b. 10-12

composition: Op. 10 No 12, Etude in C minor

 in A

FE (→GE,EE

..

In A  marks in bars 10 and 12 are written only on the 4th beat in the bar, on  marks. According to us, the way of their arrangement is a result of the already disappearing in Chopin's times convention of writing marks inside their scope of validity (and not at the beginning). This is how it was understood in FE (→GE,EE), in which the indications were moved before the octave motifs. This phenomenon also appears in bars 50-53 and 60-63, to an even greater extent.

b. 12

composition: Op. 10 No 12, Etude in C minor

in A, GE & EE4

in FE (→EE3)

..

A has as the 2nd note in the L.H., same as in the remaining analogous bars. However, the note is written a little bit too low, which probably resulted in its interpretation as in FE (→EE3). This almost patent error was corrected in GE and EE4.

In the main text we give pairs of   hairpins following similar figures in bar 10 and analog., as well as identical figures in bar 64. In A both bars 14 and 54, in which there are also no dynamic marks in the L.H., fall at the beginning of the line and before a pair of bars of different figuration contour and accent layout in the R.H., which could have distracted Chopin.
