Hoofdstuk 4: Tweaking output 115
Slurs by default are classed as within-staff objects, but they often appear above the staff if
the notes to which they are attached are high on the staff. This can push outside-staff objects
such as articulations too high, as the slur will be placed first. The avoid-slur property of the
articulation can be set to 'inside to bring the articulation inside the slur, but the avoid-slur
property is effective only if the outside-staff-priority is also set to #f. Alternatively, the
outside-staff-priority of the slur can be set to a numerical value to cause it to be placed
along with other outside-staff objects according to that value. Here’s an example showing the
effect of the two methods:
c4( c^\markup { \tiny \sharp } d4.) c8 |
c4(
\once \override TextScript.avoid-slur = #'inside
\once \override TextScript.outside-staff-priority = ##f
c4^\markup { \tiny \sharp } d4.) c8 |
\once \override Slur.outside-staff-priority = #500
c4( c^\markup { \tiny \sharp } d4.) c8 |
Changing the outside-staff-priority can also be used to control the vertical placement
of individual objects, although the results may not always be desirable. Suppose we would like
“Text3” to be placed above “Text4” in the example under Automatic behavior, above (see
Sectie 4.4.1 [Automatic behavior], pagina 108). All we need to do is to look up the priority of
TextScript in the IR or in the tables above, and increase the priority of “Text3” to a higher
value:
c2^"Text1"
c2^"Text2" |
\once \override TextScript.outside-staff-priority = #500
c2^"Text3"
c2^"Text4" |
Text3
Text2
Text1 Text4
This certainly lifts “Text3” above “Text4” but it also lifts it above “Text2”, and “Text4”
now drops down. Perhaps this is not so good. What we would really like to do is to position all
the annotation at the same distance above the staff. To do this, we clearly will need to space the
notes out horizontally to make more room for the text. This is done using the textLengthOn
command.
The \textLengthOn command
By default, text produced by markup takes up no horizontal space as far as laying out the
music is concerned. The \textLengthOn command reverses this behavior, causing the notes to
be spaced out as far as is necessary to accommodate the text:
\textLengthOn % Cause notes to space out to accommodate text
c2^"Text1"
c2^"Text2" |
