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).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 3/4e8 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 2/4a4 cis | d d8 cisanother 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 2/4e4 e | f e | Could somebody explain a solution - but please very easy comprehensible :)
