The notation of JC reflects the erroneous draft notation of [AI]. Formally, the notation of EF is correct, but lack of hold of the second f may be considered as an oversight in relation to the remaining sources (or perhaps as a revision – cf. bars 44-45). In the main text we give the more precise notation of [A] (→PE). category imprint: Interpretations within context; Differences between sources issues: Errors in Fontana's editions |

Holding the bass note with the hand (the so-called harmonic legato), a ploy often used by Chopin, is marked only in PE. category imprint: Differences between sources |

The sources differ in the details of the notation of "harmonic legato". In the previous version, the second semiquavers of the groups are extended to the value of a crotchet, except for the last group in bar 21, in which there is no relevant extension (see also the note related to bar 22). In the later version of PE, all those notes are dotted quavers. One could wonder whether Chopin changed here the performance (the second notes of each group were supposed to slightly overlap the next harmony in the previous version) or he just improved the notation, bearing in mind the same performance from the beginning (therefore, the original notation would be simpler, yet less precise). category imprint: Differences between sources issues: Errors in Fontana's editions |

The chromatic, homogenous progression of syncopations in JC and EF was divided into two motifs in PE, according to the flow of harmonic tensions. category imprint: Differences between sources |
