Issues : Cautionary accidentals

b. 1

composition: Op. 24 No. 2, Mazurka in C major

..

At the beginning of the bar in A one can see a deleted  before e1. The need to put that sign could, in our opinion, result from the uninterrupted transition in writing - perhaps also performing - from the Mazurka in G minor  to the Mazurka in C major.

Before the last semiquaver in bar 1 FE (→EE2) has an undoubtedly authentic cautionary . The revisers of GE and EE3 (→EE4) added it also in bar 5. According to us, the signs in such a regular figuration are superfluous.

The cautionary accidentals before c1 in the L.H. were added in the L.H. in one of the last proofreadings of FE (→GE). They are also included in EE, apart from the  missed in bar 5 in EE2 (the engraver of EE also omitted  in bar 6, thus there are no accidentals on the entire stave of the 3rd great stave). This undoubtedly necessary addition probably comes from Chopin, although the signs are not to be found in any of the manuscripts.

In A (→FEEE,GE1GE2) there are naturals before the upper notes on the last semiquaver of each group (b1). The unjustified accidentals were removed in GE3 (→GE4). Cf. bars 4 and 12, as well as 37-39.

In AT, AW and CDP, there is no cautionary flat before the 4th crotchet (b). It may mean that Chopin added the sign in [A], at the time of preparing the Etude for print, shortly before giving [A] for copying.
