b. 10

Accent in AI

..

Similarly as in analogous bars 1-2, AI has here only an accent under f2 at the beginning of bar 10. Lack of the  sign in bar 10 in A (→GE1) seems to be an inaccuracy of notation, corrected – probably by Chopin – in GE1a (→GE2GE3). After including this correction, the dynamic hairpins correspond to the scheme of analogous bars 1-2, as well as to the signs in FE and EE. In the main text we give the  hairpins written in A and  added in GE1a.

The  hairpins in A are written inaccurately – at the right-hand end, their arms are of different length, hence in GE they reach up to the middle of the 3rd group of semiquavers. The beginning of the sign, at the end of bar 10, also seems to have been added too early, which is indicated by the  mark, contrary to it, added in bar 10 in a proofreading of GE2, as well as by the hairpins in FE and EE.

b. 11-12

composition: Op. 25 No 1, Etude in A♭ major

Two-bar long slur in AI, A (→GE) & FE

Two slurs in EE

..

The broken slur of EE may result from misunderstanding of the manuscript, perhaps inaccurate. In A, bar 11 closes the line; this layout, conducive to ambiguities in the slurs' notation, was probably repeated in the manuscripts which served as base texts for FE and EE.

No sign in AI, CDP & EE1 (→EE2)

The longer hairpins in A may have concerned the renounced by Chopin (deleted in A) version where he would raise the fifth of the chord only on the 4th beat of the bar. In the main text, we give the hairpins corrected by Chopin in GE1a (→GE2). The version of GE3 is a result of a revision returning the state before the proofreading of GE1a; the version was introduced also in EE3.

b. 13

composition: Op. 25 No 1, Etude in A♭ major

Accent in AI

 in A

 in GE, FE & EE

..

The type of accent used in AI may raise doubts. We interpret it as a long accent, as the sign is clearly bigger than the short accents in bars 6 and 10. In the final version, Chopin rejected the accent, choosing a pair of   signs in this and the next bar instead. In the main text we give the hairpins in a form being compatible with the notation of A to the greatest extent.
