Hello Lilyponders!
I have a piece of music where measures have 4/4 time and 5/4 and it
looks
like this:
{
\time 4/4
c4 c c c
\time 5/4
c c c c c
\time 4/4
c c c c
\time 5/4
c c c c c
}
and the pattern goes on like that to the very end of piece.
I have a question: can I declare the alternating time signature on the
beginning of piece once so I don't have to declare it for every
measure? :
You could use a parallel voice that switches the time signatures using
\repeat unfold and a suitable count.
Another option is to use a compound meter. The only catch is that you
will not get a bar line between the 4/4 and 5/4, as the compound meter
treats each measure as the sum 4+5/4.
See the following for examples of both approaches:
%%%%
\version "2.19.82"
someMusic = \fixed c' {
| c2 d4 c f2 g4 f8 e d c
| g2 a4 g e8 f g a g2 e4
| f4 g a b g4 c' b c'2
}
\new Staff <<
{ \numericTimeSignature
\repeat unfold 3 { \time 4/4 s4*4 \time 5/4 s4*5 } }
{ \someMusic }
\new Staff { \compoundMeter #'((4 5 4)) \someMusic }
%%%%
