b. 46

composition: WN 37, Lento con gran espressione

f in A1

in CJ, CK (→CB) & EL

..

The version of A1 must be earlier; taking into account the correction introduced in this autograph in analogous b. 5, one can assume that Chopin left it here by inadvertence. Anyway, [A2] must have included a here.

b. 48

composition: WN 37, Lento con gran espressione

..

The last note of the 1st semiquaver triplet is written in A1 as c3. This puzzling notation – later in the sequence, a respective note an octave lower is already written as d2 (without the necessary , which is a typical Chopinesque inaccuracy) – was initially also in b. 15, in which it was, however, changed by Chopin. Since all the sources coming from [A2] feature d3, we consider the presence of c3 to be an overlooked correction of one of the analogous places (a phenomenon known from many other pieces by Chopin), hence we reproduce this notation only in the graphic transcription of A1.

In the remaining sources the notation is enharmonically homogeneous, yet also inaccurate – none of the sources includes the  in the last triplet of the bar; in CJ and CK it is also the  lowering d3 to d3 that is missing, whereas in CB there are no naturals in this bar.
Similar inaccuracies concern the notation of e2 – in CJCK and EL there is no  before this note.

b. 52

composition: WN 37, Lento con gran espressione

..

In the initial version of A1 the last semiquaver group includes one note less than the version of the remaining sources coming from [A2]. Chopin initially omitted the target note of the run, e3; however, eventually he opted for a more homogeneous sequence consisting of seconds only. See the note on rhythm at the beginning of the bar.

b. 52

composition: WN 37, Lento con gran espressione

f in A1, possible reading

g in CJ, CK (→CB) & EL

..

The last L.H. quaver in A1 is written inaccurately – one can see it as f or g. In the main text we give g, which was most probably present in [A2] (→CJ,CKCB) and EL.

b. 52

composition: WN 37, Lento con gran espressione

..

Before the first semiquaver on the 4th beat, CJ has erroneously a  (b2) instead of  (b2).
