b. 241-246

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

poco a poco cresc.  cresc. - - in GE2

..

The poco a poco crescendo indication, carefully planned by Chopin over six bars in A, was reproduced in GE1 in a similar way, yet less logical and legible: dashes combining particular elements of the indication and showing its destination ( in bar 247) were overlooked and particular words were regrouped, by doubling the cresc. indication, which appears in bars 243 and 244. FE repeated the notation of GE1, adding – perhaps at Chopin's request – dashes between particular parts of the indication (in bars 241-244). The last notation was subject to further, seemingly logical changes in EE, as a result of which, however, the crescendo seems to be terminating in bar 244. The notation of GE2 is closest to Chopin's intention; it repeated the indications of GE1, yet adding dashes after the last cresc. until bar 247.

b. 241-245

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

12 short accents in A (→GE)

11 short accents in FE

11 vertical accents in EE

..

In EE all accents in the R.H. in bars 241, 243 and 245 were printed as vertical ones, which was a frequent arbitrary decision of that edition.

The last accent in bar 245 was overlooked in FE (→EE).

Slur to 5th quaver in A

Slur to 4th quaver in GE (→FEEE)

..

The slur of A, clearly led to the 5th quaver, was shortened in GE (→FEEE), perhaps due to a graphical difficulty or misunderstanding of the crossed lines of the slur and the  hairpin.

b. 241-242

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

..

In A there are no flats lowering g1 to gat the beginning of bar 241 and at the end of bar 242. The first of them was added already in GE1 (→FEEE, →GE2), the second one – only in EE.

Staccato dot in A

No mark in GE (→FEEE)

..

The missing staccato dot in GE (→FEEE) is almost certainly a consequence of the oversight of the engraver of GE1.
