Hi Kieren,
It did work for this example, and although it required a little tweaking to be usable on the project I'm working with, you gave me the lead I needed to achieve the results. Thank you!
I paste the snippet below for future reference if someone finds this thread and is dealing with a similar situation:
\version "2.19.53"
\layout {
\context {
\Score
\remove Mark_engraver
\remove Staff_collecting_engraver
\override RehearsalMark.self-alignment-X = #LEFT
\override TextSpanner.to-barline = ##t
}
\context {
\Dynamics
\consists Mark_engraver
\consists Staff_collecting_engraver
\override RehearsalMark.padding = #2
\override TextSpanner.padding = #2
}
}
\score { <<
\new Dynamics {
\override TextSpanner.bound-details.left.text = \markup { \teeny { "align with" } }
s1 \startTextSpan |
s4 \stopTextSpan \mark "This" s2. |
}
\new Staff {
\relative c' {
c4 d e f |
g a'' b, c |
}
}
>> }
