Issues : Errors of A

b. 12

composition: Op. 28 No. 15, Prelude in D♭ major

c1 in A (literal reading→FE,FCGE1)

c1 in EE, GE2 (→GE3), FED & FES

..

The version of A (→FE,FCGE1), without a  before the 3rd quaver in the bar, almost certainly resulted from Chopin's mistake, which is confirmed by the flats he wrote in FED and FES. In FC there is also no  before the 7th quaver, most probably due to an oversight, since in A the accidental is poorly visible due to the crossing-out showing through the page. Admittedly, both flats are visible on the photo of FC; however, they were added there much later by H. Scholtz, which explains the absence of the former in GE1 (the latter was added thanks to the  in the R.H.). The fact that those flats were added later is evidenced by their font (they are clearly bigger than the ones written by Fontana) and by the intensity of blackening, pointing to a pencil.

b. 12-13

composition: Op. 28 No. 16, Prelude in B♭ minor

..

In A (→FC,FE) there is no accidental before the 4th semiquaver in the 3rd group, which would result in f2, which is impossible in this context. The oversight of a cancelled alteration, frequently encountered in Chopin's music, was corrected in GE and EE.

b. 13-14

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

No tie in A

Tie in FE (→GE,EE)

..

Lack of the tie sustaining a in A is most probably a mistake, which is confirmed by the tie added by Chopin in a proofreading of FE (→GE,EE).

b. 13

composition: Op. 10 No 7, Etude in C major

..

In A there is no  lowering a1 to a1 in the L.H. and the  lowering e2 to eon the 9th semiquaver in the R.H. The comparison with 11 analogous bars proves Chopin's oversight. In FE (→GE,EE) the accidentals were added.

composition: Op. 26 No 1, Polonaise in C♯ minor

No repeat sign in A (literal reading)

Repetition in FE (→GE,EE)

..

The sign opening the repetition of bars 13-37, in A probably accidentally overlooked, was most probably added by Chopin in the proofreading of FE (→GE,EE). Cf. bar 54.
