b. 1-2

composition: Op. 28 No. 6, Prelude in B minor

  in A (contextual interpretation→FC)

  in FE (→EE)

  in GE

No markings in CGS

..

The range of the  hairpin in b. 1 is difficult to determine in A – the top arm is much shorter than the bottom one. According to us, it is the range marked by the top arm, written first, that was intended by Chopin. It is compliant with dynamics, naturally resulting from the shape of the melodic line, and this is how it was reproduced by Fontana in FC (→GE). That interpretation is also supported by the range of the  hairpins in analog. b. 3 and 9 (as well as 23), in which the range of the top arm remains unchanged, unlike the considerable and rather accidental changeability of the bottom one. The differences in the length of the  mark in b. 2 seem to be inaccuracies (in FC, not affecting the meaning) or routine revisions (in editions).

CGS overlooked the vast majority of dynamic markings – except for two  in b. 13-14. According to us, it is an oversight of the copyist.

Similar problems and differences occur in following, similar bars 3-5, 9-11 and 23-24.

In A one can see that the initial tempo marking was Largo. Cf. changes of markings in adjacent Preludes.

A possible authenticity of the indications of CXI remains purely hypothetical – the only assumption can be a correction, visible in A, of the initial Lento indication.

In A the  mark is written before the bass E, which, due to the significant horizontal spaces between subsequent notes, does not contribute to misunderstandings – both in FC (→GE) and FE (→EE) it was placed under that note. In turn, in CGS a respective mark was placed not only before the note (like in A), but also before the bar line; moreover, the e1 crotchet in the upbeat falls precisely over that mark, which already changes the meaning of that indication. Such a pedalling would be perfectly acceptable; however, it is difficult to say whether the copyist conveyed here a pedalling variant, perhaps authentic, or whether she simply inaccurately wrote the version of FE. A  mark at the beginning of the piece (written already under the time signature) appears also in CXI.

In CGS the discussed  mark is the only pedalling indication in the entire piece. Therefore, it suggests another possible explanation for such a position – placed at the beginning of the piece, the mark is just a general indication, according to which the pedalling should be natural (=harmonic).

b. 1-4

composition: Op. 28 No. 8, Prelude in F♯ minor

..

In the figurations featuring the interval of an octave, Chopin would often be satisfied with an accidental placed only next to the first note constituting that interval (cf., e.g. the Etude in A Major, Op. 10 No. 10, b. 5-8 or the Ballade in F Major, Op. 38, b. 48). In the Prelude in F Minor, such an extended validity of accidentals is a strictly observed rule – accidentals are absent even in the places where they are necessary to cancel the previous alteration (e.g. on the 2nd demisemiquaver on the 3rd beat of b. 4), while in b. 8 Chopin actually crossed out the necessary accidental next to the 2nd demisemiquaver in the 3rd figure. In the discussed bars, apart from the situation in b. 4 mentioned above, the problem concerns the 8th demisemiquaver in the 3rd group in b. 1-2 and 4, the 8th demisemiquaver in the 1st, 2nd and 4th groups in b. 3 and the 2nd demisemiquaver on the 3rd beat of b. 3. Such a notation is to be found in A (→FC,FEEE1), whereas EE2, GE1 and GE2 added the majority of the necessary accidentals (5, 6 and 7 out of the eight necessary, respectively).
The L.H. quavers falling an octave lower than the first semiquaver of a given figure provided with an accidental are written down in a similar way, without the necessary accidentals – see b. 3-4.
