f in A

f in A

No note in GE (→FE,EE,FESB)

..

In the main text we include the f semibreve present in A. It also appears in all sources of the orchestral part (in violas), including in the later record of this bar in AsI. The absence of that note in the editions most probably resulted from a mistake by the engraver of GE1; perhaps he was uncertain where to put it – more or less in the middle of the bar, as in A, or at the beginning of bar as required by the general rule of vertical alignment of notes played simulaneously.
These variants do not apply to the original version of the opening eight-bar period, written in AsI.

Ornament in AsI

Grace notes before trill in A (→GE1EE)

Grace notes after trill in GE2 (→GE3,FESB)

Grace notes before & after in FE

..

According to the notation of AsI, the intended shape of the melody of this fragment always included the bottom second (b1), both in the introduction and the ending. Therefore, the fact that A (→GE1EE) does not include a written-out ending of the trill does not mean that Chopin intended a performance without an ending; it is simply an inaccurate notation. The changes introduced into GE2 and FE resulted from Chopin's intervention, whereas GE2 misinterpreted Chopin's indication, as a result of which the grace notes were encompassed with an octave sign and not added after the trill (as they should be).

Crotchets after minims in AsI

Crotchets after minims in A (→GEFESB)

Crotchets and minims together in FE & EE

..

Due to small gaps between the notes in GE1, the minims and the following dotted crotchets are written very close to each other; consequently, FE and EE interpreted it as a cue to combine the voices, which, in turn, led to the two notes being played simultaneously. In subsequent bars, a similar situation can be observed.

c in A, FE & GE2 (→GE3,FESB)

e in GE1 (→EE)

..

The version of GE1 (→EE) must be a Terzverschreibung, corrected in GE2 (→GE3,FESB) and in FE1, probably by Chopin.

e in A, FE, FESB & GE3

e in GE1 (→GE2,EE)

..

The version of GE1 (→GE2,EE), featuring e, is almost certainly erroneous – there are no traces of removal of the , despite the numerous traces of corrections visible in this and adjacent bars (very clear in GE2) related to the misinterpreted L.H.-part rhythm. The overlooked  was added by FE and FESB.
EE revised the version of GE1 by removing the  to e in the 2nd half of the bar, unnecessary due to the missing  at the beginning of the bar.
