Lento misterioso in CXI

..

A possible authenticity of the indications of CXI remains purely hypothetical – the only assumption can be a correction, visible in A, of the initial Lento indication.

Slur from to c1 in A

Slur from B1 to c1 in FC (→GE)

Slur from to B in FE (→EE)

..

In the main text we give the slur of FE (→EE), since the vast majority of subsequent slurs, present in a similar context, is led to the 1st quaver in the next bar in A – out of 13 slurs in b. 1-12 and 15, it is only the slurs in b. 1, 8 and 10 that end on the 6th quaver; two (in b. 6 and 9) are ambiguous. We consider all the above slurs to be inaccurate, since the differences in the range of slurs are not related to the structure of motifs, e.g. the shorter slurs in b. 1 and 8 are opposed by the longer ones in similar figures in b. 2 and 7. Moreover, in A one can see corrections – the slurs in b. 4-5 and 5-6 were being extended (in b. 3-4 probably too). Along with the crossed-out staccato dot at the beginning of b. 2, it may indicate that the concept of markings of those figures changed from  to . Consequently, the aforementioned shorter slurs would be uncorrected elements of the initial slurring.
The slur beginning from the 1st quaver is an inaccuracy of Fontana, repeated in the next three bars too.

b. 1-8

composition: Op. 28 No. 19, Prelude in E♭ major

..

In A one can see crossed-out three-quaver slurs running from the 2nd quaver of each triplet to the 1st quaver of the next one. One can assume that the crossing-out was related to the legato indication added at the beginning of the Prelude. At the beginning of the Etude in A Major, Op. 10 No. 10, we can see an evolution of notation that was perhaps going in a similar direction; in that Etude, Chopin removed the initial accents while proofreading the French edition.
