⌂ Multi-measure rest markup
Markups attached to a multi-measure rest will be
centered above or below it. Long markups attached to multi-measure
rests do not cause the measure to expand. To expand a multi-measure
rest to fit the markup, use an empty chord with an attached markup
before the multi-measure rest.
Text attached to a spacer rest in this way is left-aligned to the
position where the note would be placed in the measure, but if the
measure length is determined by the length of the text, the text will
appear to be centered.
