None of the six necessary naturals lowering d2(1) to d2(1) are present in CJ and CK, which is a striking example of overlooked accidentals of a current key. This is even more of anomaly given that the first two R.H. naturals are written in A1. CB and EL contain the correct text.

The clear accent in CK allows us to consider the longer mark in CJ a long accent, which we give in the main text. In CB and EL the mark was reproduced as a short diminuendo hairpin. Cf. b. 26.

The manuscripts conveying the text of [A2] are pretty united on the range of the dynamic hairpins in these bars (A1 is devoid of such marks). The whole-bar marks of EL are an arbitrary decision of Kolberg or the engraver.

c1 in A1

e1 in CK (→CB) & EL

..

e1 in the version of CK (→CB) and EL must be Kolberg's mistake – in A1 one can see that the note was corrected from e1 to c1. The version with c1 is an unquestionable Chopinesque improvement – it alleviates the impression of A-e1 having been moved parallel to F-c1, which opens the next bar.

Except for  in b. 21, in this section (b. 21-31) A1 is devoid of all performance indications and dynamic markings. In the main text we reproduce the markings of [A2] – sotto voce in b. 25,  in b. 27,  in b. 29 and  in b. 30.
