b. 17

composition: Op. 10 No 2, Etude in A minor

..

In CLI there are no naturals returning c2 and e2, nor the sharp raising g1 to g1. The second error – lack of the  before e2 – remained unnoticed also in FE (→GE1,EE2).

Crotchet in CLIFE (→GE,EE

Quaver and rest in Ap

..

In the version for publication – FE (→GE,EE) – Chopin left the original rhythmic value of the crotchet on the 3rd beat of the bar, not taking into account the reduction applied in Ap. Similarly in analogous bar 44, as well as in 25 and 31.

No slur in CLI & FE (→EE2)

Slur in Ap, FEcor & GE

Slur in EE3 (→EE4)

..

The slur over the chords is in Ap, Chopin wrote it also in FEcor, however in finished FE (→EE) the sign was omitted, probably due to an overlap of a few Chopin's entries in this place. It is unclear how the slur appeared in GE; probably it is an accurate revision of the editor, e.g., on the basis of comparison with bar 44 (see also the remark in the next bar). In EE3 (→EE4) the slur was added under the chords, which is certainly an arbitrary revision.

Probable long accent in Ap

Possible  in Ap

Long accent in FEcor

 in FE (→GE,EE

..

The undeniable long accent, written by Chopin in FEcor, was reproduced in FE (→GE,EE) as  hairpins. The sign in Ap, as many others in this manuscript, may be interpreted as a long accent or hairpins.

Our suggestion

..

Our proposal (long accent) constitutes a resultant of undeniable elements of two sources including independently written indications in this place – Ap and FE (→GE,EE). We do not consider , as in the version for printing Chopin significantly reduced the number of these signs, while the type of the accent was determined by us on the basis of an entry made by Chopin himself in Ap
