Issues : Omission of current key accidentals

b. 17

composition: Op. 28 No. 8, Prelude in F♯ minor

b1 in sources, contextual interpretation

a1 suggested by the editors

..

In all sources, the 3rd demisemiquaver in the 2nd group is a b1 (literal interpretation). It is the initial uncorrected version, left by inadvertence – in A, initially, the 3rd demisemiquaver in the first two figures of each of b. 15-18 was a b1, which Chopin then changed to a1 in 7 out of 8 places. Such an oversight in correcting one of a few analogous places would happen to Chopin on a few occasions. The fact that he forgot the discussed note while performing corrections is also evidenced by it having been left without a , which was before the respective note of the 1st group of the bar in the initial version.

In A there are no naturals raising b to b and B to B. The accidentals were added both in FC (→GE) and FE (→EE).

In AR, AE and AG (→CY), Chopin did not write a natural raising d2 to d2, which is evident in this context.

Our variant suggestion

..

It is difficult to decide whether we are dealing here with one authentic version or with two authentic ones. FE1 has no accidentals in this bar, and such sloppy notation (naturals are obviously needed to lower d to d) suggests that also the  lowering G to G could have been omitted. On the other hand, it i s precisely this observation that could have inspired the reviser of GE to add a  in that place, so both  and G could possibly be the only authentic version. For that reason we decide to have a variant solution. 

In versions with the natural we add a cautionary  before g in the following bar.

composition: Op. 10 No 6, Etude in E♭ minor

..

In A (→FEGE1GE2GE3GE4) there is no  raising c1 to c1 in the chord at the beginning of the bar, which must be an error. Chopin added the necessary sign in FED (as well as the second one "on the run", unnecessary before in the 2nd half of the bar). The correct text is included also in EE and GE5.
