Issues : Uncertain slur continuation

b. 6-7

composition: Op. 28 No. 21, Prelude in B♭ major

..

In A the end of the L.H. slur in b. 6, which closes the line, clearly points to continuation, which is, however, absent in b. 7. In this case, it did not result in discrepancies in the remaining sources, since both FE (→EE) and FC (→GE) led the slur to the beginning of b. 7, undoubtedly in accordance with Chopin's intention.

b. 12-13

composition: Op. 28 No. 21, Prelude in B♭ major

No slur in FC (→GE)

..

In A, the slur starting in bar 12, last in line, indicates a continuation, but its ending is absent from bar 13. We adopt a natural contextual interpretation in accord with the FE (→EE) version. In FC (→GE), the copyist overlooked this slur like the previous one.

b. 33-36

5 slurs in A, literal reading

5 slurs in FC

3 slurs in FE (→EE)

2 slurs in GE

..

In the main text we give a contextual interpretation of the slurring of A – we consider the bottom slur in b. 33, which closes the line, to be inaccurate, since it is too short (like in a few other places, see b. 1). The clearly extended slurs in subsequent analogous bars undoubtedly reveal Chopin's intention. However, this notation was not reproduced correctly in any of the sources, which may be explained by revision (in all cases), an erroneous interpretation (FC) or carelessness (GE).

b. 38-39

composition: Op. 28 No. 21, Prelude in B♭ major

Slur to bar 39 in A, possible interpretation (→FE,FCGE)

Slur in bar 38 in A, contextual interpretation

No slur in EE

..

Bar 38 ends the line in A. Both the R.H. and L.H. slurs that begin in that bar clearly indicate that they should be continued. However, there is no trace of continuation of those slurs in b. 39; what is more, in the R.H. part the bar begins with a rest, which proves that the notation of A in b. 38 is inaccurate. Due to the above reason, in the main text we suggest an interpretation according to which the L.H. slur also encompasses only the 5 last quavers in that bar. Nevertheless, we can regard the interpretation of FC (→GE) and FE as equal.
