I see, I misunderstood. More like the opposite approach to LilyPonds glossary
then.

Re: A help document i would like to have

[TaoCG]

There is a music glossary as part of the LilyPond references which, I
believe, is what you're looking for, though many entries are incomplete yet.

Please, always post a minimial working example and the LilyPond version
you're using. Also the second image doesn't show for me.
Now I have to guess your problem and my guess is that you didn't connect the
notes with \glissando. The line won't print automatically after a staff
change.

Re: how to force extra accidental in this case

[TaoCG]

You could do it by changing the accidental style in your spacer voice.

\version "2.18.2"

Uppernotes = { \repeat "unfold" 8 { cis'8 } }

accidentals = {
s2
\accidentalStyle Staff.dodecaphonic
s8
\accidentalStyle Staff.default
s4.
} % doesn't work


LowerMusic = { r2 c'!8 r r4 }

UpperMusic = { \context Voice << { \Uppernotes } {\accidentals } >> }


\score {

\new PianoStaff

<<

\new Staff \UpperMusic

\new Staff \LowerMusic

There must be something wrong on your side. I can see a clear difference
between Regular and Medium in both normal and italic shape.
Well, I installed the Ubuntu fonts and tried to access the Medium face from
within LilyPond without success. Version is 2.18.2 on Windows.
Since the second post stated that it worked in 2.19.13 I supposed it might
have to do with the recent changes in font selection but apparently this
really is a bug which has been there before.

Does this work?

I don't have 2.19.14 installed but afaik the code for setting the global

Re: Ignore key signature?

[TaoCG]

You can also define your own accidental-style. The code below always prints
accidentals when a pitch has an alteration.
I suppose it will work the same for 2.19.

\version "2.18.2"

\relative {
#(set-accidentals-properties #f
 `(Staff
   ,(lambda (c p bn mp)
(if (= 0 (ly:pitch-alteration p))
'(#f . #f)
'(#f . #t

 'Staff)

\omit Staff.KeySignature

Re: lilypond-book and includes

Ok, I solved it. It's still strange though.
The problem lay in the included file at this part:

drumPitchNames =
#'((enuopen . enuopen)
   (enumuff . enumuff)
   (chacha . chacha)
   (en . enuopen)
   (em . enumuff)
   (ch . chacha)) 

When I rename the 'em'-shortcut to 'ef' it works.

Re: lilypond-book and includes

[TaoCG]

Thanks, I tried the mentioned workaround but apparently this isn't the
problem.
Its not that the included file is not found. As I said, if I specify a
non-existant file with \include while using --include I get an error that
file is not found, but when I put the correct filename I get an empty staff
instead of the desired output.

The file I want to include contains some custom drum-definitions.
I post it, maybe someone can try to reproduce the problem.

### file to include: bata-def.ly ###
#(define (place-rests rest)
 (let* ((sp 0))
 (if
  (eq? (ly:grob-property-data rest 'duration-log) 1)
  (set! sp -2))
 sp))

drumPitchNames =
#'((enuopen . enuopen)
   (enumuff . enumuff)
   (chacha . chacha)
   (en . enuopen)
   (em . enumuff)
   (ch . chacha))

#(define bata-style
 '(
  (enuopen () #f -2)
  (enumuff cross #f -2)
  (chacha () #f 2)))

\layout {
\context {
\DrumStaff
\name BataStaff
drumStyleTable = #(alist->hash-table bata-style)
\override StaffSymbol.line-positions = #'(-2 2)
\override Rest.staff-position = #place-rests
\override TimeSignature.style = #'numbered
\override Stem.direction = #1
}
\context {
\StaffGroup
\accepts BataStaff
}
}


### actual snippet ###
\include "bata-def.ly"

okonkolo = \drummode {
eo2 ch
}

\score {
\new StaffGroup
<<
\time 4/4
\new BataStaff \okonkolo
>>
}

lilypond-book and includes

[TaoCG]

Dear List,

I'm having trouble using includes with lilypond-book.
When I use \include in the snippet with an absolute path it works but when I
try to include the path with the comand-line option I get an empty staff.

e.g.

\include "/home/user/lily/test.ly"

works, whereas

\include "test.ly"

with

--include=/home/user/lily/

doesn't.

And I don't get an error message, it's just an empty staff.
If I change the \include to a non-existant file I do get an error message.

I use lilypond-book from within lyx if this matters.

So, using absolute paths would be a workaround but I'd much prefer finding a
solution for this to work with --include

Hi,

as Paul Morris pointed out \displayMusic is the best starting point to learn
the scheme way of writing music.
For example \displayMusic { c8[ c c c] } will show you how to beam a group.
Also I don't really get your last point. What kind of override do you want
to apply to the notes?

Regards,
Tao

Temporary polyphony with lyrics

[TaoCG]

Hey all,

I have a one-staff vocal part where I need somewhere in the middle a
temporary two-voice part withe different lyrics to each voice but my
attempts so far have failed and I have the feeling that I'm trying to solve
this the wrong way.
I prepared a minimal example and what strikes me as odd is that after the
temporary polyphony all notes are registered on the same time as if duration
wasn't important anymore.
I also tried \set associatedVoice with named voices instead of \addlyrics
but then the lyrics simply won't show.

\version "2.18.0"

foo = \relative
{
\voiceOne
c'1
}
\addlyrics { foo }

barr = \relative
{
\voiceTwo
c''1
}
\addlyrics { bar }

music = \relative
{
c'1
<< \foo \\ \barr >>
c1 c2
}

text = \lyricmode
{
text here
}

\score
{
<<
\new Staff \new Voice = "v" \music
\new Lyrics \lyricsto "v" \text
>>
}

Maybe something like this will work for you?
Since this separates text and music you'll have to count to place the text
at the right position.

\version "2.18.0"

Hi,

you can prepend your percent repeats with this:

s1*0^\markup "text"

I think this should give you the output you're looking for.

Hmm... I tried replacing the python3-directory with the lily\usr\bin\ and
now I get this error:

  File "C:\Program Files (x86)\LilyPond\usr\bin\musicxml2ly.py", line 2105
if current_staff and staff <> current_staff and not
n.get_maybe_exist_named_child ('chord'):
^
SyntaxError: invalid syntax


These brackets sure look strange. Is this an error in musicxml2ly?

I wrote an alternative approach to automatic octaves a little while ago.
Maybe it's useful to you:
http://pastebin.com/u9dbkENA

It uses capital notenames to add octaves.
For example

c4 D e F

is the same as

c4  e 

If you don't use the default pitch-language you have to modify the code to
suit your needs.
It's not extensively tested nor is it tested with 2.18 but I guess it should
work.

Regards,
Tao

musicxml2ly on Windows

[TaoCG]

Dear all,

what would be the best way to invoke musicxml2ly on Windows when there is
also a Python 3 installation.
When I try to run it with the python that comes with lilypond like this

python.exe musicxml2ly.py test.xml

I get this error:
Could not find platform independent libraries 
Could not find platform dependent libraries 
Consider setting $PYTHONHOME to [:]
'import site' failed; use -v for traceback
Traceback (most recent call last):
  File "musicxml2ly.py", line 3, in ?
import optparse
ImportError: No module named optparse

This is with Lilypond 2.16

Tao

I don't know exactly what happens in your example but a lyrics context
inside a voice doesn't seem right to me. Instead create a subvoice and
assign the lyrics later to it.
I modified your example to show what I mean.

\version "2.16.2" 

  sopV = \relative c'' { c4 c \new Voice = sopL { \voiceOne c2 c } c4 c } 
  altV = \relative c'  { c4 c c c c c c c } 

  \score { 
\new ChoirStaff <<
  \new Staff = upper << 
\new Voice = sop { \voiceOne \sopV } 
\new Voice = alt { \voiceTwo \altV } 
  >> 
  \new Lyrics \with { alignAboveContext = "upper" } \lyricsto sopL { A C
}
  \new Lyrics \lyricsto alt { A B C D E F G H } 
>> 
  }

Thanks, I got it working. I have to rethink the use of capital letters
though since it conflicts with expressions like \clef F.
Also at this point I simply extended my language of choice in
define-note-names.scm, but I suppose I could simply append a new
language-definition to language-pitch-names?!

What exactly do you mean by toplevel? Are these functions defined or applied
differently than regular music functions?

If my message reached you like this then indeed it is.
On my side, via the nabble web interface, it looks fine though.
I'll just post a screenshot and try to make it clearer.

Yes, I noticed and tried (see my second post). Apparently nabble
auto-converted the note 'b' in a chord-construct into a html bold tag.

@Noeck
Thanks for the links. It gave me an idea to experiment with.

Custom note names / octavize pitch

[TaoCG]

Hi all,

I'm looking for a way to octavize a note with the least input possible. I
know there are music functions in the LSR that do this but they aren't very
useful to me because in the music I need this for the octaves usually aren't
successive and it wouldn't really save input if I had to write the function
for single pitches, even if the function name were reduced to a single
letter.
So I was wondering if this maybe could be achieved with custom note names,
maybe a capital letter for an additional octave. After a look at
define-note-names.scm I fear it's not but I thought I ask if a note name
accepts anything else than ly:make-pitch before I try to experiment on my
own.

For illustration I imagine the following snippet (relative)

*4 8 * r  r   |
r8  r   r  r  |

to become this

B4 8 B r  r A |
r8  r A r  r G |

or even better

B4 8 B r q r A |
r8  r A r q r G |

Re: Glissando to a rest

[TaoCG]

This should work. You just have to make sure the space between the two notes
isn't too tight or the glissando won't print. In this case it happens if you
omit the \break.

\relative c''
{
  es4*1/2->\glissando
  \hideNotes
  es,
  \unHideNotes
  r4 r2 | \break
  es1
}

HTH,
Tao

I don't see the ambiguity. The note is tied anyway and not to be articulated
if I were to start playing from that measure. If I want to play the note I
have to look back anyway.

I use reminder accidentals a lot because I believe they greatly improve
sightreadability but as I said earlier I believe a reminder in the discussed
case would be rather disturbing for sightreading, if at all I'd rather
denote the alteration with a small accidental above the notehead but this is
of course personal preference.

Also I don't think this has something to do with classical or non-classical
music or a piece having or not having a key signature.
If I were to write or to play something more "classical" I'd prefer the tied
note without accidental as well.

Regards,
Tao

What makes you think so?
Actually I instinctively thought the opposite.
If I were to see such a note while sightreading I'm almost certain I'd
misinterprete the tie for a slur.
Of course I can only speak for myself here.

I play and typeset a lot of latin american music which has a lot of
syncopation which makes this particlar scene appear quite often.
Maybe I got used to something non-standard but it still seems more logical
to me to omit the tied accidental and treat the measure as if there was no
line break.
That's why I'm curious why Gould states his rule as he does. Is there any
reasoning in his book?

Of course I'm also for flexibility and to have all listed options available
so everyone can choose what s/he prefers.

Regards,
Tao

I must admit I haven't been keeping myself up to date on this topic, maybe
because the last time I was annoyed by this is quite some time ago.
Thanks for the hint, this seems to be the feature I was missing in the past.
I will try it later.

Re: Repeated accidental after tie across line break

[TaoCG]

I wonder... The topics been up a few times already, once by myself years ago
when I just started with LilyPond. I already got used to remove the
accidentals manually, but what I'd really like is an automated way to
suppress them without having to use an override every time, especially since
determining automatic line breaks is also done by lily and the manual
removal can only be done in a secondary editing step.

Re: Hiding one empty staff of three-staff piano score but not two

[TaoCG]

When you override something in the layout-block you do so for every instance
of Staff.
If you want to make only the third staff disappear you have to remove the
override from the layout-block and apply only to that staff like this:

leftTwo = \relative c {
  \override Staff.VerticalAxisGroup #'remove-first = ##t
  s1*8 | %First two lines
  c1 | c | c | c |
}

Re: Aw: Re: Pseudo-handwritten font

[TaoCG]

This is all very interesting, I'd love to have a jazz style font in LilyPond,
though I don't particularly like the Sigler Jazz font. I much prefer their
Swing font.
I was still wondering if there won't be any license issues if the font is
redrawn manually since in the end everyone familiar with the Sigler fonts
will recognize it as such or some might even say: "Hey look, they're using
the same jazz font as Finale/Sibelius."

That to say, one thing I especially liked from the beginning was Lilys
unique font which clearly distinguished it from the commercial counterparts.
Copying a Sigler font will make the output look more similar to Finale or
Sibelius.

One possibility is to use a third voice marked \voiceTwo.

Center barline on first note of measure

[TaoCG]

So, is this possible?
I tried to set the #'first-note property of the BarLine's #'space-alist to 0
but no effect.

What I'm basically trying to achieve is a lot of RhythmicStaff in a
StaffGroup so that the span bars mark the first beat in a measure rather
than separating two measures.
Maybe using bar lines isn't even the right approach but I wouldn't know how
to mimic the span bars.

I was trying to make a tie dashed before and solid after a line break.
I tried \tieHalfDashed but it makes both ties half dashed.

BendAfter maximum length?

[TaoCG]

Is there a property for BendAfter that controls the maximum length?
There is a minimum-length so I was wondering if there's an opposite
equivalent.

Right now the bend is stretched from the notehead until the next rest or
note and if there's a lot of space it seems way overdone.

please help with updating old scheme code

[TaoCG]

So, some years ago I wrote this code for an alternative method of displaying
chord symbols.
It still worked fine in 2.14 but not so in 2.16. I tried running convert-ly
but it didn't change anything.

Details and code can be found in this thread:
http://lilypond.1069038.n5.nabble.com/chord-symbols-as-plain-text-td32481.html

Apparently I have made an update to the code at some point, at least the
file I have been using until recently is somewhat different to the one in
that thread.
So here is the actual version:  chordsymbols.ly
  

I haven't done anything similar in scheme again so I only remember little of
what I did back then.
I'm posting this request for help here in hope that the things to change are
easy to spot for one of you experienced scheme-gurus.

Another thing I noticed is that the function also duplicates textscripts

oct = #(define-music-function (parser location mus) (ly:music?) #{
\makeDuped c c' $mus #})

If I use this in my music I get a warning every time like this:

This seems to be caused by the tuplet. The output looks good though.

Also if you want to mimic the grace notes you might want to use
\graceStyleOn and \graceStyleOff rather than \teeny.
You can find these commands in this thread provided by Thomas Morley:

Ok, don't worry.
I already helped myself by modifying this snippet
http://lsr.dsi.unimi.it/LSR/Item?id=377
since I only needed this for one occasion I tweaked the brackets so to match
the chord.
Thanks for the help.

please help with updating lsr snippet

[TaoCG]

This snippet would be really helpful for me:
http://lsr.dsi.unimi.it/LSR/Item?id=445

But in 2.16.0 it only works on single notes if they are in a chord construct
like 4 or something.
My understanding of scheme is very limited but I thought it might have
something to do with the function checking for equality with 'EventChord so
I tried changing that to 'NoteEvent but it doesn't have the desired effect.

Hmm... did you try what the error message suggests?
In frescobaldi lilypond settings check if the command points correctly to
the windows binary on your machine. If that's not the cause try running
frescobaldi as administrator (Win7 right click -> Run as Administrator).

Collision problem when using \stopStaff and \startStaff

[TaoCG]

I currently have to typeset a lot of this:
skipgliss.png
  

The problem is when I use stop and startStaff to hide the ledgerlines the
dynamics and tupletbracket both move as close to the staff as possible and
collide like you see in the image.

Here is the lily code. When you comment out the stop- and startStaff
commands the bracket and dynamics move to its proper place.

\version "2.16.0"

skipGlissOn =
{
\override NoteColumn #'glissando-skip = ##t
\override NoteHead #'transparent = ##t
\stopStaff
\override Staff.LedgerLineSpanner #'transparent = ##t
\startStaff
}

skipGlissOff =
{
\revert NoteColumn #'glissando-skip
\revert NoteHead #'transparent
\stopStaff
\revert Staff.LedgerLineSpanner #'transparent
\startStaff
}

\relative c'
{
\dynamicUp
\times 8/10 { c32\pp\>\glissando \skipGlissOn c c c b b b b
\skipGlissOff b\! r }
}

double dashed barline

[TaoCG]

I found two different approaches to print double dashed bar lines here:
http://lilypond.1069038.n5.nabble.com/Fine-with-dashed-double-barline-occurring-in-middle-of-bar-td17372.html

But I need the barline to span a piano and choir staff which neither method
currently supports.
Anyone has an alternative approach or could help implement it into one of
the existing ones?

I got rid of the additional barnumber by setting the stencil to ##f just
before the \bar command.
Still if someone knows of an automatic way that would be great.

Ah sorry, it didn't occur to me that this might not be standard behaviour (I
suppose because of the parentheses, they make it look intentional).
I made a short snippet. Apparently the additional bar number is a result of
both of the overrides, comment out either and it will disappear. In my score
I use bar numbers every 5 measures.

\version "2.16.0"

{
  \override Score.BarNumber #'break-visibility = #end-of-line-invisible
  \set Score.barNumberVisibility = #(every-nth-bar-number-visible 1)
  r2 \bar "dashed" r
}

unwanted barnumber

[TaoCG]

When I typeset a dashed barline in the middle of a bar lilypond prints an
additional Barnumber in parentheses above it. Is there a way to avoid this?

Dynamic collisions

[TaoCG]

I'm getting a lot of colliding dynamics like in the attached pdf. 
sf_03_m14.pdf
  
If I try to isolate that specific measure the dynamics don't collide:

\version "2.16.0"

\score
{
  <<
\new PianoStaff
<<
  \new Staff \relative c'''
  {
\override Score.Hairpin #'circled-tip = ##t
\override Score.Hairpin #'minimum-length = #10
r4 \times 2/3 { r8 d4~\< } \times 2/3 { d8\\> r4\! } r4
  }
  \new Staff \relative c'
  {
\clef F
<<
  { r16 d4..~^\< d\p\> r16\! } \\
  { r2 \times 2/3 { r4 c8~\< } \times 2/3 { c\f\> r4\! } }
>>
  }
>>
  >>
}

Does anyone have an idea what might be causing this and how to resolve it?

Thank you, that looks very good.
The parentheses collide with glissando lines. Would it be possible to
resolve that collision automatically?

special accidentals

[TaoCG]

Hello,

I currently have to copy parts from a modern opera and sometime it has these
accidentals.
My guess is that these are just a different way to type quarter tones but
I'm not sure since I haven't seen them before. Anyone know if this is true
because then I'd just replace them with the standard lily accidentals for
quarter tones.

I need to typeset a glissando from e-flat to e and I'd like it to look as if
it'd go upward, right now the line is straight and not actually visible
because it collides with the staff line.
I suppose the property to edit is normalized-endpoints but changing it

Thanks, I tried that but I still get around 20 or so negative skips with
only the first measure.

As much as I'd like to get this to work I believe I'd be best off reytyping
this manually because I don't have much time to finish this and it seems
it'd require some time to get into the materia first.

Anyway, I'd have to ask for permission first before I could send you the
file but let me know if you're interested to see it.

When I'm done with this I'll experiment more with musicxml to be prepared
for future projects. This is my first big copying job and I haven't foreseen
the possible usefulness of this tool.

Thanks for the help and input so far.

Unfortunately no. It's a very complex piece which I got in Sibelius format
which I exported then to musicxml hoping I'd be able to convert it to
lilypond. Actually I have no idea how musicxml works.
It has no pickup measure but definitely multiple voices.

You think if it's too complex musicxml2ly can't handle it?
Maybe I'll just have to copy it by hand.

Modern Flags with 2.16.0

[TaoCG]

Dear List,

I'm currently trying to migrate from 2.14 to 2.16 and can't find how to
create modern flags.
I read that flags are now internally separated from stems but the style
property of a flag doesn't seem to support modern-straight as it used to in
2.14.

Am I looking at the wrong place or is this feature lost?

Thanks for the help and expect more questions in the future since it appears
there are some fundamental changes in the versions.

Regards,
Tao

Issue with pango font tree and global staff size

[TaoCG]

Dear list,

I am having a problem with using a custom pango font tree and
set-global-staff-size at the same time.
If I set the staff size before the \paper block only the staff lines change,
the feta glyphs and text don't.
But if I set the staff-size after the \paper block it resets the pango font
tree to the default lily fonts.

I made two snippets for demonstration. Both tested with 2.14.2 and 2.15.39
with the same results.


%
% 1.ly
%

music = { a4^"Markup" b c' d' }

\paper
{
#(define fonts
(make-pango-font-tree
"Linux Libertine"
"Linux Biolinum"
"Courier New"
(/ 20 20)))
}

#(set-global-staff-size 15)

\score
{
<< \new Staff \music >>
\layout { }
}


%
% 2.ly
%

#(set-global-staff-size 15)

music = { a4^"Markup" b c' d' }

\paper
{
#(define fonts
(make-pango-font-tree
"Linux Libertine"
"Linux Biolinum"
"Courier New"
(/ 20 20)))
}

\score
{

\layout { }

Thanks, this works great.
I just had to modify it a little so I could control the duration with a
variable:

#(define duration 1)

#(define (len d) (ly:export (ly:make-duration d 0)))

{
r#(len duration)
#(set! duration 2)
r#(len duration)
}

Thanks. It's a start.
I was wondering now how would you determine the time signature if it wasn't
for a music function, e.g. is it possible to store the value in another
variable?
Also, is there some info about the Timing context because I couldn't find it
in the Internals.

How to override VoltaBracket once?

[TaoCG]

Hi,

what I am basically trying to do is to override a property of VoltaBracket
once but I can't figure out where to place the command in the code. When I
remove \once it works fine. I know I can just revert the property but I am
still curious why it won't work.

Actually I have a coda sign in the alternative-part and I set its
outside-staff-priority to 0 to have it below the volta bracket but now the
volta bracket seems to be to far away.
The following snippet produces what I want but if I try to override with
\once nothing happens.

\version "2.13.52"


music =
{
\repeat unfold 6 { c'1 }
}

frame =
{
\override Score.VoltaBracket #'extra-offset = #'(0 . -1.5)  
\repeat volta 2
{   
s1*2
}
\alternative
{
{ s1*2 }
{
s1
\once \override Score.RehearsalMark 
#'outside-staff-priority = #0
\mark \markup \musicglyph #"scripts.coda"
s1
}
}
\bar "||"
}

\score
{
<<
\new Staff = "s" \new Voice = "v" << \frame \music >>
>>
}

Thanks. It seems the solution on the page you posted in issue 1486 does the

I still don't see why 1486 is fixed though. The problem is still there and I
don't think I have seen a potential workaround in the docs, just a note in
CHANGES that only said  lyrics above a staff have to set #'staff-affinity =
#DOWN or use alignAboveContext but that really isn't a change.

Strange behaviour of Lyrics above Staff

[TaoCG]

Hi,

I am having weird results with Lyrics above the Staff.
I tried to reduce the problem to a small snippet.

What I notice is that the distance to the staff is very large except on the
first system on a page.
Also the distance raises if you put a rehearsal mark at the beginning of a
system although they don't collide.

I tried moving the lyrics closer to the staff by overriding the
#'outside-staff-padding property of LyricText but with no effect at all.

Here comes the snippet. If you remove the rehearsal mark you'll see that the
lyrics will move much closer to the staff than on the following systems.

\version "2.13.52"

outer = 40
inner = 8

\header
{
title = "Test"
}

music =
{
\mark \default
\repeat unfold \outer { \repeat unfold \inner { c'8 } \break }
}

text = \lyricmode
{
\repeat unfold \outer { \repeat unfold \inner { foo } }
}

\score
{
<<
\new Staff = "s" \new Voice = "v" \music
\new Lyrics \with { alignAboveContext = "s" }
{
\set associatedVoice = "v" { \text }
}
>>
}

Well, I am no expert in MIDI, so anyone correct me if I am wrong, but to my
knowledge lilypond doesn't contain any soundfont at all. The MIDI-files
generated by Lilypond are just played via the GM-Standard Soundfont that
comes with your operating system.

I suggest you to take a look at the file drumpitch-init.ly in
usr\share\lilypond\current\ly of your Lilypond directory and analyze it
until you understand what it does. Part of it is described here:
http://lilypond.org/doc/v2.12/Documentation/user/lilypond/Common-notation-for-percussion#Custom-percussion-staves

I don't work with MIDI output but I believe if you make your custom
drum-pitch tables you can alter the midi-drumpitch table accordingly, you'll
just have to know which MIDI-representation each sound of your soundfont has
and later make sure that your MIDI-file is played back using your djembé
soundfont.

I hope this was of some help.

Regards,
Tao

Maybe you should install the latest development release.
I think some subproperties of the VerticalAxisGroup properties have been
renamed (and rewritten?).
At least I remember that I had to replace #'space with #'basic-distance when
I installed 2.13.51 so the properties you are trying to override probably
aren't specified yet in 2.13.4

Tao

Well in my case the new bar is different to bar X in the vocal and horn
parts but is not in the rhythm section, you see?
To be precise, the harmonic structure of the song is AABAAB but the melodic
part is ABCDBC and to fit the music for the rhythm section on less pages I
am going to put it like this:
§ |: A :| B  dal segno(I hope this is clear)


So the repeated A part would be the B part for vocals and horns and in
rehearsals I prefer to work with bar numbers instead of rehearsal marks
that's why I wanted to have two at the same time.

Tao

Wow, thanks for your efforts.
I don't really understand this issue though.

Well, actually I have a global frame with rehearsal marks etc., which I
wanted to use for all parts but I guess I'll just have to make an
alternative one for the rhythm section in this case.

Thanks for your help.
Unfortunately this seems to neutralize all \break commands.
I tried to reproduce this in a small snippet:

\version "2.13.51"

{
c'1
\break
\set Score.skipTypesetting = ##t
s1
\set Score.skipTypesetting = ##f
\break
c'1
}

Actually I have:

\context {
   \Staff \RemoveEmptyStaves
}

Does this make any difference?

I tried changing it to your example but the result seems to be the same.
Again I tried to remove the rehearsal mark to see if it is keeping the staff
alive but apparently it's not and then only the bar number is seen taking up
vertical space for a whole staff.

I forgot to mention that I use the development version, maybe this is a bug?

Tao
