b. 3-4

b. 3

composition: Op. 10 No 7, Etude in C major

in A

No indication in FE (→GE,EE)

..

According to us, an accidental omission of cresc. in FE (→GE,EE) is the most plausible explanation in this case.

b. 3-6

composition: Op. 10 No 10, Etude in A♭ major

Minims in A (→FEGE,EE)

Crotchets suggested by the editors

..

The notation of e notes as minims, used by Chopin in bars 1-3 and 5-6, despite being formally incorrect in the case of the ones featured in the 2nd half of each of these bars, seems to be completely clear and it was not questioned. However, in bars 3 and 6 the 2nd minim means sustaining e also in the 1st half of bars 4 and 7, based on the B7 chord. Such a harmonic mix was rather not Chopin's aim. In A one can see that the minims were being added and probably the composer mechanically copied the notation, without considering the different harmonic situation. Due to this fact, in the main text we suggest to shorten the last e in bars 3 and 6 to a crotchet.

b. 3

composition: Op. 10 No 4, Etude in C♯ minor

No marks in AI & EE2

Uniform accents in FE (→GE)

Different accents in EE3 (→EE4)

..

EE2 omits accents, which was corrected in EE3 (→EE4), by changing the signs in the 2nd half of the bar for vertical accents.

The version of AI had to be also in [A], as the traces of its deletion are visible in FE. Similarly in bar 53, as well as in bars 11 and 61. The corrections visible in the discussed bar in AI prove that from the outset Chopin wavered as to the L.H. chords positions.
