b. 8

composition: Op. 28 No. 18, Prelude in F minor

..

In A (→FE), Chopin wrote only a  restoring e2 (in the R.H. part). The corresponding sign in the L.H. part was added in FC (→GE) and EE.

b. 12

composition: Op. 28 No. 18, Prelude in F minor

..

In A (→FC,FE1) there are no accidentals before the last semiquaver (in both hands), which, when interpreted literally, gives d1 and d. In FE2 was added, yet only in the R.H., where it is a cautionary accidental. GE and EE include naturals in both hands.

b. 13-14

composition: Op. 28 No. 18, Prelude in F minor

New cresc. from bar 13 in A, literal reading

cresc. continued in bar 14 in FC (→GE)

cresc. continued in bar 13 in FE (→EE)

..

In the main text we reproduce the notation of A literally, in which cresc. in b. 13 somehow initiates a second wave of growth of dynamics. However, it is likely that Chopin meant it to continue the cresc. that began in b. 9, while its repetition in b. 13 was supposed to remind us what the dashes concern (b. 13 opens a new page in A). Therefore, the version of FE (→EE), in which this is how it was interpreted, may be considered an equal variant.

In A there is no  before the top note of the L.H. chord on the 4th beat of the bar. The patent inaccuracy was already corrected in FC (→GE) and FE (→EE).
