The differences between the sources result from mistakes and inaccuracies of both the copyist and the engravers of FE and GE. However, the issues concerning the decipherment and the interpretation of A were caused by, e.g. a dense notation, without spaces between the staves – actually, in A there is no space for pedalling markings, added later, which resulted in them being placed inaccurately at times. The interpretation of A given in the main text corrects the position of the 
marks in b. 1-2 and 5 – according to us, in A they are placed before the notes they concern, i.e. A (cf. the markings in analogous figures in b. 3-4) or D. We also move the 
marks, which precede them, accordingly. See also b. 17 and 18-20.
