Quavers in GC (→GE) & EE

Crotchets in FE

..

In the main text we suggest quavers, as their authenticity is beyond any doubt. In turn, the crotchets in FE may be a result of the engraver's inattention – the spaces between the c-B and B-a notes correspond to the previous space c-c (quaver) and not G-d (crotchet), which probably means that the engraver planned the notes, seeing quavers in the base text, however, then he omitted this place while adding the beams. On the other hand, one cannot completely exclude Chopin's proofreading in FE – he may have accepted crotchets during the lessons, as an appropriate correction was not written in any of the three pupil's copies (two of them – FED and FES – bear clear traces of a detailed development of the Etude with Chopin, while in FES the first added fingering concerns exactly these two notes).

In GC and FE there is no  lowering c to c. This patent inaccuracy was corrected in GE and EE.

No sign in EE1 (→EE2)

..

In the main text we give the unambiguous  hairpins written in GC (→GE). The  sign in FE may be a result of a frequently encountered print error consisting in inserting the mirror-image of the intended sign (cf., e.g., the Etude in C minor, Op. 10 No. 12, bar 53). The absence of the sign in EE1 (→EE2) is most probably a result of inattention, while its addition in EE3 – a revision based on GE.

b. 24

composition: Op. 25 No 7, Etude in C♯ minor

..

In FE there are no accidentals before the 7th and 8th demisemiquavers. This frequent inaccuracy in Chopin notation was most probably repeated after the manuscript. Chopin partially corrected his mistake in GC and FED, adding a  raising g to g. EE and GE include the correct notation.

composition: Op. 25 No 7, Etude in C♯ minor

..

In FE there is no  lowering g2 to g2 on the 1st chord of the bar, which is a patent error. The sign is in all remaining sources. All sources, together with FE, include a  at this pitch before the chord on the 2nd beat of the bar. In the main text, we omit this unnecessary sign in this context.
