In A there are visible traces of a change of the bottom note in the 3rd chord in bars 5-6 (as well as in bars 13-14, which are marked in an abbreviated form in A as a repetition of bars 5-6). Originally, all the places featured c2, hence Chopin proceeded from the strictly analogous version to bars 1-2. Cf. bars 37-38.

At the beginning of bars 17, 19, 23 and 25 A includes  indications, while in bar 21 – . In the editions all  marks were omitted and instead of  there is . Due to the fact that all other dynamic indications in these bars were more or less accurately reproduced, it seems highly unlikely that the changes had not been accepted and partially introduced by Chopin. Therefore, in the main text we leave the version of FE (→GE,EE) without any additions. The version of A may be considered as an alternative one.
In bar 21 the erasure visible in A allows to conclude that originally Chopin most probably wrote there .

In bar 17 we add cautionary naturals before f1 and f2. In bar 19, in a similar situation, the signs are already included in A.

In bar 17 in A there is a visible trace after the change of the lower note of the 3rd chord in the R.H. from g1 to f1. Chopin introduced similar changes also in bars 19 and 21. Cf. bar 22.

In A there is a visible change of the inner note of the 5th chord in the R.H. – in bar 19 Chopin first wrote e2, which he then changed to f2, while in bar 21 he changed g2 to f2.

Between the 5th and 6th quavers in A one can see an unnaturally big gap and traces of deletion of something which had been written there. According to us, it could have been an originally envisaged additional chord, e.g., A-f-c1 in the L.H. and f1-c2-f2 in the R.H. It is striking that it does not seem that the deleted chord was supposed to be the last one in the bar, replaced then by another one – originally the bar included seven chords, the penultimate of which was eventually removed.
