Slurs

b. 8-11

composition: Op. 28 No. 16, Prelude in B♭ minor

..

In A one can see that Chopin would prolong certain L.H. slurs by adding to the slur the 4th quaver of three consecutive halves of bars, A, B and d, respectively. A similar situation can be found between b. 11 and 12.

b. 12-14

composition: Op. 28 No. 16, Prelude in B♭ minor

4 slurs in A (→FE,FCGE) & EE2

1 slur in EE1

..

The missing slur running from the last L.H. quaver in b. 12 and two subsequent ones in b. 13-14 in EE is a patent mistake of the engraver of that edition.
In FC the beginning of the first of those slurs is missing, which – at least theoretically – results in an ambiguity, as far as the presence or range of that slur is concerned, since the next bar is marked in the manuscripts in an abridged manner as a repetition of b. 12. We assume – like GE, based on FC – that the slur at the beginning of b. 13 is to be taken into account, in its full range, which means that it should also encompass the last quaver in b. 12.

b. 19-21

composition: Op. 28 No. 16, Prelude in B♭ minor

Single slurs in A (→FE,FCGE)

Double slurs in EE

..

Starting with the last quaver in bar 19, EE added additional slurs linking the pairs of the L.H. octaves. Similar arbitrary additions are not uncommon in Chopin's works published by Wessel. Similarly in the next bars.

Slur in bar 29 in FE

In the main text we give the two L.H. slurs beginning in the 2nd half of b. 29 after A. None of the remaining sources reproduced them faultlessly.
