b. 12

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

..

In GE3 (→GE4) the inner note of the 1st chord in the L.H. is a b. It must be a mistake.

b. 14-15

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

Slurs in A

Slur in FE (→GE,EE)

..

In A the bars are not written out, so we repeat here our interpretation of slurs in bars 6-7. The continuous slur in FE (→GE,EE) was probably included by Chopin while proofreading FE (cf. the second paragraph of the remark concerning bars 6-7).

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

a in chord in A

No a in FE (→GE,EE

..

Lack of a in the 1st chord in the editions is most probably a result of a mistake of the engraver of FE. Cf. bars 7 and 39.

b. 15-16

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

End of slur in A (interpretation), FE (→GE1)

EE & GE2 (→GE3GE4)

..

Neither A nor FE allow to determine whether Chopin wanted to lead the slur to the 1st quaver in bar 16 or not. The slur in bar 15 suggests a continuation both in A and FE (→GE1), yet in bar 16 – which in A is the first one written out after the shortcut including bars 10-15 and in the editions the first one in a new line – there is no slur in any of the sources. The first quavers in the bars in the 1st section of the Etude provided with a staccato mark are generally not connected to the pervious slurs, however, in subsequent sections longer slurs prevail. Therefore, in the main text we suggest a slur running to the beginning of bar 16, taking into account the fact that the slur in bar 15 in FE, clearly exceeding the last quaver, could have been written in this form by Chopin.

b. 16

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

End of slur in A & FE (→GE1), interpretation

No slur in EE & GE2 (→GE3GE4), literal reading of remaining sources

..

The ending of the slur from the previous bars, given in the main text, is a result of interpretation of unclear in this respect authentic sources, A and FE. When interpreted literally, the ending of the slur in this place is absent in both sources.
