b. 41

composition: Op. 12, Variations in B♭ major

..

Two kinds of staccato markings present in FE (→EE), wedges and dots, very typical of Chopin in that period, were reduced by GE to one kind in the entire Variations – dots. This is what occurred in this bar: the wedge under the d1-f1 third in FE (→EE) was changed to a staccato dot in GE.

b. 49

composition: Op. 12, Variations in B♭ major

..

The f1 note at the beginning of the bar is a dotted crotchet in FE. This augmentation dot is practically meaningless, since f1 is repeated on the 3rd quaver. Therefore, it is probably a mistake or a trace of the initial version, without repeating f1 on the 3rd quaver. In this situation, in the main text we include the change introduced by GE and EE, in which the dot was omitted.

In FE the  raising e2 to e2 is missing. The patent mistake – e2 is featured in the opera's original theme – was corrected both in GE and EE.

b. 50

composition: Op. 12, Variations in B♭ major

..

In FE (→GE) we can see here "zf", which we change to the correct , as it was done in EE. The issue of the Chopinesque notation of forzato and its variants appearing in the sources is discussed in detail in the note in bar 1.

b. 54-55

composition: Op. 12, Variations in B♭ major

..

In FE in bar 54 and 55 the augmentation dots to the L.H. f minims are missing. It must be an oversight, in GE corrected only in bar 55, while in EE in both bars. Moreover, in GE the augmentation dot to the e1 crotchet in bar 54 was overlooked. We comprehensively discuss all irregularities concerning the rhythmic notation and the issue of division into parts in this fragment of the Variations in the note in bar 39.
