Issues : Cautionary accidentals

b. 455

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

..

In A the only accidental before the 1st chord in the R.H. is the cautionary  before e2. From the musical point of view, the version with dwould be possible, yet a comparison with analogous bar 425 and a  of d3 added – probably by Chopin – already in GE1 (→FEEE, →GE2) prove Chopin's mistake. Chopin committed the same mistake in a similar context in bar 423.
In the main text we omit the unjustified  before e2.

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.

A features a cautionary  before ein the last triplet, yet the necessary  lowering d3 to dis missing. A flat was added already in GE1 (→FEEE, →GE2), however, no source removed the superfluous .

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

..

We preserve the cautionary  before ain the 2nd chord of the bar, due to a in the previous bar. However, Chopin most probably wrote it to cancel a2, used in the original version of the notation of the 1st chord. In the main text we also add a cautionary  before c

..

The cautionary  before e3 written in A (→GE1) is probably a remaining element of the original notation, in which the previous chord included e3. In FE (→EE) and GE2 the unnecessary sign was removed. EE added cautionary naturals before g1 and g2.
