In A the b and bsemiquavers were written as quavers. Chopin's mistake was corrected already in GE1 (→FEEE, →GE2).

composition: Op. 21, Concerto in F minor, Mvt II

..

In the editions the last note is written as a hemidemisemiquaver. Therefore, the group filling the 4th beat of the bar contains a fractional number of demisemiquavers – 8½ in GE1 and 9½ in FE (→EE), which must be regarded as a mistake. The engraver of GE1 probably shortened the last note, kind of "automatically" – cf. bar 41. The mistake was revised only in GE2, by reducing the value of the rest, which does not correspond to Chopin's original intention expressed in A. However, it could be that an additional beam was added in GE1 (→FEEE) upon inspiration from Chopin, whereas leaving the rest without any changes was merely an oversight. In that situation, the version of GE2 would be a rational correction of an inaccurately performed proofreading of GE1. Such a possibility would be indicated by the overlooked '9' digit, determining the number of demisemiquavers in the group. The above analysis of the rhythm of the roulade's ending is binding regardless of the versions of its earlier part – see the previous note in this bar.

Minim in A

Minims in GE3 (→GE4GE5)

Despite the fact that the correct text is actually undeniable, its correct notation in the sources appears only in GE3 (→GE4GE5). The notation of A is unclear in terms of division into voices (hands), which may have resulted in a rhythmic error of FE (→GE1GE2, →EE2EE3). In turn, at the time of adding minim stems in EE4, the G note was omitted.

At the end of the bar A has two semiquavers in the L.H., which is undoubtedly a mistake, corrected already in FE1 in all remaining editions.
