In the main text we give the undoubtedly later version of the accompaniment written – with minor inaccuracies – in PE. The new shape of the accompaniment in this version was provided with slurs and the indication legato, probably by Chopin. The text of EF is a more precise notation of the earlier version, written in a partially draft form also in JC. In that last manuscript, it is three additional notes that draw attention; their meaning and relation to the remaining part of the notation is ambiguous. It could be, e.g., a draft of a new version of the bass line in this bar developed by Chopin.

The sources based on the earlier autograph have the ornaments written at the beginning of those bars as , while PE, based on the later autograph – as . In this context, Chopin often used those symbols interchangeably to determine a mordent. Cf. the remark concerning bar 24

JC has a  before a in the chord on the 3rd beat of the bar. In this harmonic context, the sign is unjustified.

The pedalling of EF, probably added by Fontana, is valid only in relation to the earlier version of the accompaniment written in JC and EF.

No slur in JC & PE

Slur in EF

..

The slur in EF – despite the fact that it corresponds to the natural phrasing – is probably an addition by Fontana. A similar reservation concerns the slur in bar 12.
