First how did you know that it had to equal 2 full measures? I did not see how you arrived. Second please tell me is there any negative effect of moving the barline from score to staff I didn't want to do that on a global scale because this alignment is just one small section of a "normal" composition, but if it's safe? Then ok. Any caveats with moving to staff? Thank you. I don't understand the math of 2 full bars.In situations like these I might use the \scaleToLength function. That way it's possible to control the horizontal placement of the music in the different staves by judicious use of spacer rests and still not having to worry about getting the synchronisation points right between the staves. Also in that case there would be no need to use \cadenzaOn/\cadenzaOff.Hi Martin! How do you use the scaleToLength function? I can't find much about it when searching the documentation for it. Sounds interesting from how you describe it. Thanks! http://lilypond.org/doc/v2.19/Documentation/notation/index.htmlIt turns out I've forgotten I took it from this list some time ago (apparently written by Malte Meyn). It's basically just a wrapper for \scaleDurations but provides just the right interface for the mentioned use case. Before I used an own variation (because it's just that useful), but since it was written quite clumsily compared to Malte's, it just vanished into the mists of time... Anyway, here's the function: scaleToLength = #(define-music-function (dur mus) (ly:duration? ly:music?) (let* ((real-len (ly:music-length mus)) (mom (ly:duration-length dur)) (ratio-mom (ly:moment-div mom real-len)) (ratio (cons (ly:moment-main-numerator ratio-mom) (ly:moment-main-denominator ratio-mom)))) #{ \scaleDurations #ratio #mus #})) And using it is simple enough: \scaleToLength 1 { % some music } Try it, it's great! Martin, Thanks for the function! I'm still a little confused about the
value(s) that you use with the function. I see it looks like it
takes a duration value, right? Like 1, 4, 16? But I can't see how
it would work on the music. Maybe I just put the wrong example
music code in mine, but can you share an example where you input "
% some music " to show how the function works? Do you always use one number or does the function also allow/need like 1 4 or 1 8, etc. Thanks!
