b. 1-4

composition: WN 37, Lento con gran espressione

in A1

No signs in CJ, CK (→CB) & EL

..

The short  marks suggest emphasising the dissonant chord. The former, reaching slightly further into b. 2, could be even interpreted as a reversed long accent. According to us, just like in the case of other complementary indications, these marks may be used in the version of the main text too.

b. 1-4

composition: WN 37, Lento con gran espressione

Repeated e1 in A1, CJ & CK

d1 in CB

Tied e1 in EL

..

The version of CB featuring d1 as the middle note of the first chord in b. 2 and 4 probably results from the fact that the note was placed too low in CK. In turn, the version of EL with tied e1 is probably an arbitrary change, introduced by Kolberg in the Stichvorlage for this edition.
