The 
mark entered into A clearly refers to the bottom stave; as such – despite its considerable length – it denotes a long accent, as the similar mark in bar 72 does. This is how we interpret this mark in the main text. In GE, the extension of the mark and its vague position between the staves changed its meaning, which is confirmed by the remaining editions, based on GE, in which it was assigned to the R.H., as a complement to the 
mark from the preceding bar.
