Thank you for this code. Trying it out, I see that there is something
here I have not got understood. This MWE should explain all - I was
hoping that the text "Interlude" would appear centered between the two
systems, but its position still depends on the staff size:
8><8><8><8><8><8><8><8><8><8><8><8><8><8><8><8><8><8><8><8><8><8><8><
\version "2.24"
staffspaceinmm = #(ly:output-def-lookup $defaultpaper 'staff-space)
#(set-default-paper-size "a4")
%#(set-global-staff-size 10)
#(set-global-staff-size 18)
\layout { indent = 0 }
{
\repeat unfold #40 c'2
\break \mark \markup { \override #`(line-width . ,(/ 175 staffspaceinmm))
\fill-line { " " \lower #10 "Interlude" " " } }
\repeat unfold #40 c'2
}
8><8><8><8><8><8><8><8><8><8><8><8><8><8><8><8><8><8><8><8><8><8><8><
This centers "Interlude" with the global staff size set to 18 but not
10.
Thanks again
