Hi all,
I seem to be having trouble with rest alignment. The specific case I have is
pretty specific:
1. I have a multiple-voice section
2. I have /slurUp
3. I have a rest, with no rests before this point
In this case, the rest seems to still be high rather than centered, as if
another voice still existed. If there is a rest anywhere before the /slurUp
command, the problem does not exist. Is this a known issue or am I doing
something stupid?
\version "2.14.2"
{
% Problem here
<< { f' e' g' g' } \\ { e' d' d' d' }>> \slurUp d' r4
}
{
% This is fine
r4<< { e' g' g' } \\ { d' d' d' }>> \slurUp d' r4
}
{
% This is fine
<< { f' e' g' g' } \\ { e' d' d' d' }>> r4 \slurUp r4
}
This is one example of the problems that are related to the "A word of
warning" in the Learning Manual, Sect. 3.1.1 "Introduction to the
LilyPond file structure". If you explicitly tell LilyPond that you want
to create a voice of music, then the problem disappears:
\new Voice {
<< { f' e' g' g' } \\ { e' d' d' d' } >> \slurUp d' r4
}
What happens with the <<{...} \\ {...}>> construct is that LilyPond
creates two Voice contexts, called "1" and "2" and then goes back to the
main Voice that existed before the polyphonic part. However, if this
happens at the start of the score, then LilyPond has not had any
opportunity to create a main Voice context and then it keeps the "1"
Voice also for the following music. The simple solution is, as shown in
my example, to explicitly create a Voice context before the <<...\\...>>
section.
