b. 84-103

composition: Op. 50 No. 2, Mazurka in A♭ major

2 slurs in A1 & GE

Continuous slur in FE

Slur in bar 103 in EE

..

The version of EE, featuring a slur in b. 103 only, most probably corresponds to the notation of the proof copy of FE, in which the engraver overlooked the slurs over the non-written-out fragment in A1 (b. 84-102). In turn, the continuous slur over all that section present in the finished FE results from proofreading, most probably Chopinesque. In the main text we give two slurs: in b. 84-87 and 87-103, featured both in A1 (interpreted correctly) and GE, since the version of FE, although the latest, was not a change of the thought-out phrasing of A1 and [A2], but an ad hoc correction of a serious mistake.

b. 86-90

composition: Op. 50 No. 2, Mazurka in A♭ major

No ornaments in A1 (→FEEE)

Mordents in GE

..

Just like in b. 11 and 15, it is uncertain whether the mordents in b. 86 and 90 were added by Chopin already in [A2] or only just in the proofreading of GE.

composition: Op. 50 No. 2, Mazurka in A♭ major

Just like in b. 12 and 20, in the main text we include the cautionary flats before a1 in b. 87 and 95, added in the first stage of proofreading of FE (→EE).
