As was the case with the R.H. accents, we also reproduce the two marks in the L.H. part as long accents. The difference in the length of the marks between the right and the left hands in GE (→FE,IE) is noteworthy – the L.H. marks are much longer; they could be considered long accents. We reproduce them as diminuendo hairpins to illustrate the way these marks were understood by engravers – the difference in length corresponds to the gaps between notes, which in the case of L.H. crotchets are twice as big as in the case of R.H. quavers. This means that they were seen as diminuendoes referring to pairs of adjacent notes.
The absence of the marks in EE is probably due to an oversight.
