b. 423

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

..

The cautionary natural before ein the 1st chord in the L.H. was added – probably by Chopin – in the last phase of proofreading of FE2 (it is absent in other sources).

The version of GE1 is certainly erroneous and it was corrected both in FE (→EE) and in GE2. In the main text we place a cautionary  before d2 and f1. The signs were added also in GE2.

b. 455-463

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

..

While proofreading FE (→EE), Chopin changed – just like in analogous bars 415 and 423 – d2 to e2 featured on the penultimate quaver in bars 455 and 463.

e3 in A (contextual interpretation) & FE2

e3 & e3 in EE

..

Just like in bars 422-423, the flats lowering e3 to e3 and the cautionary  before e2 in the L.H. in bar 463 prove that the version of A (→GEFE1), interpreted literally, is erroneous. In EE, a respective  is only in bar 463 (together with a  before e2), which is probably a result of an oversight of the sign in bar 462.

g2 in A (→GE)

d2 in FE (→EE)

..

Chopin hesitated about the pitch of the last quaver. It is already the crossings-out in A that prove that the decision was changed twice – Chopin started with g2, changed it to d2, to return to g2. GE features a g2, however, in the proofreading of FE (→EE), Chopin changed it again to d2. It is the latest version that we give in the main text; yet both versions may be considered to be equal. It is interesting that there are no traces of similar hesitations to be found in an analogous situation, as far as the sound is concerned, 4 bars earlier.
