Long accents in A (→FE)

Short accents in GE

Different accents in EE

The accents in the R.H. at the beginning of these bars, despite their unimpressive size, display a form which is characteristic rather of long accents. The marks in FE, and in bar 63 also in EE, may also be considered as long. In the remaining situations, we see short accents in the sources.

In A (→FE) there is no  lowering d2 to d2 in the 1st chord. A relevant accidental is also absent before the topmost note in the L.H. In GE and EE the flats were added, yet in EE3 only the one in the L.H. In the main text we remove the unnecessary  before d in the 2nd half of the bar, which appears in the sources.
