b. 1

composition: Op. 25 No 11, Etude in A minor

in GC, EE & GE2 (→GE3)

in FE & GE1

..

The use of the  time signature surprises only in GE1, as in FE the  indication was not used in the Etudes – contrary to the manuscripts – at all, both in Op. 25 and in Op. 10 and the Etude in F minor, Dbop. 36 No. 1 (cf. also the Impromptu in A major, Op. 29). In any case, the correctness and authenticity of the  time signature is undeniable towards the compatible version of GC and EE. The correct time signature was returned in GE2 (→GE3).

b. 46

composition: Op. 25 No 11, Etude in A minor

Quavers in GC (→GE)

Dotted rhythm in FE & EE

..

Based on the fact of writing the part of the L.H. under the semiquavers of the R.H., the equal quavers in GC (→GE) are a result of a mistake of the copyist who forgot to add the dot extending b and semiquaver beam.

Tied minim in GC, FE, EE & GE3

Dotted minim in GE1

Minim without tie in GE2 

..

It is hard to state how the erroneous version of GE1 occurred, as the e minim, held with a tie, lasts the same as the dotted minim, one can assume an attempt (failed) to rationalise Chopin's notation. In any case, the erroneous dot extending e was removed in GE2, yet the tie was not added, which happened only in GE3

Semiquaver in sources

Quaver suggested by the editors

..

In this context, Chopin notation, although inaccurate, may mean only the hold of the dnote. Therefore, in the main text we suggest specifying the notation by extending the semiquaver to the required value of a quaver. This type of notation is also to be encountered in other Chopin's pieces, e.g., in Allegro de Concert, Op. 46, bars 162-163.

composition: Op. 25 No 11, Etude in A minor

..

In GC the triplets in the R.H. have a quaver beam. This patent error was corrected in GE.
