b. 5

composition: Op. 10 No 3, Etude in E major

No marks in AI

Short accent in GE & EE, probable reading of A

Dot & accent in FE

Possible interpretation of A

In the sources, the indications concerning the e1 crotchet are unclear. The fact of shifting the accent in A to the right may be considered as an irrelevant inaccuracy of notation or a suggestion of the sign's length. The version of FE seems to be even more puzzling, especially given the fact that it was most probably corrected – over the stave, to the right of the note there are visible possible traces of deletion of the accent. It is also unclear why the staccato dot was not included neither in GE nor in EE.
In the main text we give a short accent over the note, which combines the most definite elements of the notation of the sources. Alternatively, due to the melodic context, we suggest a long accent here.

A (→FEGE1,EE) includes an erroneous A2-C tenth. It is a patent error of Chopin in the number of the ledger lines. The pitch of the note was corrected in GE2 (→GE3GE4GE5).

composition: Op. 25 No 1, Etude in A♭ major

No sign in AI, CDP & EE

Lack of the sign in EE may indicate distraction of the engraver, copyist (if it was a copy of A that was the base text to EE) or of Chopin himself, if it was another autograph that constituted the base text or if the dynamic signs were added by Chopin already after the copy had been prepared. Moreover, in EE there are no dynamic signs in bars 4-7.
Also in AI, the second four-bar section of the Etude is practically devoid of dynamic signs – the accent in bar 6 is the only indication of this type.
