Chopin at least twice changed the harmonic sequence in bars 22-23. The provided interpretations of two versions of the 3rd crotchet in bar 22 and of the top note of the 1st crotchet in bar 23 are to some extent uncertain due to not having access to the original. In the earlier one, there are no naturals to the d notes, yet the intention of using them is unquestionable – As contains more deficiencies of this nature, e.g. in bars 23-24, in which there is not a single 
to the d(1) notes. The chord used in the earlier version was applied by Chopin in the repetition of this phrase in bar 30.
