Brilliant, Harm! I figured I just wasn't understanding the mechanism
correctly. Now a similar function is easily created to do the custom
termination:
myStopTextSpan = #(define-music-function (mus) (ly:music?)
(ly:music-set-property! mus 'articulations
(cons #{ \stopTextSpan #}
(ly:music-property mus 'articulations)))
#{
#mus
<>^\markup \italic "a tempo"
#})
to get
\relative c' {
\myStartTextSpan b'1
\myStopTextSpan c1
d1
}
Thanks for the explanation and a usable solution!
Best,
Abraham
