b. 19-24

composition: Op. 10 No 12, Etude in C minor

..

We give the slurring of the figures in the L.H. in the standardised version, despite the fact that a few slurs are slightly inaccurately written.

b. 20-23

composition: Op. 10 No 12, Etude in C minor

No slurs in A

Slur in FE (→GE,EE)

Our suggestion

..

The slur over the motif in the R.H. in bars 22-23 was probably added by Chopin at the time of proofreading FE (→GE,EE). According to us, the lack of a similar addition over the first motif is an inaccuracy of notation, hence in the main text we suggest a suitable addition.

composition: Op. 10 No 12, Etude in C minor

 in A

FE (→GE1GE2, →EE)

No sign in GE3 (→GE4)

..

The  hairpins, written in A in the 2nd half of the bar, were printed in FE – certainly by mistake – under the chord in the middle of the bar. The unnatural in this context detail was removed in GE3 (→GE4).
