The slur in A (→GE1) ends one quaver earlier than in analogous bar 12. It is probably due to an imprecise notation. The slur was prolonged to c2 in GE2 (→GE3→GE4), a similar slur is also in EE. In FE the slur is not interrupted at all. category imprint: Graphic ambiguousness; Differences between sources issues: Inaccurate slurs in A |

The crescendo and diminuendo hairpins in bars 95-96 differ slightly in their range. In A the beginning of the dim. hairpins is written in a way which can suggest their beginning still in bar 95 – they are clearly extended in the new line. GE1 lacks the dynamic marks in bar 96. They were already completed in GE2 (→GE3→GE4). FE is lacking crescendo in bar 95, whereas EE is lacking diminuendo and crescendo in bar 96. category imprint: Differences between sources issues: Scope of dynamic hairpins |

The sources differ in the range of dynamic hairpins. In A Chopin wrote the hairpins from the beginning of the second triplet group and clearly led its ending under the penultimate quaver in the bar. It was reflected in GE2 (→GE3→GE4) and FE. In GE1 the hairpins were extended on the entire bar. In EE the beginning is concordant with A, while the ending was slightly shortened, to the 10th quaver. category imprint: Differences between sources issues: Scope of dynamic hairpins |
