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.
