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.

In A1  is the only performance indication in this and the next bars until  in b. 57 (except for a few R.H. slurs in b. 52-54). It cannot be ruled out that it could have been influenced by the layout – b. 49-56 fill one line of A1 and both the previous and the next lines abound in such indications. The missing top part of the second  mark makes the interpretation of this marking unobvious; it could also be . A very characteristic horizontal line, common for both letters (cf., e.g. four  on the 1st page of in the Scherzo in B Minor, Op. 31) is an argument in favour of .
In the main text we give the mark of the later version.
