Fingering written into FESch, literal reading

Fingering written into FESch, contextual interpretation

No teaching fingering

..

In the main text we include the fingering entered into FESch, which could be coming from Chopin. The second and third digits are written inaccurately; we interpret them in accordance with the unequivocal entry in an analogous situation in b. 10.

Semiquavers in A (→FC,FEEE1)

Demisemiquavers in GE & EE2

..

Formally speaking, the version of GE is justified here; however, it is highly likely that Chopin wrote this group in semiquavers (like all the others) because he did not want to unnecessarily suggest a significant acceleration of movement. Such a notation is to be found in his pieces on a number of occasions – cf., e.g. the Prelude in D major no. 15, b. 4 and 79.
