b. 2-11

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

No marks in AI

Dots in FE (→GE,EE)

..

In AI, the staccato articulation of the quavers, separated with rests, accompanying the semiquaver figuration (in bars 1-3, 5-6, 9-11), is marked only in bars 1 and 5. There is no doubt that the dots written there are to be understood as a model, hence valid also in the remaining bars.

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.

b. 3

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

in AI

in FE (→GE,EE)

..

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.

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

b. 3

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

No sign in AI & FE (→EE2EE3)

Arpeggio sign in GE & EE4

..

Lack of the arpeggio mark in FE (→EE2EE3) may be explained with the correction of the part of the L.H., performed by Chopin in FE1 (see the adjacent note). Chopin, involved in changes in the structure and content of the chords, probably did not think of careful indication of their performance, considering arpeggios of such a broad chord to be obvious. Similarly in bars 11, 53 and 61.
