Thanks, Knute. I missed the part about \shape that it can take multiple
sets of control points. Clearly I did not read that NR entry carefully
enough!
I am surprised to hear that Lilypond's default is standard in this case,
since I haven't found examples of this in published works, and I have
I think it is the slur that is lower, not the accidental that is
higher, and I think its placement is correct according to "convention"
(or Gould), but if you want to change the shape of a slur broken over
two systems, you can use the \shape command:
\version "2.22.1"
\include "english.ly"
When a tie on an accidental is split over two systems, Lilypond shows
the accidental on both notes (which I think is correct), but then
positions the tie on the second note very high, so as to clear the
accidental. This looks wrong, since ties are generally supposed to be
close to the note head,
