b. 80

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

..

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

b. 81

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

..

The figure filling the 3rd crotchet in the bar is composed of a semiquaver and 7 demisemiquavers, hence it creates an irregular group of an undefined structure. We preserve the vague notation of the sources, since it does not raise any doubts concerning the way of performing the figure and most probably it does not contain a mistake – it can be understood e.g. as a  or a .

Separate slurs in A (literal readingG→FEEE

Continuous slur in A, interpretation suggested by the editors

..

According to us, the slur of A in bar 82 is inaccurate (at the beginning of the page). The suggestion of a continuation of the slur in bar 81 is not particularly emphasised, yet taking into account the generally precise phrasing of A, leading the slur to the end of the phrase seems to be more likely.
