It looks like \RemovesEmptyStaves and friends are what you are looking
for: This command removes staves which contain only rests from the score
so you can have two staves all the time but fill the verse of the lower
staff with rests. In LilyPond 2.18 you might need an extra \override.
The code below shows how the command is used.

\version "2.18.2"

\header {
  title = "How to hide empty staves"
}

melodyTop = \relative {
  \clef treble
  \key c \major
  \time 4/4
  c'8 d e f g a b4
  \break
  c8 b a g f e d4
  \break
  c d e f g a b c
  \break
  R1*2
}

melodyBottom = \relative {
  \clef bass
  \key c \major
  \time 4/4
  R1
  c'2 f,2
  R1*2
  c1 c2 c
}

lyricsTop = \lyricmode {
  do re mi fa so la ti
  do ti la so fa me re
  so -- lo so -- lo so -- lo so -- lo
}

lyricsBottom = \lyricmode {
  do fa
  bass so -- lo
}

\score {
  <<
\new Voice = "top" { \autoBeamOff \melodyTop }
\new Lyrics \lyricsto "top" \lyricsTop
\new Voice = "bottom" { \autoBeamOff \melodyBottom }
\new Lyrics \lyricsto "bottom" \lyricsBottom
%% might be easier:
%{
{ \autoBeamOff \melodyTop }
\addlyrics \lyricsTop
{ \autoBeamOff \melodyBottom }
\addlyrics \lyricsBottom
%}
  >>
  \layout {
\context {
  \Staff
  %% LilyPond 2.18
  %% removes empty staves (but not in the first line)
  \RemoveEmptyStaves
  %% removes empty staves in the first line
  \override VerticalAxisGroup.remove-first = ##t
  %% LilyPond 2.19
  %% removes empty staves everywhere;
  %% \RemoveEmptyStaves still exists in 2.19
  %\RemoveAllEmptyStaves
}
  }

How to merge two scores into one?

[Jeff Epstein]

I'm not understanding how to merge two scores into one. The song just 
continues, but it's a different section with a different voice configuration. 
The first section has a single voice, the second has two. The only way I can 
figure it out so far is to print out two scores. Is there a way to merge these 
into a single score, so the song continues on the same line? Thanks.

A couple of thoughts for you (sorry, I'm using absolute pitch in all my
examples below). From top to bottom in the original score, here's what I
see:

1. as' ( b' )
2. g' ~ g'
3. e!' ( g' )
4. cs' ( d' )

Personally, I think this is overkill with the slurs since you really only
need one from one chord to the next, two max (is this for piano?). Now that
I'm looking at it a little closer, I wonder what the purpose of the slur in
e'! ( g' ) is supposed to mean in the first place... You can't play it AND
the tie at the same time, unless it's indicating a finger exchange or
something like that. So, here's what I'd recommend:

1. If you MUST replicate the original, re-map the curves to include the
tie, then adjust shapes as necessary (I think the tie is all you may need
to adjust--maybe flip its direction to DOWN?):

  2 4

2. Re-notate the progression with two voices, and combine the tied g' into
a single note, like so:

  << { g'2. } \\ { 2 ( 4 ) } >>
OR
  << { 2 ( 4 ) } \\ { g'2. } >>

depending on which order appears better to you.

3. If the tie is superfluous, then

  2 ( 4 )

4. If the second g' is really supposed to be sustained, then I'd do #2 and
omit the g' from the second slurred chord:

  << { g'2. } \\ { 2 ( 4 } >>

If I had to choose one, I'd go with #3 or #4.

HTH,
Abraham

Hi,

setting spanner-id via \=... has still some shortcomings.

In _this_ and only this case I'd go for a complete stencil-rewrite,
tailored at mass (every bow starts/ends at same height.

\version "2.19.52"

myStil =
  #(lambda (grob)
(let* ((c-ps (ly:slur::calc-control-points grob))
   (thick 0.1)
   (angularity 0.5)
   (height (/ (ly:grob-property grob 'minimum-length) 10)))
   (ly:stencil-add
(make-bow-stencil
  (cons (+ (car (car c-ps)) 1) (- (cdr (car c-ps)) 0))
  (cons (- (car (fourth c-ps)) 1) (- (cdr (car c-ps)) 0))
  thick angularity height UP)
(make-bow-stencil
  (cons (+ (car (car c-ps)) 1) (- (cdr (car c-ps)) 1))
  (cons (- (car (fourth c-ps)) 1) (- (cdr (car c-ps)) 1))
  thick angularity height UP)
(make-bow-stencil
  (cons (+ (car (car c-ps)) 0) (- (cdr (car c-ps)) 2.4))
  (cons (- (car (fourth c-ps)) 1) (- (cdr (car c-ps)) 2.4))
  thick angularity height DOWN)
(make-bow-stencil
  (cons (+ (car (car c-ps)) 0) (- (cdr (car c-ps)) 3.7))
  (cons (- (car (fourth c-ps)) 1) (- (cdr (car c-ps)) 3.7))
  thick angularity height DOWN

mySlur =
\tweak minimum-length #10
\tweak direction #UP
\tweak stencil \myStil
\etc


\new Staff \relative c' {
2 -\mySlur (
4)
}


Hopefully someone comes up with a better idea.

Cheers,
  Harm

Re: MultiMeasureRest symbol spacing

[Jan-Peter Voigt]

Hi David,

thank you!
I am looking forward to receive this patch 2.19.5x. And I'd say 8 is a 
reasonable default value. But the key point is, it is overridable!

Hi David,

I do understand the concerns about this matter. Most instrumental parts
shouldn't have this problem, as the measures will be spaced well. And in
most cases spreaded church rests probably indicate bad spacing or
line-breaking.

But still - in my opinion - an option to set a maximum distance would serve
for cases I am facing right now, where long church rests are followed by one
measure of cues which indicate the end of a recitative and display the last
notes and words. You will not find such cues very often, but whenever I
prepare parts like that I receive thanks from the musicians. In the attached
image your patch prevents spreading the 6-measure-rest. Perhaps an optional
maximum would be acceptable.



It should.  In this case (I project that) you would do an override like this:

\override MultiMeasureRest.max-symbol-separation = 2

That would make 2 staff-spaces the effective distance in your example,
because obviously LilyPond would want to make the distance much
greater.

(In fact, with a value like 2, you'd probably get a uniform spacing
throughout the document, since it's probably rare that default spacing
would be less than that.)

Setting the value to something like 6 would allow the distance to vary
with shorter measures of different sizes, but would cap the spread to
6 so the rest would still be legible when spacing is loose.




OK, a new patch set is up.  It implements max-symbol-separation as
described above.

I've created a default max of 8.0 staff-spaces, so there is still some
variability in ordinary measures.  If somebody has a better number,
I'm all for it.  (In any case, it's easily overridden, and the default
value will be displayed on the IR page.)

Best,
David

Replicating chord slurs

[Joel C. Salomon]

Neighbors,

I’m trying to replicate the chord slurs in the attached image. This
shows the closest two versions I’ve managed (image also attached):

\version "2.19.54"
\language "english"

\score {
  \relative c' {
\time 3/4
2
4

2
4
  }
  \layout {}
}

The first has the right notes slurred together, but looks bad; the
second looks less bad, but still isn’t right. Can anyone suggest another
tweak I might try here?

OK, while we're at that, there's my "page-layout" package
(https://github.com/openlilylib/page-layout) that greatly simplifies
this process. You can specify an arbitrary number of break sets (line
breaks, page breaks, page turns) and name them (e.g. "a4paper"/"screen"
or "manuscript"/"original-edition" or whatever) to be easily chosen for
a given compilation.
Breaks are given as a simple list, and it even handles mid-measure
breaks by implicitly inserting the \bar "" commands.

Re: Which Linux distro for Lilypond

[Dr Nicholas Bailey]

Watch out for Debian. There isn't a Lilypond in Testing (Stretch) AFAIK. It's 
because they've removed the old scheme version. I develop in Testing in the 
hope that by the time I get around to releasing anything, it will be 
compatible with Stable :) Stable released rather infrequently, but I use it on 
our servers and it is very, well, *stable*.

It's easy to install the Stable lilypond debian package on a Testing Debian 
box, fortunately. Debian is my favourite distro: I've tried others but always 
returned. Shame about the scheme thing, but it will sort itself out sooner or 
later (if it hasn't already!). I guess the clue's in the distribution name: 
"Testing" ;)
