composition: WN 55, Waltz in F minor

Acciaccatura in AO, AR, AE, AK, AG, CC

No grace note in F

..

All autographs include a short dgrace note. F does not have a grace note in this place - it results from a different ending of the melodic motif in bars 15 and 16.

In CX and CY, the grace note is not slashed - it may be a copying inaccuracy.

In AK, the natural next to the grace note was written clearly lower, in the 3rd space.
