b. 405

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

No c2 in chord in A (→GE)

c3 in chord in FE (→EE)

..

There is no doubt that it was Chopin that was the author of the correction introduced in the proofreading of FE (→EE). Chopin ended the Etude in F major, op. 10 no. 8 with an identical chord, also completed in the proofreading of FE.

b. 409-411

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

In A one can see a three-bar correction here: the text on the top stave, including the part of the R.H. and crotchets in the L.H. (two in each bar), was crossed out and rewritten on the staves above (R.H. part) and below (the crotchets in the L.H. together with the necessary changes of clefs). The reason for these changes was an imprecision following from the original layout of the text – formally, the octave sign over the part of the R.H. would also apply to the crotchets in the L.H. written below it, which, of course, was not intended by Chopin. The original crossed out notation does not include 8- - -, so Chopin noticed a possible inaccuracy only when proceeding to write an octave sign.
Therefore, one may ponder whether it was already [AI], on the basis of which the composer probably copied A, that contained an imprecise notation or whether it was Chopin that, in order to make the process of notation easier, changed the layout in a careless manner only when writing A

b. 413-415

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

..

In the main text we omit the cautionary naturals before eat the beginning of bars 413 and 415 and before ein bar 413. Although the change of key to F major was confirmed by the key signature, on a number of occasions, Chopin wrote unjustified naturals before e notes also later – cf. e.g. bars 424 or 428.

In the main text we add cautionary flats before bat the beginning of bars 414, 415, 422 and 423. In the first two bars, the signs are present in EE3. Chopin wrote a respective  in A in the last appearance of a similar situation, in bar 463.
