How do you change the shape of a tie that's in a chord? In the following example, neither \shape command has any effect.
%%%
\version "2.24.4"
tieShapeA = \shape #'((0 . 0) (0 . -1) (0 . -1) (0 . 0)) \etc
tieShapeB = \shape #'((0 . 0) (0 . -1) (0 . -1) (0 . 0)) Tie
\relative {
<c'~ g' -\tieShapeA ~ c~>4 q2.
<c~ \single \tieShapeB g'~ c~>4 q2.
}
