b. 33

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

4 long accents in A (→FE)

in FC

4 longer  in GE

8 short accents in EE

..

The four marks in A are typical long accents, which, however, were reproduced fairly accurately only in FE. The marks in FC are slightly longer, whereas in GE they were adjusted to the length of an entire semiquaver group. In EE, as it was performed in the preceding bar, the marks were considered accents and were doubled (there are separate accents for the right and the left hands).

b. 34-41

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

sempre più animato - - - till bar 41 in A

sempre più animato - - - till bar 40 in FC

sempre più animato - - till bar 38 in FE (→EE)

sempre - più - animato in bars 34-36 in GE

..

The sempre più animato indication occupies over 2 bars (b. 35 is written in an abridged manner) in A (→FCGE); in FE (→EE) – one and a half. It matters only in the case of GE, in which the dashes marking the range of that indication were overlooked, and it is only in the version of that edition that we reproduce it in our transcription. In A and the sources based on it, the dashes were led to the end of the next line, which in A falls on b. 41, but in FC on b. 40, and in FE even earlier, i.e. on b. 38. Therefore, the shorter range is a patent mistake, both of the copyist and the engraver of FE, hence in the main text we reproduce the notation of A. According to us, however, it cannot be ruled out that a similar mistake was committed also by Chopin, since he wrote the last dash already beyond the bar line ending b. 41, and performing b. 42-45 sempre più animato seems to comply with the culminant nature of the ending of the Prelude.

Slur in A (→FCGE)

No slur in FE (→EE)

The absence of slur is an oversight by the engraver of FE (→EE).

In A (→FC) b. 35 and 39 are marked in an abridged manner – with / marks – as a repetition of b. 34 and 38.

  [] suggested by the editors

..

The absence of a  must be Chopin's oversight (this bar is written in A at the end of the line, which promotes inaccuracies). In the main text we suggest adding the mark analogously to the 1st half of the bar, since the authenticity of the  mark added in FC (→GE) and FE (→EE) at the end of the bar is questionable.
