In the main text we reproduce the dynamic hairpin strictly on the basis of A. In FE the signs were generally slightly extended, however, in the first five bars they can be considered to be compatible with A. In turn, the 
signs in bars 41-44 are clearly longer (of a similar length as in bars 33-37). In the remaining editions all signs were reproduced practically in the same length, generally corresponding to the entire quaver beam. In bar 38 and 39-40 the differences are more distinct; we discuss these bars separately.
In the previous manuscripts there are no signs of this kind (in the entire Waltz – cf. bar 1), there is also no accent in bar 39.
