Issues : Errors of A

composition: Op. 2, Variations, complete

h2 sustained in A (→GEFE,EE)

No prolongation in FESB

..

The b2 note, provided with a ten., is prolonged to a crotchet in A (→GEFE,EE). It seems to be Chopin's mistake, since such a long value would have to be held also at the beginning of the 2nd half of the bar, which would certainly be a mistake. To avoid doubts, we change it to a quaver, almost exactly corresponding to its actual length. The fact that FESB omitted that extension could have resulted from that erroneous notation, with which the engraver did not know what to do.

The version of A may be the inadvertently left original edition of this bar (or maybe even of bar 7). In any case, a proofreading of FE – despite a possible error in the 2nd half of the bar – does not leave any doubts concerning the final intention of the composer. The natural returning f, which in FE is only before the penultimate note of the bar, was moved before the 7th semiquaver in GE and EE, which may render Chopin's intention accurately.

The  returning g, without a doubt omitted in A by mistake, was added in a proofreading of FE (→GE,EE).

In A (→FE) there is no  raising f2 to f2 at the end of the bar. This patent oversight (cf. similar bar 7) was corrected in GE and EE.

composition: Op. 25 No 4, Etude in A minor

..

The second chord in the R.H. is a crotchet both in the upper and lower voices. Hence the lower voice has 9 quavers in this bar. The error resulted from hastily performed articulation corrections – Chopin would delete the staccato signs written inside the chords, which, in some cases, required rewriting the entire chord; omission of the quaver flag occurred exactly in the last rewritten chord.
