b. 37-38

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

Two slurs in AI & EE

Two slurs in A

One slur in CDP

Two slurs in FE & GE1

Two-bar slur in GE2 (→GE3)

..

In the main text, we give the most accurate, according to us, interpretation of slurs of A, given in GE1 and compatible with the notation of FE. It seems to be highly unlikely that Chopin would have liked to then withdraw from the concept of slurring written in A.

Particular sources differ quite significantly, as far as the range of  hairpins is concerned. Taking into consideration the fact that the notation of A is not very precise in this respect and the fact that the signs in the base texts for FE and EE could have been written also by Chopin himself, in the main text we suggest hairpins of an average length and placement. Similarly in analogous bar 39.

In AI one can see that, initially, it was the one octave lower Athat was the bass note at the beginning of the bar.

b. 39-47

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

..

The final section of the Etude, plenty of repeating figures, is written in all manuscripts – AI, A and CDP – with as frequent use of // repetition signs as possible. Same as before (cf., e.g., bar 19), we consider the notation of A in bars 41-43, which does not include the difference of size of the bass notes' heads, to be inaccurate.

It is hard to state which of the differently placed  marks of different length is closest to Chopin's intention (see the note to analogous bar 37). In this situation, in the main text we suggest – similarly as in that bar – a compromise solution.
