A (→GE)

Slur to a1 in FE (→EE)

..

A Chopin proofreading of the end of the slur in FE (→EE) is uncertain. However, even if the version of FE is an inaccurate reproduction of GE1, the slurs can be considered a contextual interpretation of the slur of A, due to the continuity of the figurations of the R.H.

According to us, all versions of the editions are a result of consecutively overlapping inaccuracies and misunderstandings. In GE the signs were related only to the notes on the bottom stave, which was then inaccurately reproduced in FE and EE.
