b. 39

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

..

In the main text, we give  according to A (→CDP,GE1; in the second German edition it was slightly moved). In the remaining sources, the indication was placed earlier, closer to the  sign.

b. 39-40

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

Two slurs in AI & EE

Two slurs in A

Incomplete slurring in CDP

Two slurs in FE

Two slurs in 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 (→GE2). It seems to be highly unlikely that Chopin would have liked to withdraw from the slurring concept, written in A.

In CDP, all phrasing slurs from bar 40 to the beginning of bar 48 were omitted.

Same as in bar 37, in the main text we give the later pedalling of A and editions.

b. 39-49

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

..

In CDP, there are no pedalling marks until the end of the Etude. We do not consider it a real "variant" of the indications and we do not include this source in the notes concerning pedalling.

b. 40

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

f2 in AI, A (→GE), FE & EE

e2 in CDP

The version of CDP is certainly a result of the copyist's inattention, who, looking for possibilities to accelerate copying with an abbreviated notation, did not notice the movement of the melodic line.
