The edge-height pair can be given a value with:
\once \override Staff.LigatureBracket.edge-height = #'(0 . +0.7)
but how can I change only one of the members of the pair, leaving the other one
as it is?
There are two options: Either use the \offset command (if you want to
add a number to one of the members) or \override before-line-breaking
(if you want to replace one of the members without depending on the
original value). Both options can be seen in the following code (have a
close look to the exact output for difference).
\version "2.19.80"
{
% this takes the original values and adds 0 to left and 3 to right
\once \offset edge-height #'(0 . 3) LigatureBracket
\[ c'1 d' \]
% this takes the originale value for left and sets 3 (not 3+original)
for right
\once \override LigatureBracket.before-line-breaking =
#(lambda (grob)
(let* ((orig-height (ly:grob-property grob 'edge-height))
(orig-left (car orig-height)))
(ly:grob-set-property! grob 'edge-height (cons orig-left 3))))
\[ c'1 d' \]
}
