What I've done is specify that each music section is to be two 
measures via a few means: "1*2", "\breve", and "\longa*1/2".  One 
system has no rest leading it at all, and the other two are very 
unusual lengths indeed.  Each section has only a fixed half note 
spacer rest at the end, so their lengths are all unique.


Note that since I removed \cadenzaOn, there will be a default bar line 
every measure, which we can see in the output.  But this proves that 
the alignment of notes is correctly scaled by \scaleToLength.



Aaron that isSO awesome! Thanks for explaining that. I'm going to be 
using that function a lot for sure. :)

Thank you. I don't understand the math of 2 full bars.

In situations like these I might use the \scaleToLength function. That

the different staves by judicious use of spacer rests and still not

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.html

It 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)

Also, unless there is more flexibility with score layout than I'm familiar
with, if you break things into multiple scores, each score must start on a
new line, as I don't think you can change mid-line from score to score.

For actual multi-stave scores, that is probably not at all a problem.

But if the parts are also organized this way, then each part will have to
have a line break before and after this cadenza.  Whereas typically for the
instruments resting during the cadenza (unless you are putting the cadenza
cue in each part) the cadenza measure would probably just a whole bar rest,
that occupies only part of a line, and has other content before and/or
after it.

I guess if this is an actual limitation, you coulduse the multi-score
approach for the actual score, and a single-score approach for parts.

I might approach this by seeing if it is possible to create a "meta" 
engraver that is able to delegate to another engraver and selectively 
remain "silent" over a specified range of time.  In this way, the 
\Score-level engravers could be active except for the cadenza section.  
And the \Staff-level engravers are only active during the cadenza.


The concept seems like it could work, but I do not know the underlying

This "must include/remove all engravers once and for all at the beginning of 
the score" has always seemed to me to be an unfortunate fundamental reality in 
Lilypond. With certain grobs (e.g., BarNumber), it’s easy enough to use \hide 
or \omit (and revert) to vary the engraver’s apparent *output*… but with other 
elements (e.g., Timing stuff, SystemStart stuff, etc.), it’s impossible (as far 
as I know) to do anything except what you’re suggesting above.

Would it be technically possible to add a \newEngraverSection — analogous to 
\newSpacingSection — which would allow a single contiguous score to have 
different engravers "active" in different sections?

This isn’t even yet at the level of "feature request": right now, I’m just

And I forgot, things like time signatures would need to be duplicated as

up opting to move the engravers to the \Staff level.

Thank you. I don't understand the math of 2 full bars.


The two measures was just an arbitrary choice.  You don't need to it to 
be precisely that; but for whatever amount you do decide on, all staves 
will need to agree with one another so things line up.

any specified bar lines be duplicated across the staves manually.  
Normally, it is sufficient for one staff to say something like \bar "||" 
and that will automatically propagate to the other staves.


It seems to be a recommended practice to prefer specifying elements like 
bar lines in a common, shared "\global" variable.  If you do this and 
reference the variable for each staff, then technically you are already 
specifying the bar lines on each staff.  The redundancy means that the 
score should work just fine with the engravers moved.


If it turns out to be unacceptable to move the engravers for the 
majority of your project, you could consider engraving this cadenza 
section as its own score which allows it to have an independent layout 
block.  This alternate strategy means subdividing your one score into 
multiple scores, so you would need to adjust things like measure 
numbering, indentation, and other spacing variables to get the final 
output to appear seamless.

The article I linked covers more than just meter, specifically it covers 
how to have independent bar lines.  You need to follow it to ensure that 
your bar lines do not "bleed" into the other staves.


See the following:

\paper { ragged-right = ##f }
\layout {
  \context { \Score
\remove "Timing_translator"
\remove "Default_bar_line_engraver"

\consists "Default_bar_line_engraver"
  }
}

\new Staff \relative c'' {

  < d e f >1\> r1\!\fermata \bar ":|."

  \cadenzaOn
  r1*3/4\fermata \bar ".|:"
  < d e f >1\> r1\!\fermata \bar ":|."
  s1*5/4 \bar "||"
} >>


Regarding the spacer rests (or actual rests if you wanted them to be 
printed), the beginning and ending rests must add up to the same total 
across all staves.  So, for the above example, we need the rests to be 
equivalent to two full measures.  In the first staff, scaling the 
leading rest by 5/4 requires a corresponding scaling of the final 
spacing rest to 3/4.  The middle staff is trivial, and the final staff 
is just the opposite of the first.

Hi Aaron thank you for that help. I don't like to use indepedant meters
however since this section I believe should be cadenza for easy input.
However, I add spacer rests like you said but it makes everything way wrong
too many repeats and breaks everything. I don't see what you mean to add.
Can you give one example of a pairing of spacer and r1* to move one repeat
barline successfully? Many thanks. My error image.  error.png

Since you are going to have bar lines that do not line up, you need to 
follow the advice in this post[1] by Urs.


Otherwise, it should be easy enough to change the relative duration of 
the leading rests using the scaling operator.  That is, "r1*2" or 
"r1*1/2".  You will need to have a corresponding spacer rest (with 
appropriate scaling) on each staff to compensate for the variable 
lengths at the start so that the final bar lines will line up.

Aleatoric Elements with barlines

[Reggie]

Please can someone show me in Lilypond how possibly can you adjust or change
the space before the first repeats in order to acheive the attached image? I
don't know if you move padding or add hidden to padding but I'm confused.
Thank you. My best effort
