b. 104-105

composition: Op. 22, Polonaise

Slur in FE (→GE)

No slur in EE

..

The missing slur is probably an oversight of the engraver of EE, although one cannot rule out that the slur was added in the penultimate stage of proofreading of FE.

b. 104

composition: Op. 50 No. 1, Mazurka in G major

No marking in A1

in FE (→EE) & GE

Our variant suggestion

..

The  mark is included in all editions except for A1. In such contexts, Chopin would often omit that mark at the end of a piece, and the editors would often add it. Therefore, we assume that the  asterisk may be inauthentic and we suggest a variant solution in the main text.

b. 104-106

composition: Op. 44, Polonaise in F♯ minor

Continuous slur in GE & FE2

Incomplete slur in FE1

Separate slurs in EE

..

In FE the slur at the end of b. 104, which ends the page, indicates that it should be continued in the next bar. It is confirmed by the slur of FE2 in b. 105-106 (in FE1 the page containing those bars is missing); however, in EE the slurs are separated here. A possible explanation for this discrepancy could have been an oversight of the slur in b. 105-106 in FE1 – the engraver of EE1 could have considered the ending of the slur in b. 104 (without a continuation) to be inaccurate and could have shortened it, whereas the reviser added a slur in b. 105-106 later on, adjusting it to the already printed preceding slur. For this reason, we retain the slur in FE1 unfinished in bars 105-106.

b. 104

composition: Op. 23, Ballade in G minor

..

FE (→GE1GE2) overlooked the  raising f1 to f1. The patent mistake of the engraver was corrected by EE, GE1a and GE3 (→GE4).

b. 104-109

composition: Op. 2, Variations, complete

..

In AsI Var. I is written as a draft, without almost any performance markings. In the discussed bars, the exception is the metronome marking provided at the beginning, =76. We do not comment on the lack of particular markings further on.
