b. 18-24

composition: Op. 10 No 11, Etude in E♭ major

three times in A

three times in FE (→EE)

two times in GE

..

The missing dashes limiting the range of cresc. in bars 18-20 and 23-24 is a very common defect of the first editions of Chopin's works. Moreover, in GE there is no cresc. in bar 18, which also must be considered as a mistake.

b. 18

composition: Op. 10 No 11, Etude in E♭ major

..

The text does not raise any doubts here, yet the notation of accidentals differs in particular sources and it is not always precise. In FE the  before the 1st chord in the L.H. was initially placed at the pitch of c1 and it was probably at this stage that the copy constituted the base text for GE, in which the accidental was moved to the correct place (before g). In FE (→EE) the  before c1 was eventually changed to a , yet the necessary  before g was added only in EE. In GE2 (→GE3GE4) a  was added before c1, as well as before c2; the latter was also introduced in EE4. In A there is no flat before gin the 5th chord, which was already added in FE (→GE,EE).

b. 18-19

composition: Op. 10 No 11, Etude in E♭ major

..

In FE (→EE3) there is no ending of the slur in bar 19 (in the new line). It is a common mistake of the first editions of Chopin's works, particularly French, as well as of the autographs.

b. 19

composition: Op. 10 No 11, Etude in E♭ major

..

In A Chopin did not write arpeggio wavy lines next to the chords in the L.H. in the entire bar, which is certainly an oversight.

b. 19-21

composition: Op. 10 No 11, Etude in E♭ major

..

In A there is a visible change of the inner note of the 5th chord in the R.H. – in bar 19 Chopin first wrote e2, which he then changed to f2, while in bar 21 he changed g2 to f2.
