b. 45-46

composition: Op. 28 No. 16, Prelude in B♭ minor

 in A (literal reading→FE1)

 in A (contextual interpretation→FE2EE)

No marking in FC (→GE)

..

The  mark is placed in A between the pair of the final chords, hence the fact that FE1 assigned it to b. 46 is formally justified – markings are not retroactive. However, it seems much more likely that Chopin applied here the manner of writing indications within the scope of their range, and the mark is supposed to concern both chords, as it was performed in FE2 (→EE). Cf., e.g. the Concerto in E Minor, Op. 11, 1st mov., b. 16.

b. 46

composition: Op. 28 No. 16, Prelude in B♭ minor

 under grace note in A, contextual interpretation

under chord in FC (→GE) & FE (→EE)

..

The  mark in A occupies an uncommonly large space – from the octave at the end of b. 45 to the crotchet rest in b. 46. The pianistic sense – increasing the span of the final chord – requires that the  mark be placed under the grace note, which, however, was not performed in any of the remaining sources. In a similar situation in the ending of the Prelude No. 5 in D Major, Chopin wrote  clearly under the grace note.

b. 46

composition: Op. 28 No. 16, Prelude in B♭ minor

No sign in A (→FE,FCGE)

in EE

..

The omission of the  mark at the end of the Prelude is quite frequently encountered in Chopin's pieces and almost certainly not accidental – cf. the ending of the Prelude No. 7 in A Major. The mark added in EE is therefore certainly inauthentic and inconsistent with Chopin's intention.

in A (→FCGE) & EE2

Small quaver in FE

Small crotchet in EE1

..

Further simplified forms of the grace note in FE and EE1 must be mistakes of the engravers. The revision of EE2 was based on a comparison with GE1.
