In A (→GE1GE2,FE,EE) Chopin overlooked the  raising e1 to e1 in the alternative accompaniment chord, despite it being present in AsI. The accidental was then added only in FESB and GE3.

As in b. 184 and 188, none of the sources includes an accidental that would specify the sound of the mordent's top note. The prevailing key in b. 184-190, F major, requires the use of e, which we indicate in the main text with a natural.

In an earlier version of the insert illustrating the orchestral part – see the note below – neither Af nor A contain a  raising a to a. A respective accidental is in the 2nd violins in AsI and the orchestral parts. The mistake was corrected only intermediately – in a later version of this insert, added in the stage of proofreading FE1, there is an a1 provided with a .

In AsIAf and A (→GE1EE1EE2) there is no  lowering c2 to c2. Chopin's patent oversight was corrected by FE1, GE2 (→GE3,FESB) and EE3.

Neither AsI nor A (→GEFE1,EE,FESB) include an accidental to the 7th semiquaver. The F major chord underlying this place is, however, thanks to the C7 chords present directly both before and after it, temporarily the tonic, which requires the use of e2, and not e2. This conclusion is also supported by bar 285 – in the orchestral version of this phrase all sources contain e2(3). The mistake, patent in this context, was, however, corrected only in the stage of proofreading FE2, probably at Chopin's request.
