Slur in sources

No slur, our suggestion

..

As was the case with b. 4 and 23, in the main text we omit the additional slur being a part of the marking of the irregular group – cf. General Editorial Principles, p. 16.

b. 79

composition: Op. 28 No. 15, Prelude in D♭ major

..

A (→FCGE1) gives 9 as the number of notes in the irregular semiquaver group (instead of 10). The mistake was corrected in FE (→EE) and GE2.
See also bar 4.
