I want to have just 2-3 bars in a piece with different time for two voices.
In snippets I found
Changing time signatures inside a polymetric section using \scaleDurations
but I don't understand that very well.
Why doesn't lilypond just do what I write? it puts the first voice to 2/4 with
the second instead of remaining in 3/4:
one voice (and staff)
...
\bar "||"
\time 3/4
e8 a~ a gis c4 | r8 e, a4 gis8 c~ | c e, a8. gis16 c4 | e,8 a r16 gis c8 des a |
% other voice already in 2/4
gis8 d e4 e, | r2 r4
\bar "||"
% now all in 2/4
\time 2/4
a4 cis | d d8 cis
another voice (and staff)
...
\bar "||"
\time 3/4
r4 r8 c, f8. e16 | gis4 c,8 f~ f e | gis4 c,8 f r16 e gis8~ | gis c, f2
\bar "||"
% one voice still in 3/4
\time 2/4
e4 gis | a a8 gis | a c d f |
% now all in 2/4
e4 e | f e |
Could somebody explain a solution - but please very easy comprehensible :)
By default, LilyPond assumes that the music is normal, that is, that the
time signature is the same in all staves and that the duration of one
beat is the same in all staves. To change that, you have to tell
LilyPond to write separate time signatures for each stave and the
example you refer to shows how to do that. Also, LilyPond has to know if
a specific note in one stave should be typeset to the left or to the
right or below a certain note in the other stave (i.e. if it should be
played before, after or simultaneously). Therefore, LilyPond has to know
the mathematical relation between the beats in the different staves
(which is done using \scaleDurations).
Clearer?
