In both bars there are no accidentals both before the 12th and the 13th semiquavers in A. The flats added in the proofreading of GE (→FE→EE) – almost certainly by Chopin – confirm that we are dealing here with a rare case of a fourfold composer's error, who overlooked both the naturals altering d2 to d2 and flats returning d2. Both necessary naturals were added in EE and the first of them (in bar 109) also in GE2. This kind of mistake may seem implausible, yet in the notation of A, in which the 2nd and 3rd groups of semiquavers are written an octave lower with the use of the octave sign, the error does not seem so striking:

GE has an additional note, c1, in the crotchet chord. The notation of A may be misleading here, yet Chopin's having deleted the note in the proofreading of FE (→EE1) is decisive. In EE2 (→EE3) the note was added under the influence of GE1. category imprint: Graphic ambiguousness; Differences between sources issues: EE revisions , Errors in GE , Authentic corrections of FE , Uncertain notes on ledger lines , Inaccuracies in A |

In A a before the bottom note of the octave in the L.H. at the beginning of the bar is missing, as well as before the 3rd semiquaver in the R.H. in the 2nd half of the bar (d1). In turn, Chopin repeated a before B, the 2nd semiquaver in the L.H. In GE1 (→FE) only the missing before the octave was added, while in EE and GE2 – both necessary naturals. Moreover, EE3 added a cautionary before b in the L.H. in the 3rd group of semiquavers; the sign was also added in FED. In the main text we add two necessary naturals and we remove the superfluous sign before the 2nd semiquaver in the L.H. category imprint: Interpretations within context; Differences between sources issues: Annotations in teaching copies , EE revisions , Annotations in FED , Accidentals in different octaves , GE revisions , Cautionary accidentals , Inaccuracies in A |

In A (→GE) a is missing before the 8th semiquaver in the L.H. (d1). In turn, Chopin repeated a before b1 in the L.H. at the end of the bar. FE removed the second sign, yet did not add the first one.

In A there is no accidental before the penultimate semiquaver. The flat returning e2 was added in the proofreading of GE1 (→FE→EE, →GE2), perhaps on Chopin's demand. Moreover, a cautionary was added before e1 in the L.H. category imprint: Interpretations within context; Differences between sources issues: Omissions to cancel alteration , Authentic corrections of GE |
