b. 3-19

composition: Op. 49, Fantaisie in F minor

..

One of the intriguing features of FCs is the almost complete absence of augmentation dots in  groups. The dots are present only in bar 3 next to d2, in the 2nd half of bar 9 (all necessary ones), in bar 17 next to the e1-g1-b1-e2 chord and in bar 22 next to a1, which means that 56 dots were omitted. It could be a feature of Chopin's sketch autograph reproduced by Fontana or facilitation applied by the copyist, who, perhaps, was copying it under time pressure. We prefer the former – if Fontana had been omitting dots due to time pressure, he could have added them later. On the other hand, since he was copying Chopin's incomplete and, consequently, ambiguous notation, he could be afraid that he might guess it incorrectly.
In the edited FCs version we provide, we add all these dots after the final version.

If the Chopinesque sketch was actually devoid of dots, one could assume that Chopin first wrote bare quavers in these places and then added semiquaver beams "en bloc", omitting the majority of dots due to their obvious nature in this situation.

b. 3

composition: Op. 49, Fantaisie in F minor

e1-c2 in A (→GE) & FE2 (→EE)

e1-b1 in FE1

..

The FE1 version featuring b1 as the topmost note must be erroneous and was corrected – perhaps by Chopin – in FE2 (→EE).

b. 3-4

composition: (Op. 4), Sonata in C minor, Mvt III

   in A

   in GE (→FE,EE,IE)

..

The changes concerning the range of the dynamic hairpins introduced by GE (→FE,EE,IE) are arbitrary and rather unfounded if we take into account the natural phrasing, considering the direction of the melody and harmonic tensions.

b. 3

composition: (Op. 4), Sonata in C minor, Mvt II

Slur to c in A (→GEFE,IE)

No slur in EE1

Slur to d in EE2

..

Both the missing slur in EE1 and the shorter EE2 slur are the engravers' mistakes.

b. 3

composition: (Op. 4), Sonata in C minor, Mvt II

Staccato dot in A

No mark in GE (→FE,EE,IE)

..

The missing dot is most probably due to an oversight by the GE engraver (→FE,EE,IE).
