In GC (→GE) Chopin wrote here a g note between f and a, increasing the number of the 1st group of demisemiquavers from 13 to 14. We give this version in the main text, being an expression of the latest proved decision of Chopin. However, the question whether it can be considered as the only final version of this run remains open. Chopin did not introduce it neither in the remaining two Stichvorlage manuscripts, nor in the proofreading of FE; it also cannot be found in any of the pupil's copies. Hence, the original thirteen-note version was accepted by him also after having introduced the correction in GC

The fingering of EE2 (→EE3) – see the adjacent note.

The fingering of both copies complements each other, hence in the main text we give it together. The fingering added by the reviser of EE2 (→EE3) is entirely compatible in this bar with the one following from Chopin indications. It also concerns the fingering of the first, thirteen-note group of demisemiquavers in EE – see a previous note in this bar.
