d2 in A (→GEEE), contextual interpretation & FE

c2 in IE

..

In A (→GEEE) there is no accidental to the top note of the penultimate fourth, which gives d2. The flat to d2 in the next quaver proves Chopin's patent mistake, yet it was only FE that added the necessary . In IE the erroneous GE version was revised by changing this note to c2, which is quite satisfying in terms of sound, yet certainly inauthentic.

b. 88

composition: (Op. 4), Sonata in C minor, Mvt I

..

In the main text we do not include the cautionary  added by GE (→FE,IE) to e1 in the last R.H. quaver. The accidental was left out by EE1, while in EE2 it was added to a1, probably by mistake.

It is uncertain whether  present in the editions instead of  entered into A resulted from a revision or from a mistake. The possible change could have been motivated by the desire to indicate which dynamics to use in the development, which starts here.
