b. 13

composition: WN 37, Lento con gran espressione

Slur under grace notes in A1

No slur in CJ, CK (→CB) & EL

..

Judging from the copies based on [A2], it did not feature the little slur under the group of grace notes. Therefore, we do not include it in the main text, since Chopin probably considered it superfluous.

Staccato dot in A1

No mark in CJ, CK (→CB) & EL

..

We do not include the staccato dot from A1 in the main text, since Chopin most probably did not repeat it in [A2], but wrote a slur, which is conveyed by CJ. The indications can be considered complementary; however, we take into account the fact that Chopin could have considered the dot to be superfluous after having put the slur.

b. 15

composition: WN 37, Lento con gran espressione

..

In A1 one can see a correction of the last semiquaver in the 1st half of the bar, which was initially written as c3. Chopin then crossed out the  and enlarged the notehead so that it reaches the line above and looks like d3. The original version is preserved in b. 48.

..

The compliance between CJ and CK allows us to believe that the  hairpin before the penultimate triplet reproduced the notation of [A2]. Nevertheless, in the main text we slightly extend this mark after analogous b. 48 – in this context, a diminuendo naturally leads us to the final note of the run, and the notation of the autograph could have been inaccurate. This idea was fully implemented in EL, most probably also on the basis of comparison with b. 48.
