Issues : Inaccurate slurs in A

b. 4-5

composition: Op. 28 No. 17, Prelude in A♭ major

First slur to a1 in A, literal reading

First slur to end of bar 4 in FC (→GE)

Continuous slur to bar 10 in FE (→EE)

..

The range of the slur in b. 4 is unclear in A – it can be interpreted as a slur dragged to the a1 crotchet or as an unfinished slur/tenuto encompassing that crotchet along with the bottom voice quavers that fill it (as was reproduced by Fontana in FC). As it is slurs/tenutos that prevail in similar situations in the entire Prelude – particularly consistently from b. 65 on – in the main text we give such a slur. The continuous slur of FE (→EE), certainly contrary to the notation of A, probably resulted from the engraver's carelessness.

b. 87-88

composition: Op. 28 No. 17, Prelude in A♭ major

2 slurs in A (probable interpretation→FCGE)

Continuous slur in A (possible interpretation→FEEE)

..

The continuous slur in FE (→EE) resulted from the misleading notation of A, in which the ending of the slur in b. 87, which ends the page, goes far beyond the bar line, suggesting continuation. However, the slur in b. 88 clearly starts from the quaver (after the rest), and this is the slurring (more natural) that we give in the main text.
