The `\tweak positions` doesn't work which is kind-of expected.
However, for this very situation it would be nice if I could change
the start and end position of the slur manually.
Of course, it would be even better if LilyPond could handle this
situation automatically :-)
I have never encountered this scenario before, so I am quite curious.
What is the correct behavior? (I need to pick up a copy of Gould's
book, though that presumes she has addressed this.)
She has - on page 9.
I see at least three options:
- The tie should be sloped like a slur.
- The tie should be split into a two halves (possibly dotted/dashed),
each half attached to the terminal notes but individually still
horizontal to keep it distinct from a slur.
- The tie should be rendered as a \laissezVibrer and \repeatTie
combination.
Gould writes "Avoid changing a clef during a tied note, as the tie
will look cumbersome. If this cannot be avoided, the clef is best
changed at a system break". She gives three examples:
o "recommended" has the tie split across a system break at the same
vertical position, with the clef change delayed until after the second
part of the tied note.
o "acceptable" has the clef change at the system break, with each part
of the tie being horizontal and appropriately positioned to its note -
in different positions vertically, that is.
o "incorrect" has a tie winding its way from one vertical position to
another, in the process wrapping around the new clef sign.
See https://preview.tinyurl.com/tieClefChange (page 9).
Sounds like "acceptable" is close to my third option: use \laissezVibrer
and \repeatTie.
