Issues : Cautionary accidentals

b. 16

composition: Op. 25 No 11, Etude in A minor

..

Before the 1st semiquaver of the last group, GC and FE have no accidental, which, due to the fact that 11 previous notes in the R.H. (together with d1) were written on the bottom stave, is only an inaccuracy. GE1 added a  before this note. In turn, the absence of this sign in EE1 (→EE2) and GE2 (→GE3) is a mistake, as in these editions – same as in mUltimate Chopin – the entire part of the R.H. is written in this bar on the top stave.

GC (→GE1) and FE repeated the  before b, the 2nd semiquaver of the last group. The unnecessary in this context sign was removed in EE and GE2 (→GE3).

We add a  before fto two authentic cautionary naturals, before g1 and c2. The sign was added already in GE2 (→GE3), together with a few others: before c1b2 and the F-octave in the L.H.

Before the penultimate semiquaver, b2, GC (→GE1) has an unnecessary . The sign was removed in GE2 (→GE3) and added – most probably on the basis of GE1 – in EE3.

b. 61-62

composition: Op. 25 No 11, Etude in A minor

..

Chopin added cautionary naturals before in bar 61 and d1 in bar 62 in GC (→GE1); they were added in EE3 too). The second one of them was omitted in GE2, yet returned in GE3. The natural before f1 at the end of bar 61 is an addition, introduced most probably at the time of proofreading of FE. None of these signs are present in EE1 (→EE2).
All sources repeated  before g3 at the beginning of the 4th group of semiquavers in bar 61, while in GC (→GE) and EE also before g in the L.H. EE added also a  before the next g, most probably due to g3 in the R.H.
