Fingering in EE

..

According to his generally observed rule, Chopin did not give here the fingering in FE, as he had already indicated it in identical figures in bars 1-10. In EE Fontana added the fingering after his own development of fingering in bars 5-10, yet not identical (the 2nd finger in the L.H. at the end of bar 47 is an alternative solution, while the 4th finger on d1 in bar 49 is certainly a mistake related to the change of fingering indications to the English system – General Editorial Principlesp. 10). In the main text we respect Chopin's decision expressed in FE of not repeating the fingering given at the beginning of the Etude

Slurs in A

L.H. slur in FE (→GE)

Slurs in EE

..

In the main text we give the slurs in the parts of both hands, as Chopin wrote it in A; such slurs are included in EE. We consider the fact that in A the slur in the L.H. begins two notes later than the slur in the R.H. as the notation's inaccuracy. In FE (→GE) the range of the slur in the L.H. is correct, yet the slur in the R.H. was omitted.

Our suggestion

..

We suggest to mark the bass note with a wedge after the chord in the R.H. The need for unified articulation in this context is undeniable.

b. 47

composition: Op. 10 No 12, Etude in C minor

..

In A (→FEGE,EE) the naturals before B1 and in the 2nd half of the bar are repeated. We omit these unnecessary accidentals. Before the next semiquaver in A there is no cautionary  (added in the editions).
