b. 231-232

composition: Op. 21, Concerto in F minor, Mvt I

..

In A there are no naturals raising e2 to ein the middle of bar 231 and e1 to e1 two semiquavers later as well as e to at the end of bar 232. All signs were added already in GE1 (→FEEE, →GE2).

b. 231

composition: Op. 19, Bolero

..

In GE, there is no cautionary  before the bsemiquaver. The space between the notes confirms that in FE (→EE) it was added in the last phase of proofreading.

b. 231

composition: Op. 21, Concerto in F minor, Mvt III

..

In A there are no flats lowering g1 to g1 and g2 to g2. This patent inaccuracy was partially corrected already in GE1 (→FE), by adding the first of the overlooked flats. The correct text is in EE and GE2.

b. 231-232

composition: Op. 21, Concerto in F minor, Mvt III

Slur to f1 in A, FE (→EE) & GE2

Slur to c2 in GE1

..

Shortening of the slur in GE1 is certainly an inaccuracy stemming from the transition into a new line. The inaccuracy was corrected both in FE (→EE) and in GE2. In the case of FE, Chopin's proofreading cannot be ruled out.
